The drainage above the project area has steep, rocky slopes and <br />rapid runoff results from torrential rains. The mountain snow, melting <br />in the spring, usually produces a high sustained flow. From about May to <br />October intense rains occur frequently and produce floods of considerable <br />peak and volume. Runoff from rain floods seldom lasts more than a few <br />days ~ <br />80. The total flow of the Purgatoire River at Trinidad is adequate <br />for the 19"OO irrigated acres in the project area if controlled and re- <br />duced to a divertible rate of now. The existing erratic flows result in <br />considerable diversion in excess of immediate requirements during periods <br />of hiGh streamflow and lengthy periods of shortage during low streamflow <br />periods. <br />8l. A gaging station has been maintained at Trinidad since l896, <br />but records are complete only since 1916. An automatic recorder was <br />placed in operation in 1922. Discharge records are available in the <br />Biennial Reports of the Colorado State Engineer and in U. S. Geological <br />Survey:/ater Supply Papers. Other Purgatoire River records available <br />
