Interactive Watershed Map

This is an interactive map showing our watershed and neighboring watersheds. The Oswego Lake Watershed has a light blue overlay, and the two neighboring watersheds are Tryon Creek (yellow-green overlay) and the Tualatin (pink overlay).

The solid green shapes on the map indicate all the areas where we have worked in the watershed – past projects are light green, current projects are darker green. Click on these solid green shapes for more information about our projects.
