The Willow Creek watershed is adjacent to the Santa Maria <br />watershed, is simi 1 ar in shape and area, and both have a southerly <br />orientation. The gaging station on the Rio Grande at Del Norte provi- <br />des an accurate description of the entire basin yield and indications <br />of droughts, wet years and trends. Since monthly and annual discharge <br />volumes were necessary, data compiled by the Colorado Climate Center, <br />Department of Atmospheric Science, Colorado State University was also <br />util i zed to estimate streamfl ow (7). The cal cul ated average annual <br />volume of water available at the Santa Maria feeder canal diversion <br />point is approximately 27,000 acre~feet but can exceed 45,000 acre- <br />feet during wet years. <br /> <br />b. Continental Reservoir Inflow <br /> <br />There are no gagi ng stati ons upstream of Conti nental Reservoi r, <br />nor any records of reservoi r i nfl ow. The USGS gage on North Cl ear <br />Creek is about 1,000 feet below the dam with no intennediate tribu- <br />taries and no upstream diversion. Flow at the gaging station is regu- <br />lated by Continental reservoir and the outlet. <br /> <br />Hi stori c reservoi r storage records are avail ab 1 e for Conti nental <br />Reservoir and were obtained from the State Engineers office. Records <br />prior to 1964 were unava il ab 1 e, however. The monthly ; nfl ow to the <br />reservoir was calculated from the monthly records using the fonnula: <br /> <br />Net Inflow = Total Outflow + Change in Storage. <br /> <br />IV - 5 <br />
