Abstract
The water resources of the Los Coyotes Indian Reservation, San Diego County, Calif., are sufficient to supply the limited domestic and stock-water needs of the present residents of the reservation. Surface-water runoff is derived from direct precipitation on the area and from intermittent spring flow. Groundwater occurs in the alluvial deposits and in the consolidated rocks where they are highly fractured or deeply weathered. The best potential for groundwater development on the reservation is in the small alluvial basins in the San Ysidro and San Ignacio areas. Most water on the reservation is good to excellent in chemical quality for domestic, stock, and irrigation use. Water from two wells (and one spring), however, exceeds the primary drinking-water standard for nitrate plus nitrate. (USGS)
