CRP Photo Gallery - Aquatic Life Monitoring
USIBWC Texas Clean Rivers Program (CRP) participates in various aquatic monitoring events throughout the basin with sponsoring entities, including the Texas Commission on Environmental Quality and the Texas Parks and Wildlife Department. Biological monitoring is important to understanding impacts of water quality issues on the aquatic life of the river. Below are photos from the Dec 2010/Jan 2011 Upper Pecos River monitoring, the 2009 National Rivers and Streams Assessment, and 2009 monitoring in the Lower Canyons in the Wild and Scenic River below Big Bend National Park.
