National Register of Historic Places in Alameda County
Established March 18, 1870, this is America's first official wildlife refuge. Now in the heart of Oakland's business district, the 160 acre salt water lagoon provides sanctuary for migratory birds under somewhat adverse conditions. Thousands of wild ducks winter here, attracted by the food and shelter available on the lake.
