A proposed massive road building project will, if constructed, bisect the Toklat Basin area along or adjacent to the old Stampede Trail. The road and its associated gravel pits will affect hundreds of pristine waterbodies, aquatic habitat, and wetlands. At particular risk are spring-fed gravel-bed streams which act as salmon spawning, rearing, and overwintering areas. A basic and severe lack of knowledge of the water resources along this corridor seriously threatens the NPS's ability to analyze, manage, and protect this area, and subsequently mitigate impacts if this road construction occurs. As a result, a comprehensive study was initiated to determine baseline water quality and physical hydrology information in the Toklat Basin. This report describes the preliminary investigations of water chemistry, watershed hydrology, and channel morphology for fiver drainages in the Toklat Basin, including the Sushana River, the East Fork River,Wig and Creek, the Toklat River, and the Clearwater Fork.
