The Virginia Trout Stream Sensitivity Study collects data on brook trout streams in the Commonwealth.
The VA Tout stream sensitivity study also has a webpage. The Virginia Trout Stream Sensitivity Study (VTSSS) is designed to track the effects of acidic deposition and other factors that determine water quality and related ecological conditions in Virginia’s native trout streams.
The VTSSS 2010 survey will be the third regional survey conducted with the assistance of Trout Unlimited and other volunteer organizations. Previous surveys were conducted in 1987 and 2000. Following the first survey, a geographically distributed subset of streams was selected for long-term monitoring. This component of VTSSS now includes 67 streams that have been sampled on a seasonal (quarterly) basis for 24 years.
