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. After Franklin, the South Branch continues north through the Monongahela National Forest to Upper Tract where it joins with three sizeable streams: Reeds Creek, Mill Run, and Deer Run. All leeches' bodies are composed of 34 segments. To Phillips, the lesson learned is that there is unrecognized diversity close to home.. The river's two branches converge just east of Green Spring in Hampshire County, West Virginia, to form the Potomac. Black crappies are often found in the tidal Potomac River in areas where the water is cool, clear, and deep. In fact, they are quite shy and spend most of their time burrowed under soil and leaf litter (theyre fossorial snakes).

TREAT: Though the fact that copperheads are skilled hunters is a bit frightening, what makes them such precise predators is quite cool. In addition to stocking the river with more than 22 million shad fry, the Project supervised the construction of a fishway that was built to facilitate the passage of adults around the Little Falls Dam on the way to their traditional spawning grounds upstream. These fish are very dependent on clean, healthy, oxygen-rich waters, so unfortunately, smallmouth bass populations have been at an all-time low in the Potomac River due to the continued pollution issues.

[21][22], An average of approximately 486million US gallons (1,840,000m3) of water is withdrawn daily from the Potomac in the Washington area for water supply, providing about 78 percent of the region's total water usage, this amount includes approximately 80 percent of the drinking water consumed by the region's estimated 6.1 million residents.[5][23]. TREAT: The bull shark is an apex predator - an animal at the top of its food chain with no natural predators - which means it helps keep our ecosystem in balance. Hagemann, James A.

[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. When leeches bite, they inject an anticoagulant called hirudin. Yes, thats terrifying. This species is generally nocturnal, so they will hunt during the night for small fishes, crustaceans, and insects. I bought them in Minnesota when I lived there, he said. This species is generally piscivorous and will hunt for other fishes at night. 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. The South Branch is 130 miles long and originates near Hightown in Virginia. Remove and hold, returning any that try to crawl away to the pan. Below are the most common fish species found in the Potomac River today. Like the other snakes in the pit viper group, copperheads have heat sensory pits on either side of their head, between their eye and nostril, that allow them to detect minute temperature differences in their surroundings. 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. 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. Sad, that.

Wading into the water, she checked rocks and submerged wood scraps for leeches to collect and analyze. Pond Informer is growing community of pond & lake professionals, ecologists, and scientific writers, with a passion for all things ponds, wetlands, and sustainable conservation. 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. This species exhibits sexual dimorphism, so the males tend to be larger and darker than the females. The River Queen operated until the 1960s. . | Started in 1785 on the Virginia side of the river, it was not completed until 1802. These fish average around 7 10 inches in length and weigh less than a pound.

[35] Since then, the river has improved with a reduction in nutrient runoff, return of fish populations, and land protection along the river. The source of the South Branch is located near Hightown in northern Highland County, Virginia. 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. The river itself is at least 3.5 million years old,[6] likely extending back ten to twenty million years before the present when the Atlantic Ocean lowered and exposed coastal sediments along the fall line. Fish and Wildlife Service. TRICK: Walking through the woods on a summer day requires extra focus to make sure you do not accidentally crush a Death Adder underfoot.

Okay, this is more of an acrobatic trick, but these eight-legged friends jump to capture their prey. They are attracted to water disturbance around docks and swimming areas. Are there sharks in the Potomac River? On hot summer days leeches are most active.In winter they burrow in mud just below the frost line. 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. North of the confluence of the South Branch with Smith Creek, the river flows along Town Mountain (2,848ft) around Franklin at the junction of U.S. Route 220 and U.S. Route 33. They are venemous.
