My input surface is from Topo To Raster (Type: File Geodatabase Raster Dataset), but when I want to use Raster--> Project, it doesn't let me to choose the Raster file as Input Dataset or Feature Class (The Raster file is not shown_attached screenshot). Do I need to convert the Topo To Raster to a different format first?

Hi, I finally managed to create DEM from bathymetry points and calculate the volume, but the output does not make sense. I guess I need to modify the units or coordinates. I don't know how. Here is the output (My input surface is the elevations of the bed in meters above sea level (m asl) in GCS_WGS_1984 and decimal degrees and my Plane Height is the reservoir full supply level (FSL) which is 556.87 m asl: Plane_Height, Reference, Z_Factor, Area_2D, Area_3D, Volume 556.87, BELOW, 1.00, 0.053866900608273, 126.88623569244, 1.3850421777189

Hi, I would like to create a bathymetry map (DEM) and calculate the volume for a large riverine reservoir (Lake Diefenbaker). I have the bathymetry depth points. The first issue is how can I restrict the interpolation area to the shoreline areas? Because points are along the river valley which it divides into a fork at the end (T shape reservoir, attached photo), I can’t simply create a TIN surface without creating a boundary around. Could anyone provide me with a workflow from POINTS --> Bathymetry map (DEM) and the reservoir Volume? Thanks
