This morning’s dog walk was along the easy-to-walk water company road through the nearby Mt. Baldy watershed. The other end of this space is a large dam on the edge of a fully empty basin. It hasn’t rained enough in many years to fill even a tiny portion of the basin.
A watershed is an area of land that drains all the streams and rainfall to a common outlet such as the outflow of a reservoir, mouth of a bay, or any point along a stream channel. The word watershed is sometimes used interchangeably with drainage basin or catchment. Ridges and hills that separate two watersheds are called the drainage divide. ~ U.S. Geological Survey Water Science School
