When I left the park at 6:15 there were 4 Bonaparte's gulls near the shore - 1 @ the mouth of the marina, 2 off the 'stone beach' and 1 straight ahead from the parking lot on the lake. Also 2 Fox Sparrows, a Towhee, a Field Sparrow, 10+ Northern Rough-winged Swallows, Hermit Thrush, and Kingfisher. 1 Iceland gull and horned and red-necked grebes in the marina.
