Therefore, accurate and up-to-date estimates of lake capacity are important for managing and predicting adequate water supply. Many of the water supply lakes in Missouri were previously surveyed by the U.S. Geological Survey in the early 2000s (Richards, 2013) and in 2013 (Huizinga, 2014); however, years of potential sedimentation may have resulted in reduced water storage capacity. Periodic bathymetric surveys are useful to update the area/capacity table and to determine changes in the bathymetric surface. From July 2019 to June 2020, the U.S. Geological Survey, in cooperation with the Missouri Department...

Major metropolitan areas present both direct threats, such as loss habitat and open space, and indirect threats, such as creating barriers to connectivity. As a result of both these direct and indirect threats, and their scale, metropolitan areas pose a challenge when thinking about corridors and connectivity, and many of the traditional approaches to green infrastructure and conservation are not adequate for urban areas. The Conservation Blueprint (Blueprint) is cross-boundary, cross-organization plan that prioritizes areas for shared conservation action in the South Atlantic.
