Capacity to prioritize barrier removals in the Great Lakes basin is currently limited by lack of data on the passability of road crossings and dams for both unwanted invasive species and desirable native migratory fishes. Building upon our initial barrier inventory, this project has two key elements. First, we are testing whether our landscape statistical models accurately predict the upstream limits of fish migrations along the Wisconsin coast of Lake Michigan. This involves intensive field work to determine the actual upstream limits of suckers, pike, and steelhead during the spring migration. Second, we are collecting systematic data on the size and condition of dams throughout the Lake Michigan basin. These...

Ecological connectivity between the Great Lakes and their tributaries is widely impaired, and many agencies and organizations are currently investing in restoring these connections to enhance target fish and wildlife populations. To assist in targeting these investments, we have been developing spatial data on the location and attributes of barriers (dams and road-stream crossings) and fish breeding habitat throughout the Great Lakes basin to analyze the optimum strategy for enhancing connectivity and restoring fish migrations. The proposed work will result in guidance for barrier restoration at scales from individual watersheds to the entire basin, refine methodologies for spatial analysis of barriers, and provide...
