Road-Stream Crossing Assessments

Starting in the 2020 field season, PRWC began surveying road-stream crossings in the Pomperaug Watershed following protocol from the North Atlantic Aquatic Connectivity Collaborative (NAACC). PRWC participates in the assessment of road-stream crossings for
non-tidal streams and rivers using NAACC's data collection forms and training materials.

Aquatic life passage is difficult and sometimes impossible when streams and rivers and fragmented by inadequate stream crossings. Through these assessments, data collected by field assessors are submitted to NAACC and processed to be classified and listed in their database. This helps provide mapped information on culverts, bridges, or crossings that may need to be prioritized for repair or replacement to improve the connectivity of the stream or river.
