Aquatic Connectivity Assessment and Prioritization Tool

Users in the North Atlantic region, from Maine to West Virginia, can use this site to help them identify bridges and culverts that impede aquatic connectivity.

A network of individuals from universities, conservation organizations, and state and federal natural resource and transportation agencies focus on improving aquatic connectivity across a 13-state region in the Northeast United States. This group uses common protocols for assessing road-stream crossings (culverts and bridges); they developed a regional database for storing and displaying the aquatic organism passability score derived from this field data. 

The NAACC supports planning and decision making by providing information about where restoration projects are likely to bring the greatest improvements in aquatic connectivity.
