Hiked at the wonderful Peters Canyon Regional Park recently. Cloudy day, but it was still a pleasant hike overall. I was most interested in the Peters Canyon Reservoir. I have heard many stories of fishermen a long time ago catching largemouth bass and catfish out of it, but now there is no public access. This seems to be the case for many reservoirs and lakes in Orange County, a disappointing change from other parts of the country I have lived in.
Of note, the recent drought seems to have hit the reservoir particularly hard. It appears to be very shallow, and looked no more than a few feet deep from the shore. I wouldn't be surprised if most of the fish in Peters Canyon Reservoir have been eaten by herons or raccoon's.
