Capik is a privately owned earth dam located in Alturas, California, specifically in Modoc County. Completed in 1965, it serves primarily for flood risk reduction but also supports irrigation and water supply purposes. The dam has a height of 20 feet and a hydraulic height of 17 feet, with a length of 3510 feet and a storage capacity of 1367 acre-feet. It is situated on the Tr Nfk Pit Rv, within the Sacramento District of the US Army Corps of Engineers.

Despite being classified as having a low hazard potential, Capik has been deemed to be in satisfactory condition as of its last assessment in September 2017. It is regularly inspected by the California Department of Water Resources (DWR) as part of the state's regulatory framework, ensuring the safety and reliability of the structure.
