Surveyors Valley in Modoc, California, is a Federal-owned dam with a primary purpose of fire protection, stock, or small fish pond. Built in 1955 by the USDA Forest Service, this earth dam stands at 8 feet tall and stretches 425 feet in length, with a storage capacity of 925 acre-feet. The dam's spillway is of the controlled type, measuring 15 feet in width, and its outlet gates consist of a slide (sluice gate) mechanism.

Despite being classified as having a low hazard potential, Surveyors Valley poses a very high risk due to its location and surrounding conditions. The dam has not undergone a recent condition assessment, with the last inspection conducted in 2010. However, it is part of the risk management plan under the Forest Service's jurisdiction. With its strategic purpose and historical significance in the region, Surveyors Valley serves as a vital water resource for maintaining ecological balance and supporting local wildlife populations in the area.
