An excellent spot to take a break and enjoy the full breath of Lexington Reservoir. There is a Plaque dedicated to deputy Douglas B. Miller, who was fatally wounded while performing his duties.

From the top of the dam you get splendid views out across Lexington Reservoir. To the north you overlook the winding end of the Los Gatos Creek Trail, which connects to the Jones Trail across from the restroom just up the road. The dam itself was constructed in 1952 and stands at nearly 200 feet tall.
