Explore Your Watershed ...

Explore the Prettyboy using this map. The watershed boundary is indicated by the purple circle.  Rain (or snow) that falls inside the circle ends up in the Prettyboy Reservoir. If you click on the icon in the upper right (four arrowheads) you will get a full screen view.  Click on the vertical blue "Features" bar and you can select your choice for map layout (one of the four "base layers").
