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.

About Detert Reservoir

This 162-acre reservoir, perched at an elevation of 1,047 feet, offers visitors unparalleled views of its serene waters framed by picturesque white rail fences. Though public access for activities like fishing and hiking is restricted, its storied history and the charming surroundings make it worth a visit for those exploring the California countryside. Detert Reservoir’s history is as captivating as its natural beauty. Originally part of the Guenoc land grant awarded back in 1845, the area was later developed by William F. Detert. Responsible for constructing one of the largest earthen dams in California at the time, Detert’s legacy lives on in the reservoir that bears his name. The dam successfully harnessed Bucksnort Creek to create this tranquil lake, which once provided vital irrigation to the expansive pastures of Guenoc Rancho. Although the reservoir isn’t open for typical recreational activities, its allure lies in its untouched natural beauty and historical significance. The drive along Butt Valley Road, with glimpses of this secluded lake, offers a peaceful escape and a chance to appreciate the historic landscapes of Northern California's wine country.
