Sequoia is a privately owned dam located in Richland, Wisconsin, designed by USDA NRCS and completed in 1973. This Earth-type dam serves multiple purposes, including fire protection and providing a small fish pond. With a structural height of 26 feet and a length of 350 feet, Sequoia has a storage capacity of 40 acre-feet and a drainage area of 0.4 square miles. The dam's spillway type is uncontrolled, with a maximum discharge rate of 65 cubic feet per second.

Despite being classified as having a low hazard potential and fair condition assessment, Sequoia poses a moderate risk, with a risk assessment rating of 3 out of 5. The dam is regularly inspected, with the last assessment conducted in May 2020. While no emergency action plan (EAP) is currently in place, the dam meets regulatory guidelines for inspection, enforcement, and permitting by the Wisconsin Department of Natural Resources. In the event of an emergency, the dam's owner and local authorities will need to take appropriate risk management measures to ensure public safety and minimize potential impacts on the surrounding area.
