ABSTRACT: Barriers that block upstream movement of adult sea lamprey remain the most effect tool in the control of this invasive species. Barrier infrastructure, along with public support to maintain it, continues to decline. As a result, connectivity projects that yield the most economic, ecological, and social benefit need to be strategically targeted. The Great Lakes Fishery Commission (GLFC) is keenly interested in fish passage solutions that consider both native fish production and invasive species control. Recently, the GLFC has embarked on several new partnerships and initiatives to assist with coordination of connectivity projects within the Great Lakes Basin and to develop new bi-directional fish passage technologies. To ensure integration of sea lamprey control requirements, the GLFC, in collaboration with the Great Lakes Commission, has recently developed a web mapping application to inform decision makers considering barrier removal scenarios. The application is built as a platform for decision making regarding sea lamprey control investments, natural resource management, and barrier removal for native species connectivity. The tool is available online at http://data.glfc.org/. The application offers the ability to trace upstream or downstream along unified U.S. and Canadian stream data, terminating at both existing and user-input barriers. Thus, users can visualize impacts of potential barrier addition or removal from system and basin-wide perspectives. In addition to barrier physical attributes and locations, the tool also includes historical sea lamprey control data. Web users can experiment on the placement or removal of dams and then see, instantly, the effect these management actions. Additional enhancements are planned during 2016 including addition of the metrics considered in sea lamprey treatment planning as well as trapping locations and results. Other historical sea lamprey control attributes, such as historic and current infestation boundaries, will also be included.
