I found this nice picture of Silverwood Lake on the California State Parks website. If you're planning a trip visit http://www.parks.ca.gov/?page_id=650 and make sure to click on the link to make a boat reservation (the link is on the right side of the page) since the weekends sell out in advance. I was stunned to find out that the boat line for the portion of the allotted boat spots given first come first serve sometimes starts to form at 11pm Friday night. Not a nice way to start your day on the lake if you ask me... so plan ahead and make a reservation.
