<br />LITTLE THOMPSON RIVER - Boulder, Larimer, and Weld <br />Counties, Colorado. The river, thoughout this reach, is <br />characterized by a meandering channel flowing through a "V" <br />shaped valley, surrounded by irrigated cropland. The <br />qual ity of the water in the study area is poor primarily due <br />to return flows from the reuse of irrigation water. Also <br />there are large amounts of trash on the streambanks. The <br />study area consists of 12 sites for a total of 82,232 feet <br />(15.57 mi les) of stream. The 1055 of riparian areas, <br />damage to irrigation structures, and damage to bridge <br />embankments are examples of types and extent of damages. <br /> <br />The proposed measures for improvement included rock <br />riprap, anchored trees, rock jetties, jacks, vegetated <br />buffer strips, vegetative sprig revetment, and riparian <br />zones. The water qual ity can be improved with "Best <br />Management Practices." <br /> <br /> <br />Streambank erosion into cropland on Little Thompson River <br />Photography by Jim Thornton, SCS, Denver, Colorado <br /> <br />32 <br />
