Water defines us. It’s the reason we call our region the WBay Area. It shapes the Peninsula and sculpts the land. It cleans the air. It comes down from the sky as rain and fog, and comes up from the earth via springs and aquifers. It makes up more than 70 percent of most living things. Beach Bubbles © 2003 Dan Quinn Land carries the water, but water makes the land come alive, coursing through the earth and giving it health and vitality. Watershed protection has long been a priority at POST, and by helping us save open space, you preserve the natural systems found there, including critical water resources that nourish and sustain us. Connecting Land and Water There are 16 major watersheds in the 63,000 acres POST has saved since its founding in 1977.

Conserving Land, Protecting Water San Gregorio Farms © 2002 POST SPOTLIGHT: San Gregorio Watershed
The San Gregorio watershed is one of 34 distinct drainages in San Mateo County. POST-protected lands help form a buffer around TSan Gregorio Creek and its tributaries, so threats to the watershed are eliminated or significantly reduced. Water for drinking, plant and animal habitat, agriculture and Ripples © 2009 David Hibbard recreation is best when its cycle of descent, accumulation and return takes place on undeveloped land. On POST properties, no massive development projects, dumping or grading occur and no sand, gravel or minerals are mined. In short, activities that POST Projects in the might impair the quality of water on POST-protected land are prohibited.

A Water Droplet’s Point of View
Watersheds are complex natural systems, but when it comes right down to it, they all start with a single drop of water. By tracing the droplet’s Wjourney from its origins to the sea and back again, we get a better sense of the water cycle and how we must protect entire landscapes to protect watersheds. Take the San Gregorio watershed, where POST and our conservation partners have saved nearly 16,000 acres for local agriculture, wildlife and recreation. If you were a water drop here, you’d make a trail from Skyline
