It joins the San Juan River in New Mexico <br /> <br /> <br />fourteen miles below the Colorado - New Mexico state line. <br /> <br /> <br />The watershed peaks rise to elevations of over 14,000 feet. This <br /> <br /> <br />high watershed provides reliable high yield runoff. River flow all <br /> <br /> <br />originates in Colorado and below the State line the river is a losing <br /> <br /> <br />stream. <br /> <br />River runoff is well controlled for seasonal use and carry-over <br /> <br />use by the Vallecito Reservoir, constructed by the Bureau of Reclamation <br />and piaced in operation in 1941. The Vallecito Reservoir has an active <br />storage capacity of 126,300 acre feet. The natural flow of Pine River <br />supplemented by storage of the Vallecito Reservoir provides a full supply <br />of water for lands under canals diverting from Pine River. Reservoir <br /> <br />releases serve both Indian and non-Indian land. Crops consist of alfalfa <br /> <br />hay, livestock pasture, grains and fruit. <br /> <br />Water Runoff <br /> <br /> <br />Datu on annual unregulated runoff of Pine River at the Vallecito <br /> <br /> <br />Reservoir is summarized in the following Table XIV. <br /> <br />-22- <br />
