This map depicts the Rivers and Streams Conservation Asset for Florida with road barriers from the Southeast Aquatic Barriers Tool. The number of miles that could be gained through conservation action to remove obstructions are summarized by HUC12 watershed units. River/Stream Connectivity is an ecological indicator for the Landscape Conservation Project for Florida. The project entails a large-scale assessment of and planning for the health of important natural resources, known as Conservation Assets (CAs), in Florida. Conservation planning at the landscape scale provides a framework for safeguarding functional ecosystems, and their interconnected processes necessary to achieve true preservation of healthy resources....

The Passage Assessment Database (PAD) geospatial file contains locations of known and potential barriers to salmonid migration in California streams with additional information about each record. The PAD is an ongoing map-based inventory of known and potential barriers to anadromous fish in California, compiled and maintained through a cooperative interagency agreement. The PAD compiles currently available fish passage information from many different sources, allows past and future barrier assessments to be standardized and stored in one place, and enables the analysis of cumulative effects of passage barriers in the context of overall watershed health. The database is set up to capture basic information about each...

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...

Mapping of barriers and statistical prediction of their passability is now fairly complete in the Great Lakes basin, yet field assessments of barrier characteristics and passability to migratory fishes are spotty. We will use the Lake Michigan basin as a pilot area for comprehensive field assessment of dam condition, dimensions, and passage technologies. These characteristics will be incorporated into our barrier database, enabling improved estimates of removal costs, watershed cumulative passability, and infrastructure maintenance challenges. In parallel, we will conduct field assessments of passability to spring migrations of Great Lakes fishes in 15 Wisconsin watersheds. Recording the upstream limits of migrations...
