Arkansas fatmucket [Lampsillis powelli]

The Arkansas fatmucket is a medium sized freshwater mussel approximately 3.9 inches in length. Its shell is shiny olive-brown with a pearly, bluish-white interior. This species is found in deep pools or backwater areas with sand or gravel bottoms and a fast current to prevent silt or detritus buildup. The fatmucket, like other mussels, feeds by filtering food particles from the water and is sensitive to silt which clogs their feeding siphons.

The historic range of the Arkansas Fatmucket mussel was believed to have been widespread in Arkansas in the Caddo River, the Ouchita River, and the Saline River. However, it is now only found in select locations and in limited numbers in these three rivers. The decline of the Arkansas fatmucket has been attibuted to construction of dams, alteration of channels, gravel dredging, and other practices that have destroy the species' habitat. In addition, the regions water quality has suffered significant degradation by the runoff from mining operations, improperly treated sewage, fertilization, and other industrial and agricultural runoffs.

Leopard darter[Percina pabntherina]

The Leopard Darter is a approximately 3 inches long. This fish has dark eyes, a white belly, and a light olive back that is spotted with dark spots and saddles. This fish feeds on algae and small invertibrates and in riffles and shallow pools of fast flowing streams from mountainous or hilly terrains with rubble, boulder or bedrock bottoms. This fish is only found in the Little River basin in southeastern Oklahoma and in southwestern Arkansas.

The Leopard Darter habitat has been significantly altered by dam and reservoir construction on the Little River system. In addition, agricultural and industrial practices have been known to influence water quality essential for darter survival. The Fish and Wildlife Service (FWS) has designated protection ranges in the Little River in both Oklahoma and Arkansas, the Black Fork Creek, Glover Creek, including portions of east and west forks, and the main channel of the Mountain Fork Creek. Survival of this species depends on efforts to improve water quality and to protect and restore leopard darter habitat.
