But, when active, these guys are social, climb trees, swim, and blend in with their surroundings. This species' primary diet is fish and invertebrates, however it will feed opportunistically on larger prey. Along the way the following tributaries drain into the Potomac: Antietam Creek, Shenandoah River, Catoctin Creek, Catoctin Creek, Tuscarora Creek, Monocacy River, Little Monocacy River, Broad Run, Goose Creek, Broad Run, Horsepen Branch, Little Seneca Creek, Tenmile Creek, Great Seneca Creek, Old Sugarland Run, Muddy Branch, Nichols Run, Watts Branch, Limekiln Branch, Carroll Branch, Pond Run, Clarks Branch, Mine Run Branch, Difficult Run, Bullneck Run, Rock Run, Scott Run, Dead Run, Turkey Run, Cabin John Creek, Minnehaha Branch, and Little Falls Branch. In 2005 two federal agencies, the US Geological Survey and the Fish and Wildlife Service, began to identify fish in the Potomac and tributaries that exhibited "intersex" characteristics, as a result of endocrine disruption caused by some form of pollution. The source of the North Branch Potomac River is at the Fairfax Stone located at the junction of Grant, Tucker and Preston counties in West Virginia. Smallmouth bass are ferocious hunters and will eat crayfish, insects, and other fishes. The Potomac River then flows past Maryland farmland before dropping 77 feet within one mile at the boulders of the Great Falls. Watermen catch two 8-footers on same day", "THE POTOMAC RIVER AMERICAN SHAD RESTORATION PROJECT", "Sources of Northern Virginia Drinking Water", Multiple Paleozoic Metamorphic Histories, Fabrics, and Faulting in the Westminster and Potomac Terranes, Central Appalachian Piedmont, Northern Virginia and Southern Maryland, Interstate Commission on the Potomac River Basin (ICPRB), Trout and Smallmouth Fishing on the North Branch of the Potomac, Wade and Shoreline Fishing the Potomac River for Smallmouth Bass, https://en.wikipedia.org/w/index.php?title=Potomac_River&oldid=1124649201, ------------------------------------------------------------------, Limit of navigation; Eastern boundary of the. First, it flows northeast by the communities of Bloomington, Luke, and Westernport in Maryland and then on by Keyser, West Virginia to Cumberland, Maryland. If you pry the leech off by scraping your nail between your skin and its mouth, its more likely to come away clean, whereas if you shock the leech by salting it or spraying DEET on it, the leech may vomit its stomach contents back into the wound. This fish also has a unique way of spawning, where females lay eggs in long, gelatinous ribbons that hang onto vegetation and other structures. Bull sharks are unique in that, though they live mostly in saltwater, they can tolerate freshwater. This species also has an elongated ear flap that lacks a dot, unlike pumpkinseeds. This species has a disc-shaped body that is speckled with olive green, blue, orange, and yellow, and they have orange and blue waves running across their faces. The Potomac River runs 405 miles (652km) from Fairfax Stone Historical Monument State Park in West Virginia on the Allegheny Plateau to Point Lookout, Maryland, and drains 14,679 square miles (38,020km2). The source of the North Branch is at the Fairfax Stone located at the junction of Grant, Tucker, and Preston counties in West Virginia. Although Church Pond looked like ideal leech habitat, neither Hoefler who was testing for mercury, having gotten a grant to collect samples in Adirondack waters nor this reporter felt like offering the leeches a toe. Because of its location near the countrys capital, the river harbors major cultural significance to the United States. [13] In 1608, Captain John Smith explored the river now known as the Potomac and made drawings of his observations which were later compiled into a map and published in London in 1612. Along the way the following tributaries drain into the Potomac: Pimmit Run, Gulf Branch, Donaldson Run, Windy Run, Spout Run, Maddox Branch, Foundry Branch, Rock Creek, Rocky Run, Tiber Creek, Roaches Run, Washington Channel, Anacostia River, Four Mile Run, Oxon Creek, Hunting Creek, Broad Creek, Henson Creek, Swan Creek, Piscataway Creek, Little Hunting Creek, Dogue Creek, Accotink Creek, Pohick Creek, Pomonkey Creek, Occoquan River, Neabsco Creek, Powell's Creek, Mattawoman Creek, Chicamuxen Creek, Quantico Creek, Little Creek, Chopawamsic Creek, Tank Creek, Aquia Creek, Potomac Creek, Nanjemoy Creek, Chotank Creek, Port Tobacco River, Popes Creek, Gambo Creek, Clifton Creek, Piccowaxen Creek, Upper Machodoc Creek, Wicomico River, Cobb Island, Monroe Creek, Mattox Creek, Popes Creek, Breton Bay, Leonardtown, St. Marys River, Yeocomico River, Coan River, and Hull Creek. Just last year, a fisherman caught a 310-pound, 8.6 foot long bull in the river. According to Dr Janet Mann of Georgetown University's Potomac-Chesapeake Dolphin Project, more than 500 individual members of the species have been identified in the Potomac during this period. Black crappies have compressed bodies but are generally a darker green on the back with dark mottling on the silvery sides. So lets all thank the bull shark for keeping our waters biodiverse, wildlife diseases under control, and regulating our ecosystem! These fish are very aggressive and will outcompete native fish species for food such as crayfish, fish eggs, insects, and smaller fishes. U.S. Early European colonists who settled along the Potomac found a diversity of large and small mammals living in the dense forests nearby. Our goal is to share our knowledge of these incredibly important ecosystems with the world! The 1859 siege of Harper's Ferry at the river's confluence with the Shenandoah was a precursor to numerous epic battles of the American Civil War in and around the Potomac and its tributaries, such as the 1861 Battle of Ball's Bluff and the 1862 Battle of Shepherdstown. The similar pore pattern, however, led Phillips and the other scientists to name the new species Macrobdella mimicus, after the Greek word for imitator or actor.. The stream gradient of the entire river is 0.14%, a drop of 930 m over 652km. It runs 380 miles beginning in the Allegheny Mountains and emptying in the Chesapeake Bay at Havre de Grace, Maryland. [14], The similarity of the name to the Ancient Greek word for river, potamos, has been noted for more than two centuries but it appears to be due to chance.[16][17][18]. Like all catfish, the channel catfish does not have scales and has barbels on the upper and lower jaw; however, the channel catfish can be distinguished by its deeply forked tail, silvery body, and overbite. Weekly readings will reveal water quality and bacteria levels", "Need a bigger boat: 35-pound bass caught on the Potomac River", "Historic Crests for Potomac near Washington, DC (Little Falls)", "World War II-Era Flood Was the Worst in D.C.'s History", "Sharks! At Forks of Waters, the South Branch joins with Strait Creek and flows north across the Virginia/West Virginia border into Pendleton County. 2023 Smithsonian Magazine The Potomac runs through the Great Falls and then funnels downstream through the narrow Mather Gorge. Privacy Statement Not all of them have been catalogued, but as far as we know, Macrobdella decora is the only hematophagic, or blood-sucking, freshwater leech found in the Adirondacks. Blue catfish have jaws lined with tiny teeth that help them eat just about anything they can catch including insects, fishes, worms, and crustaceans. A comprehensive metro . C&O Feeder Dam No. Among the denizens of the Potomac's banks, beavers and otters met a similar fate, while small populations of American mink and American martens survived into the 20th century in some secluded areas. Lila Thulin is the former associate web editor, special projects, for Smithsonian magazine and covers a range of subjects from women's history to medicine. They also have excellent vision both during the day and at night. Steve Kulina, head lifeguard at Lake Colby Beach, said they havent seen any there. The South Branch Potomac River lies completely within the state of West Virginia except for its headwaters, which lie in Virginia. Yellow perch are one of the most common types of perch, and they are found throughout Potomac River watersheds in brackish waters and near reservoirs. Captain John Smith Chesapeake National Historic Trail, Chesapeake Bay , Potomac Heritage National Scenic Trail, Star-Spangled Banner National Historic Trail, Download the official NPS app before your next visit. 7 and Guard Lock No. On hot summer days leeches are most active.In winter they burrow in mud just below the frost line. . Except for a small portion of its headwaters in West Virginia, the North Branch Potomac River is considered part of Maryland to the low-water mark on the opposite bank. Whats scarier is that the Indiana bat has been endangered since 1967. The source of the South Branch is located near Hightown in northern Highland County, Virginia. For one thing, leeches are a favorite food of bass and loons, so while they continue to grow while they live, they dont often live long enough to become very big. For instance, this species can make very quick stops by spreading out their pectoral fins. As it flows from its headwaters down to the Chesapeake Bay, the Potomac traverses five geological provinces: the Appalachian Plateau, the Ridge and Valley, the Blue Ridge, the Piedmont Plateau, and the Atlantic coastal plain. However, Jennifer Burgess, owner of the Packbasket Diner in Gabriels, said one of her friends camped there for a week, with her kids, and they were in the water all the time. These fish get their name from the bluish hue surrounding the gill covers. Menu. Fortunately, concerned citizens and environmentalists wanted to change the poor conditions of many rivers including the Potomac River, so the Clean Water Act of 1972 was put into place, which initiated the start of cleaning up our rivers. Thank goodness copperheads have begun hibernation! Unlike their (mostly) terrestrial cousins, the earthworms, leeches are flattened in cross section; like earthworms, their bodies are soft but very muscular. Longear sunfish inhabit the lower Potomac River where waters are very clear and there is plenty of vegetation. Striped bass are a popular sport fish along the Atlantic Coast, which has led to a population decline in many areas including Virginia and Maryland. It has somewhat fearsome features, sharp teeth and a pointy tip at the end of its tail. Those that are parasitic latch onto a variety of vertebrates: amphibians, reptiles [turtles], birds and mammals.. Into Grant, the South Branch follows the western side of Cave Mountain through the 20-mile (32km) long Smoke Hole Canyon, until its confluence with the North Fork at Cabins, where it flows east to Petersburg. Males look slightly different than females during breeding season because males will develop a dark throat. This species is known for its golden yellow to greenish body covered in 6 8 dark vertical bars. As with any organism, they have a story to tell and usually a very interesting story., Rumors of leeches in Jones Pond could not be confirmed by the Enterprise. The last time a new leech species was described in North America was 1975. Head life guard Steve Kulina said the wave action and sandy bottom at Lake Colby help keep the beach leech-free. Fayton notes there are two reasons for this: one is the leeches usually perish after their breeding season and the other is that they're an estuarine species that will ultimately die in. Striped bass have bodies that are laterally compressed with green or blue backs and silver iridescent sides. (Enterprise photo Glynis Hart), Milewski pointed out that not all leeches are parasitic bloodsuckers. ). Cookie Policy Just last year, a fisherman caught a 310-pound, 8.6 foot long bull in the river. His recipe is printed here with permission. A future question for researchers will be to further document the range of M. mimicus to better understand what geographic factors might have led to the divergence of the species from the other members of the Macrobdella genus. These fish have streamlined bodies with greenish-blue backs, silvery sides, and a white belly. Striped bass are the state fish of Maryland, and they can be found mainly near the mouth of the Potomac River in waters that are cool, clear, and deep. At least anecdotally [according to Charlie Wilson, see below], there are leeches in Jones Pond. At Moorefield, the South Branch is joined by the South Fork South Branch Potomac River and runs north to Old Fields where it is fed by Anderson Run and Stony Run. This species has a wider body compared to other sunfish, and these bodies are blue-green in color with black dots and white bellies. Are there sharks in the Potomac river? [49], Since 2015, perhaps as a result of warmer temperatures, rising water levels in the Chesapeake Bay and improving water quality in the Potomac, unprecedented numbers of Atlantic bottle-nosed dolphins have been observed in the river. "Potomac" is a European spelling of Patawomeck, the Algonquian name of a Native American village on its southern bank. Bluegills average around 7.5 inches in length, and weigh around half a pound as adults. The Potomac River (/ptomk/ (listen)) drains the Mid-Atlantic United States, flowing from the Potomac Highlands into Chesapeake Bay. | This deep section is in the Potomac River's tidal portion, just below Washington, D.C. They showed that for some leech specimens, the genetic fingerprints differed by as much as six and eleven percent from the others. When leeches bite, they inject an anticoagulant called hirudin. Flowing north of Romney, the river still follows the eastern side of Mill Creek Mountain until it creates a horseshoe bend at Wappocomo's Hanging Rocks around the George W. Washington plantation, Ridgedale. A Guide to the Snakes of Virginia (Virginia Department of Game and Inland Fisheries, Wildlife Diversity Division, Special Publication No. This detail from that map shows his rendition of the river that the local tribes had told him was called the "Patawomeck". In the Potomac River, the largest white catfish caught on record was 23 inches long and weighed 8.27 pounds. TRICK: Walking through the woods on a summer day requires extra focus to make sure you do not accidentally crush a Death Adder underfoot. Bull sharks are unique in that, though they live mostly in saltwater, they can tolerate freshwater. [44][45] Many types of sunfish are also present in the Potomac and its headwaters. [2] The highest average daily flow ever recorded on the Potomac at Little Falls, Maryland (near Washington, D.C.), was in March 1936 when it reached 426,000 cubic feet (12,100m3)/s. Even if you dont see them, theyre probably there. Largemouth bass get their name from their mouth, which extends past the eye, unlike smallmouths. Once the Potomac drops from the Piedmont to the Coastal Plain at the Atlantic Seaboard fall line at Little Falls, tides further influence the river as it passes through Washington, D.C. and beyond. Being situated in an area rich in American history and American heritage has led to the Potomac being nicknamed "the Nation's River". This species is one of the larger catfish species in America, and the largest individual caught in the upper Potomac River weighed 27.92 pounds! The first steam ferry across the Potomac was named The Washington. In the summer of 2015, when Smithsonian research zoologist Anna Phillips and other scientists were standing in slow-moving swamp water, letting leeches latch onto their bare legs or gathering them up in nets from muddy pond bottoms, they didnt realize that some of the bloodsuckers theyd collected belonged to an entirely new species. It ran from Georgetown to Thorny Point at the mouth of Aquia Creek, with daily stops at Alexandria. Even better, since the only treats theyre interested in are insects, we can thank these critters for helping to keep the mosquito population under control. .mw-parser-output .RMbox{box-shadow:0 2px 2px 0 rgba(0,0,0,.14),0 1px 5px 0 rgba(0,0,0,.12),0 3px 1px -2px rgba(0,0,0,.2)}.mw-parser-output .RMinline{float:none;width:100%;margin:0;border:none}.mw-parser-output table.routemap{padding:0;border:0;border-collapse:collapse;background:transparent;white-space:nowrap;line-height:1.2;margin:auto}.mw-parser-output table.routemap .RMcollapse{margin:0;border-collapse:collapse;vertical-align:middle}.mw-parser-output table.routemap .RMreplace{margin:0;border-collapse:collapse;vertical-align:middle;position:absolute;bottom:0}.mw-parser-output table.routemap .RMsi{display:inline;font-size:90%}.mw-parser-output table.routemap .RMl1{padding:0 3px;text-align:left}.mw-parser-output table.routemap .RMr1{padding:0 3px;text-align:right}.mw-parser-output table.routemap .RMl{text-align:right}.mw-parser-output table.routemap .RMr{text-align:left}.mw-parser-output table.routemap .RMl4{padding:0 3px 0 0;text-align:left}.mw-parser-output table.routemap .RMr4{padding:0 0 0 3px;text-align:right}.mw-parser-output table.routemap>tbody>tr{line-height:1}.mw-parser-output table.routemap>tbody>tr>td,.mw-parser-output table.RMcollapse>tbody>tr>td,.mw-parser-output table.RMreplace>tbody>tr>td{padding:0;width:auto;vertical-align:middle;text-align:center}.mw-parser-output .RMir>div{display:inline-block;vertical-align:middle;padding:0;height:20px;min-height:20px}.mw-parser-output .RMir img{height:initial!important;max-width:initial!important}.mw-parser-output .RMir .RMov{position:relative}.mw-parser-output .RMir .RMov .RMic,.mw-parser-output .RMir .RMov .RMtx{position:absolute;left:0;top:0;padding:0}.mw-parser-output .RMir .RMtx{line-height:20px;height:20px;min-height:20px;vertical-align:middle;text-align:center}.mw-parser-output .RMir .RMsp{height:20px;min-height:20px}.mw-parser-output .RMir .RMtx>abbr,.mw-parser-output .RMir .RMtx>div{line-height:.975;display:inline-block;vertical-align:middle}.mw-parser-output .RMir .RMts{font-size:90%;transform:scaleX(.89)}.mw-parser-output .RMir .RMf_{height:5px;min-height:5px;width:20px;min-width:20px}.mw-parser-output .RMir .RMfm{height:100%;min-height:100%;width:4px;min-width:4px;margin:0 auto}.mw-parser-output .RMir .RMo{width:2.5px;min-width:2.5px}.mw-parser-output .RMir .RMc{width:5px;min-width:5px}.mw-parser-output .RMir .RMoc{width:7.5px;min-width:7.5px}.mw-parser-output .RMir .RMd{width:10px;min-width:10px}.mw-parser-output .RMir .RMod{width:12.5px;min-width:12.5px}.mw-parser-output .RMir .RMcd{width:15px;min-width:15px}.mw-parser-output .RMir .RMocd{width:17.5px;min-width:17.5px}.mw-parser-output .RMir .RM_{width:20px;min-width:20px}.mw-parser-output .RMir .RM_o{width:22.5px;min-width:22.5px}.mw-parser-output .RMir .RM_c{width:25px;min-width:25px}.mw-parser-output .RMir .RM_oc{width:27.5px;min-width:27.5px}.mw-parser-output .RMir .RM_d{width:30px;min-width:30px}.mw-parser-output .RMir .RM_od{width:32.5px;min-width:32.5px}.mw-parser-output .RMir .RM_cd{width:35px;min-width:35px}.mw-parser-output .RMir .RM_ocd{width:37.5px;min-width:37.5px}.mw-parser-output .RMir .RMb{width:40px;min-width:40px}.mw-parser-output .RMir .RMcb{width:45px;min-width:45px}.mw-parser-output .RMir .RMdb{width:50px;min-width:50px}.mw-parser-output .RMir .RMcdb{width:55px;min-width:55px}.mw-parser-output .RMir .RM_b{width:60px;min-width:60px}.mw-parser-output .RMir .RM_cb{width:65px;min-width:65px}.mw-parser-output .RMir .RM_db{width:70px;min-width:70px}.mw-parser-output .RMir .RM_cdb{width:75px;min-width:75px}.mw-parser-output .RMir .RMs{width:80px;min-width:80px}.mw-parser-output .RMir .RMds{width:90px;min-width:90px}.mw-parser-output .RMir .RM_s{width:100px;min-width:100px}.mw-parser-output .RMir .RM_ds{width:110px;min-width:110px}.mw-parser-output .RMir .RMbs{width:120px;min-width:120px}.mw-parser-output .RMir .RMdbs{width:130px;min-width:130px}.mw-parser-output .RMir .RM_bs{width:140px;min-width:140px}.mw-parser-output .RMir .RM_dbs{width:150px;min-width:150px}.mw-parser-output .RMir .RMw{width:160px;min-width:160px}.mw-parser-output .RMir .RM_w{width:180px;min-width:180px}.mw-parser-output .RMir .RMbw{width:200px;min-width:200px}.mw-parser-output .RMir .RM_bw{width:220px;min-width:220px}.mw-parser-output .RMir .RMsw{width:240px;min-width:240px}.mw-parser-output .RMir .RM_sw{width:260px;min-width:260px}.mw-parser-output .RMir .RMbsw{width:280px;min-width:280px}.mw-parser-output .RMir .RM_bsw{width:300px;min-width:300px}. There are reported leech infestations in various human body sites such as the nose, pharynx, larynx, esophagus, rectum and bladder (2). Macrobdella decora resembles an earthworm, in that it has two mouths, one at each end. Controls on phosphorus, one of the principal contributors to eutrophication, were implemented in the 1980s, through sewage plant upgrades and restrictions on phosphorus in detergents. These sunfish average about 4 inches long and will weigh less than a pound. The spelling of the name has taken many forms over the years from "Patawomeck" (as on Captain John Smith's map) to "Patomake", "Patowmack", and numerous other variations in the 18th century and now "Potomac". As an Amazon Associate we earn from qualifying purchases. After two additional horseshoe bends (meanders), the South Branch flows under the old Baltimore and Ohio Railroad mainline between Green Spring and South Branch Depot, and joins the North Branch to form the Potomac. . Be aware that even small changes in water levels can dramatically increase the difficulty of the . Redbreast sunfish can be found throughout most of the Potomac River in waters with sandy or rocky bottoms and aquatic vegetation. Bait the trap with 1/4 cup of raw meat, submerge it in your pond, and weigh it down with a rock to keep it in place and discourage snapping turtles. And even though the gross-out factor is high, leeches dont pose much danger. From 1957 to 1996, the Maryland Department of the Environment (MDE) routinely issued permits applied for by Virginia entities concerning the use of the Potomac. Currently, white perch populations are doing extremely well in the Potomac River with abundance exceeding the historic mean. Privacy Policy | Cookie Policy | Contact | About, List of Common Potomac River Fish Species [Updated], Potomac River Pollution & Conservation Efforts, List of Fish Species in the Potomac River, 7) Black crappie (Pomoxis nigromaculatus), 10) Channel catfish (Ictalurus punctatus), 13) Largemouth bass (Micropterus salmoides), 14) Smallmouth bass (Micropterus dolomieu), 9 Best Plants That Repel Slugs 2023 [Plants Slugs Hate], List of Prehistoric Fish Still Alive Today [Updated], List of Fish Species in Lake Mohave 2023 [Updated], List of North American Chub Species 2023 [ID + Pictures], List of Turtle Species in Virginia 2023 (ID + Pics), 10 Best Ferns for Hanging Baskets 2023 [Updated], List of Turtle Species in Utah 2023 (ID + Pics). Yes, thats terrifying. However, a young man fishing from his kayak and who, incidentally, caught six pike said hed used them to catch fish. The river provides a critical link to the Bay; before roads crisscrossed the landscape, the Potomac transported trade goods and . The river then travels on a northeastern course along the western side of Jack Mountain (4,045ft), followed by Sandy Ridge (2,297ft) along U.S. Route 220. Because this family of medicinal leeches has been thoroughly studied, finding a new Macrobdella species is exciting, says Michael Tessler, a comparative biologist who works with leeches at the American Museum of Natural History, in an email. Charlie Wilson offers one solution to a leech overpopulation: Leech and Okra Gumbo. [32], By the end of the 20th century, notable success had been achieved, as massive algal blooms vanished and recreational fishing and boating rebounded. Reduce heat and mount the sauce with 1/2 stick butter. Like worms, leeches are hermaphroditic (also called monoecious )they have both male and female sexual organs. Washington, D.C. began using the Potomac as its principal source of drinking water with the opening of the Washington Aqueduct in 1864, using a water intake constructed at Great Falls. Dozens of small, vibrant rivers and streams flow through forests, farms, towns, and rural communities, coming together to form the Potomac. Advertising Notice These fish have yellow or green eyes and orange-red tinted fins. Leeches are a fairly common resident of the Mountain Lake pond. Maryland claimed Virginia lost its riparian rights by acquiescing to MDE's permit process for 63 years (MDE began its permit process in 1933). At McNeill, the South Branch flows into the Trough where it is bound to its west by Mill Creek Mountain (2,119ft) and to its east by Sawmill Ridge (1,644ft). The river splits and forms a series of large islands while it heads northeast to Moorefield. Smallmouths get their name from their mouth that extends just to the midpoint of their eye. The Potomac Rivers ecologically rich habitat is home to over a thousand species of animals, and some of the coolest ones around are also the creepiest. [33] Enactment of the 1972 Clean Water Act led to construction or expansion of additional sewage treatment plants in the Potomac watershed. Maryland, West Virginia, Pennsylvania, Virginia, and the District of Columbia agreed to establish the Interstate Commission on the Potomac River Basin. What do we know about baby dolphins living in the Potomac River? The Upper Potomac River Commission treatment plant in Westernport, MD, begins operation; it is designed to clean up pollution in the North Branch Potomac. This species is generally nocturnal, so they will hunt during the night for small fishes, crustaceans, and insects. When detailed studies were issued by the Corps in the 1950s, they met sustained opposition, led by U.S. Supreme Court Justice William O. Douglas, resulting in the plans' abandonment. Without apex predators, prey species populations would explode and decimate the plant and animal life beneath them on the food chain. They are attracted to water disturbance around docks and swimming areas. This species is generally piscivorous and will hunt for other fishes at night. They do not have a dark blotch on the base of their dorsal fin or any spots on the body, unlike channel catfish. These fish grow to be about 5 - 8 inches long and weigh around 8 - 12 ounces. While browsing images on Flickr, Phillips noticed a photograph of leeches on the leg of a man in South Carolina, a location she wouldnt expect to see M. decora. M. decora had four accessory pores grouped in two rows of two, just like the outlier group, but the new species had a set of pores located several millimeters farther back on their body. You dont have to go very far to find something new, she says. All of Washington, D.C., the nation's capital city, also lies within the watershed. As their name suggests, bull sharks are big and quite aggressive. The river not only divided the Union from the Confederacy, but also gave name to the Union's largest army, the Army of the Potomac. . Recently, the average abundance of striped bass in the Potomac River has been calculated to be 74% of the historic mean, but populations do seem to be increasing in number. Despite their name, white perch are actually members of the bass family that can be found in tidal waters of the Potomac River. She gathered leeches in the state, found more of the new species, and then turned to collections belonging to museums and the federal government in North Carolina, Virginia and the District of Columbia, including the Smithsonians invertebrate zoology collection, which includes 5,310 lots of leech specimens. These fish are an olive-green color with vertical bands on the side of the body, and these bands tend to fade with age. Scientists know that a genetic difference of more than two percent in a telltale part of the genome typically indicates the two creatures may be distinct species. They also have darker vertical bands across their bodies and a dark spot on their dorsal fin. Known as the Nations River, the Potomac River is the fourth largest river on the East Coast of the United States, which spans about 405 miles long. There are leeches in the TN river system.. see one every once in a while. They attach to their hosts and remain there (5). On December 9, 2003, the Court agreed in a 72 decision. Spread the word about their conservation and soon this 170-million year old species may be back in our hometown river! TRICK: There are not too many creatures that can say they outlived the DINOSAURS, but sturgeons are one of them. (While leeches are hermaphrodites, they mate with other leeches, and accessory pores secrete mucus that allows the mating leeches to stick together.) Bull sharks are unique in that, though they live mostly in saltwater, they can tolerate freshwater. That evidence, says Phillips, stood out like a (blood-)red flag. [42][43], A variety of fish inhabit the Potomac, including bass, muskellunge, pike, walleye. There is still some walleye to be caught over the Michigan and Ohio dumping grounds. Many are predators that feed on other invertebrates. Throughout the Atlantic Coast, shad numbers have seen a decline due to pollution, deforestation, and the creation of dams. TRICK: Great. To make a leech trap, take a coffee can with a plastic lid and poke it full of holes. These fish have dark vertical bands along the sides of their bodies, and their gill covers have spines. One of the significant pollution control projects at the time was the expansion of the Blue Plains Advanced Wastewater Treatment Plant, which serves Washington and several surrounding communities. ", Lang, Marissa J. Smithsonian researcher describes a previously unknown species of olive-green bloodsucker that has three jaws with up to 59 teeth, Former Associate Editor, Special Projects. The Corps built a supplementary water intake for the Washington Aqueduct at Little Falls in 1959. At Cumberland, the river turns southeast. These birds did it first, A Day in the Life: Avery Siler, our Director of Land Conservation, Ring in the new year with these 5 resolutions to help protect the Potomac River. Return the leeches to the pot, add 1 cup chicken stock, 1/2 cup dry sherry, deglaze the pan, and reduce liquid by half. TRICK: Yes, their are sharks in the Potomac River! Return the leeches to the pot, add 1 cup chicken stock, 1/2 cup dry sherry, deglaze the pan, and reduce liquid by half. All leeches' bodies are composed of 34 segments. [25] Several other dams were proposed for the Potomac and its tributaries. As their name suggests, bull sharks are big and quite aggressive. That means that they can accurately strike a prey animal just by sensing its body heat. General Robert E. Lee crossed the river, thereby invading the North and threatening Washington, D.C., twice in campaigns climaxing in the battles of Antietam (September 17, 1862) and Gettysburg (July 13, 1863). Boundary between Maryland, Virginia, and West Virginia at Harpers Ferry, Satellite view of the Potomac River passing through two water gaps downstream of Harpers Ferry.
