I downloaded LiDAR data as a .tif and brought it into a clean map. I can use almost every Hydrology tool i.e. build the Flow Direction and Accumulation, yet once I develop Pour points and go to input my raster into the actual Watershed tool every raster I have generated returns the same error as soon as you input it into the tool. its error 000864:&lt;value&gt;: The Input is not within the defined domain. &lt;value&gt;.&nbsp; How do i fix this? What am I doing wrong?</P> Thu, 15 Dec 2022 16:17:56 GMT https://community.esri.com/t5/arcgis-pro-questions/watershed-tool-returns-error-000864/m-p/1241584#M63473 WetlandMan 2022-12-15T16:17:56Z https://community.esri.com/t5/arcgis-pro-questions/watershed-tool-returns-error-000864/m-p/1241600#M63478 <P>Good morning!&nbsp; There's a Tech Support article <A href="https://support.esri.com/en/technical-article/000011393#:~:text=%22000864%3A%20The%20input%20is%20not%20within%20the%20defined,to%20polygons%20is%20available%20on%20ArcGIS%20Web%20Help." target="_self">here</A> that describes the error code and how to fix it.&nbsp; Likely a floating point bit depth issue.</P> Thu, 15 Dec 2022 16:52:59 GMT https://community.esri.com/t5/arcgis-pro-questions/watershed-tool-returns-error-000864/m-p/1241600#M63478 Robert_LeClair 2022-12-15T16:52:59Z
