The USGS National Water Dashboard (NWD) is a new mobile-friendly tool that provides real-time information on water levels, and weather and flood forecasts all in one interactive mapping application. Building on innovative work by the Oklahoma-Texas Water Science Center with the USGS Texas Water Dashboard that was launched in early 2016, the NWD represents the next step in the

In cooperation with the Grand River Dam Authority, in the summer of 2019 USGS surveyed the Grand Lake O’ the Cherokees, which is locally called Grand Lake and located in northeastern Oklahoma. The survey was conducted to prepare an updated bathymetric map and surface-area and capacity table. Due to the natural changes to the reservoir, new capacity and area tables are needed periodically. Capacity and area tables identify the relation between the elevation of the water surface and the volume of water that can be impounded at each water-surface elevation. This study (1) includes high-resolution multibeam bathymetric data, and (2) describes the methods used to collect and process the bathymetric data. The bathymetric map may serve as a baseline to which temporal changes in storage capa
