<br />water year 1965 was quite consistent over the entire system. With the <br />exception of the tributary inflow to the North Platte River between <br />A1cova and Guernsey Reservoirs, at 236 percent of average, other <br />reservoir inflows varied between 132 and 142 percent of normal. <br /> <br />The unusually high runoff'originating below A1cova Reservoir resulted <br />from cloudbursts during May and June. One of the storms produced near- <br />maximum record discharge above G1endo Reservoir and the third far <br />exceeded the previous maximum discharge of record at the Orin Junction <br />gaging station. The inflow during water year 1965 originating between <br />A1cova and Guernsey Reservoirs was far in excess of the reasonable <br />maximum inflow used in the Annual Operating Plan which historically <br />has been equaled or exceeded only 10 percent of the time. The annual <br />runoff above Buffalo Bill and Boysen Reservoirs was slightly in excess <br />of the reasonable maximum inflow that can be expected. <br /> <br />With the exception of the March 1 forecast for the Sweetwater River, <br />inflows to all reservoirs during the April-July period exceeded all <br />of the forecasts which are made monthly from February 1 through <br />July 1. <br /> <br />Due to above-normal runoff, many projects obtained there allotted <br />storage rights and several major reservoirs were filled. The G1endo <br />Unit, Guernsey and the ln1and Lakes all filled their allotted owner- <br />ship from inflows originating below A1cova. In addition, more than <br />100,000 acre-feet were bypassed to Lake McConaughy. The Pathfinder <br />ownership of the North Platte Project was filled and the Kendrick <br />Project obtained 7,000 acre-feet of storage water. Of the major <br />system reservoirs, Boysen, Buffalo Bill, G1endo and Green Mountain <br />fi11ea. A considerable amount of flood damage was averted by system <br />reservoirs, although most have no flood control space provided. <br />Although the undep1eted snowmelt inflow above Green Mountain Reservoir <br />was not the maximum of record, the maximum daily inflow would have <br />equaled or exceeded previous maximum inflows prior to construction <br />of Dillon Reservoir. The peak unregulated inflow in excess of 5,000 <br />c.f.s. was stored in Green Mountain Reservoir and Dillon Reservoir owned <br />and operated by the City of Denver. The maximum outflow from Green <br />Mountain Reservoir during the season was 1,640 c.f.s. In 1957, a <br />release of 3,000 c.f.s. washed out some fish ponds constructed in the <br />secondary channels below Green Mountain Reservoir. Without Co1orado- <br />Big Thompson Project reservoirs and City of Denver reservoirs in the <br />Colorado River Basin, the flow of the Colorado River above Grand <br />Junction would have been about 30,000 c.f.s. compared to 35,000 c.f.s. - <br />the maximum during the 32 years of record. Some flooding has occurred <br />in this area in recent years with lesser flows. On two occasions <br />during water year 1965 diversion of flows of the Big Thompson River <br />at Estes Park reduced flood damage. At Buffalo Bill Reservoir, the <br /> <br />ii <br />
