WHAT ARE RIVER MILES RESTORED?

River miles  restored refers to the recently reconnected stream miles that anadromous fish can navigate upstream after a project is completed until the next barrier in the system (ie, dams, or other obstructions to fish passage). River miles can be increased by removing dams, widening culverts, and constructing fish ladders, which are structures that allow fish to bypass a dam.

WHAT DOES THIS INDICATE?

This indicator tracks progress by the states and the Long Island Sound Study toward achieving river mile restoration goals.

STATUS

The original goal for river miles restored was 100 miles by 2008.  The goal was surpassed in 2006 and a new goal of 143 total miles by 2011 was established.  This new goal was surpassed in 2008, but a new goal has not yet been set.  As of 2015, the number of river miles restored is 335 miles.
