There are dirt roads that provide access to almost the entire perimeter of the lake. There is a 15-mile per hour (24 km/h) speed limit, as the roads are bumpy and vehicles kick up a lot of dust, even at slow speeds. In addition, many visitors park on the side of the road to fish. The default speed limit on the lake itself is 5 miles per hour (8 km/h), but boats can travel up to 30 miles (48 km/h) per hour in certain areas, depending on conditions.
There is a proposal to raise the dam by 19 feet (8 m) with the addition of a spillway gate, which was part of the original design. The loss of trees from the additional capacity has been a major concern. In the area to be flooded there are 1,639 coast live oaks, 633 blue oaks, 198 valley oaks and 469 gray pines. The loss of oak trees is of ecological concern, since oak trees in the area are already contending with sudden oak death.
