ABSTRACT: Within the St. Clair-Detroit River System (SCDRS), fish and wildlife habitat and water quality have historically been degraded, however in 2004, extensive restoration projects began on this system to remediate past degradation. Post-monitoring of restoration areas conveys improving biota of the region, including improvement in Burbot, Lake Sturgeon, Walleye, and Lake Whitefish. Although species are improving in the region, the response of anglers in the region remains unknown. In 2002-2005, an extensive creel survey was conducted, however, since that time, there has been no other extensive analysis of the anglers in the SCDRS. We analyzed post-restoration creel data by calculating interview catch rates, interview harvest rates, and examining supplemental questions collected by the Michigan Department of Natural Resources (MDNR). We also estimated the economic value of a recent creel survey by using estimated lodging and gas expenses of interviewed anglers in the SCDRS. We examined interest in fishing in the SCDRS by examining Google Trends data. For Lake St. Clair and the Detroit River, there were larger interview catch and harvest rates in post-restoration periods than in pre-restoration periods. We determined that the 2017 open water fishery on Lake St. Clair was worth approximately $11.87 million. Search terms related to the Detroit River and show a significant upward trend, indicating a rise in fishing interest in the region. Because of the increased travel, interview catch, interview harvest rates, and interest in Lake St. Clair and the Detroit River, anglers are likely capitalizing on increased fishing opportunity in these parts of the system. Another extensive creel survey, similar to the one conducted in the early 2000s, would be helpful in further determining the influence of restoration on angling opportunities in the SCDRS and if anglers are acting to remediate restoration costs.
