We all live in a watershed

Our watershed is more than our creeks and streams, meadows and ponds. It’s part of all of us: the wildflowers and wildlife, birds and birders, fish and fishers, nature and nature-lovers.

What is a watershed?

Even if you live at the top of a mountain—or in the middle of an ocean—you probably live in a watershed. It’s a part of the planet where everything (fresh water, pollutants, sediment) drains towards a body of water.

As watersheds go, ours has a couple quirks. First, most watersheds drain into an ocean. Ours starts in a lake and ends in a lake (Tahoe to Pyramid). Secondly, our waters flow north and east—the opposite direction most watersheds west of the continental divide flow.
