Reviews of Lake Detert reservoir

Beautiful area. Some good boondocking sites.

Beautiful Reservoir right along the Highway, but no access allowed for fishing, hiking or anything. The white rail fencing is nice. More information about Detert Reservoir: Jeff and I took a weekend country side drive in the hills of Solano, Napa and Lake counties to locate and discover some area lakes. Detert Reservoir is a 162 acre reservoir at an elevation of 1,047 feet above sea level is located in Coyote Valley 5.2 miles east of Middletown, 19 miles southeast of Clear Lake, near Mirabel (historical), CA. This reservoir lies in a beautiful picturesque valley right on Butt Valley Road and is lined with white three railed ranch fencing. Back on August 8, 1845 the Mexican Governor of California, Pio Pico, awarded a land grant to George Rock and that Grant was called GUENOC. This huge land grant encompassed over 21,220 acres of this part of the country. George Rock lived on the property until his death, several settlers established themselves on the granted property and one of them William F. Detert. He was responsible for using his wits, power and money to form the land holdings that would encompass nearly the identical number of acres and a large percentage of the same land as the original Grant. William F. Detert named his land holdings; Guenoc Rancho. The reservoir was named after William F. Detert whose most significant accomplishment at Guenoc Ranch was the building of, what was considered to be at the time, the largest earthen dam with a rock core in California. He did this in about 1925 and most of the earth moving was done with teams of horses. The dam and reservoir that bears his name, “Detert”, successfully dammed “Bucksnort Creek” forming a lake encompassing about 120 acres holding 1300 acre feet of water. This reservoir was the water source for the remainder of the project which was the underground piping to several hundred acres of pasture in the valley. The piping was concrete and came from the concrete works in St. Helena.

Beautiful place.
