Prioritizing Crossings for Assessment
The NAACC has completed a HUC12 subwatershed prioritization to help identify subwatersheds that may be higher priority for field survey.
The prioritization included criteria such as diadromous fish, brook trout, likelihood of crossing failure, greater uncertainty of crossing passability, and impact of crossing failure.
The results of the prioritization, which may be viewed for the entire NAACC region or stratified by state, are displayed on a web map (click on image below) and can be explored through use of a customizable tool (downloadable here) for use with ArcGIS Desktop.
Please contact Erik Martin with any questions about this prioritization.
