Drew Lake has a surface area of about 10 acres, and is entirely fed by run off from rainstorms. The shape is long and narrow, and depth usually is about 6-10 feet. Drew Lake is completely surrounded by private property, and no motorized boats are used on it.
In 1992 a drought dried the lake to a meadow like area, and that was the year of the famous Monterey Bay Area canyon aerial photograph. In the photograph it looks like an ellipse of green. After the drought, first mosquito fish and then non native bass fish were introduced to keep the mosquito population in check.
In the spring of 2016, Bluegill, Large Mouth Bass and mosquito fish were reintroduced into the lake after the water returned from the 2015 El Niño rains.
The lake has always had remarkable wildlife, including coyotes, bobcats, foxes, muskrats, racoons, opossum, blue herons, green herons, great egrets, seagulls, terns, Cormorants, Canadian geese, American White Pelicans, Eagles, red tailed hawks, shovelers, mallards, and two red throated snapping turtles. 20 years ago, the native Pacific Tree frogs were dense, but in the year 2000 non-native bullfrogs invaded. Now the native amphibians are almost extinct. Crawdads and small fish provide food for white pelicans and many kinds of ducks.
