Though you should definitely exercise caution around bull sharks, remember that humans pose a much greater threat to sharks than they do to us through hunting and water pollution. Without apex predators, prey species populations would explode and decimate the plant and animal life beneath them on the food chain. [35] Since then, the river has improved with a reduction in nutrient runoff, return of fish populations, and land protection along the river. As their name suggests, bull sharks are big and quite aggressive. Leeches can only reproduce sexually, and unlike some worms, they are not capable of regeneration. 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.

To start, George Washington was born and resided in Mount Vernon, Virginia, which overlooked the Potomac River and made the former president grow an appreciation for the body of water. While the park does not offer swimming facilities or overnight accommodations, its amenities include a picnic area, a playground, canoe, kayak and . All leeches' bodies are composed of 34 segments. Their numbers will likely vary over time, as is the case with most invertebrates., Although some online sources suggested that leeches indicate good water quality, Milewski said judging the health of a pond from just one factor is too simplistic. Despite looking like a frail skeleton with whiskers, these fish have staying power. [10] Native Americans had different names for different parts of the river, calling the river above Great Falls Cohongarooton, meaning "honking geese"[11][12] and "Patawomke" below the Falls, meaning "river of swans".

[31], In 1940 Congress passed a law authorizing the creation of an interstate compact to coordinate water quality management among states in the Potomac basin. Below are the most common fish species found in the Potomac River today.

The Potomac River then flows past Maryland farmland before dropping 77 feet within one mile at the boulders of the Great Falls. They are usually black or brown, although some species are brightly colored. TREAT: Though the fact that copperheads are skilled hunters is a bit frightening, what makes them such precise predators is quite cool. [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. Wading into the water, she checked rocks and submerged wood scraps for leeches to collect and analyze. Snakeheads caught in most major Virginia river drainages - Potomac, Rappahannock, York and now James Rivers, and many reservoirs: Northern Snakeheads were discovered in Virginia in 2004 and may be found in the Potomac River almost anywhere - from above Great Falls downstream to Chesapeake Bay. As a result, the same group issued a grade of "B" for 2017 and 2018. 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. These fish come in three subspecies that have slightly different patterning and native ranges, but they will all have darker green or brownish backs that fade to light green sides and a whitish belly. [This is tough, because theyre already brown.] [42][43], A variety of fish inhabit the Potomac, including bass, muskellunge, pike, walleye.

The river's two branches converge just east of Green Spring in Hampshire County, West Virginia, to form the Potomac. After years of failed appeals within the Maryland government's appeal processes, in 2000 Virginia took the case to the Supreme Court of the United States, which exercises original jurisdiction in cases between two states. It ran from Georgetown to Thorny Point at the mouth of Aquia Creek, with daily stops at Alexandria. Around Saranac Lake, it seems while everyone knows someone whos had an encounter with a leech, the leeches are few and far between. 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. Currently, white perch populations are doing extremely well in the Potomac River with abundance exceeding the historic mean. 2.1) 2002; by Michael J Pinder (Author), Eastern Fence Lizard Sceloporus undulatus, Eastern Six-lined Racerunner Aspidoscelis sexlineata sexlineata, Northern Coal Skink Plestiodon anthracinus anthracinus, Common Five-lined Skink Plestiodon fasciatus, Common Mudpuppy Necturus maculosus maculosus, Eastern Hellbender Cryptobranchus alleganiensis alleganiensis, Jefferson Salamander Ambystoma jeffersonianum, Eastern Tiger Salamander Ambystoma tigrinum tigrinum, Red-spotted Newt Notophthalmus viridescens viridescens, Eastern Red-backed Salamander Plethodon cinereus, Northern slimy salamander Plethodon glutinosus, Valley and ridge salamander Plethodon hoffmani, Seal Salamander Desmognathus monticola monticola, Northern Dusky Salamander Desmognathus fuscus, Allegheny Mountain Dusky Salamander Desmognathus ochrophaeus, Northern Red Salamander Pseudotriton ruber ruber, Eastern Mud Salamander Pseudotriton montanus montanus, Northern Spring Salamander Gyrinophilus porphyriticus porphyriticus, Northern Two-lined Salamander Eurycea bislineata, Southern Two-lined Salamander Eurycea cirrigera, Long-tailed salamander Eurycea longicauda longicauda, Four-toed Salamander Hemidactylium scutatum, Northern Spring Peeper Pseudacris crucifer, Mountain Chorus Frog Pseudacris brachyphona, Eastern Cricket Frog Acris crepitans crepitans, Northern Leopard Frog* Lithobates pipiens*, Southern Leopard Frog Lithobates sphenocephalus utricularius, Northern Green Frog Lithobates clamitans melanota, Eastern spadefoot toad Scaphiopus holbrookii, Eastern American Toad Anaxyrus americanus americanus, Eastern Narrow-mouthed Toad Gastrophryne carolinensis, The Potomac River watershed covers the District of Columbia and parts of four states, Confederate troops crossing the fords of the Potomac in early September 1862 for the invasion of Maryland, which would culminate in the, Union defenses along the Potomac near Washington, DC.

Females actually prefer to lay their young in fresh water habitats so will swim up into bays and rivers to do so before returning to the ocean to hunt larger prey (such as large fish, dolphins, crustaceans, turtles, and even other sharks.) 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. A medicinal leech is attached to the skin. Add more butter and olive oil. 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. 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. Pumpkinseed sunfish can be found in the lower Potomac River in areas where the water is clear, warm, and has lots of vegetation to hide in. 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. 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. 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. Striped bass are a larger fish that can grow to about 2 3 feet in length and weigh between 10 30 pounds.

Bull sharks are unique in that, though they live mostly in saltwater, they can tolerate freshwater. The Potomac runs through the Great Falls and then funnels downstream through the narrow Mather Gorge. 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. Started in 1785 on the Virginia side of the river, it was not completed until 1802. Add hot peppers or sauce to taste. [41], The original charters are silent as to which branch from the upper Potomac serves as the boundary, but this was settled by the 1785 Compact. Again standard bass tackle is recommended.
