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. Hirudin is injected by the leech upon puncturing its victim's skin with its sharp jaws, and it acts to prevent the blood from clotting, thus enabling a continuous flow of blood for the leech to suck on. The Donning Company, 2nd edition, 297 p. District of Columbia Water and Sewer Authority. Are sturgeons returning to our waters decades after disappearing? An international collaboration investigating biodiversity in leech populations led Phillips, a curator of parasitic worms and invertebrate zoology at the National Museum of Natural History, to streams and ponds across the eastern United States. This created conditions of severe eutrophication. Today, the species - which is found throughout the eastern United States - are further threatened by commercialization of their caves, loss of their wooded summer habitat, pesticides and water contaminants, and white nose syndrome. Once youve trapped the leeches, you can use them as bait or dispose of them otherwise. Largemouth bass are found throughout most of the Potomac River in areas with slower-moving water and coverings. Since then, there have been several efforts to help minimize contamination and protect the wildlife in the Potomac River.

White crappies have compressed bodies that are silvery-olive on the back and silvery-white towards the belly. One dam was to be built at Little Falls, just north of Washington, backing its pool up to Great Falls. Bluegills are a main source of food for many larger fish such as largemouth bass, so they have adapted to be maneuverable. That means that they can accurately strike a prey animal just by sensing its body heat. 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. (Enterprise photo Glynis Hart), Milewski pointed out that not all leeches are parasitic bloodsuckers.

The researchers first needed to understand whether the unusual parasites were confined just to Southern Maryland or had a larger habitat. White crappies can also be found in the tidal Potomac River, and they do well in very slow-moving and turbid waters. First, leeches in ponds should be expected, said Milewski. These fish grow to be about 5 - 8 inches long and weigh around 8 - 12 ounces. The sandy beach, moving water and wave action at Lake Colby dont make for a good leech habitat.

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. [25] Several other dams were proposed for the Potomac and its tributaries. The results of the DNA analysis, however, prompted them to give the specimens a closer look. Adjust salt carefully, because the leeches get as snotty as the okra if over-salted. In fact, they are quite shy and spend most of their time burrowed under soil and leaf litter (theyre fossorial snakes). With a close inspection, the researchers noticed a subtle difference in the spacing of the leeches accessory pores. [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].
