A brook floater filter feeding as it is anchored into the sediment of a stream bottom. Habitat loss is a long-recognized problem for many endangered species, and the brook floater is no exception. In-stream alterations that change flow and alter sediment loads can affect downstream locations where freshwater mussels live.

Survey Requirements for Culvert Indirect Measurements - Culvert SurveyThis video describes the survey requirements for culvert indirect measurements, specifically how to measure various aspects of the culvert itself. This video provides a general overview of how to survey culvert attributes, such as the invert and length.
