Poorly designed or failing road/stream crossings adversely impact rivers by altering essential stream processes or by acting as barriers to upstream movement. Throughout the Great Lakes region, there is an estimated 38 times more road crossings than dams and roughly two-thirds pose a threat to streams (Januchowski-Hartley et al. 2013). In 2013, CRWC initiated a watershed-wide road/stream crossing inventory to identify poorly designed or failing culverts. To-date, CRWC and trained interns have inventoried over 100 sites throughout 26 tributaries in the watershed.
