Additional Information
When the result of the Create Watersheds tool is not as expected (for example, disconnected polygons or oddly shaped watersheds), the most likely reason is that the point provided does not fall on a location with high accumulation flow. To define a hydrologically correct watershed, it is necessary to snap the given point to a location of high accumulation flow. Therefore, it is recommended to use different reasonable search distances.Workaround
Use a reasonable search distance to snap the point to a high flow accumulation location. For example, for the case provided use a search distance of 1000 meters.
