<br />Missouri River, Cyclic reservoirs filled, and several spilled during
<br />the season, Substantial flood control was provided by several system
<br />reservoirs especially Boysen and Glendo, Generally, the water supply
<br />was adequate to meet all irrigation demands. All projects improved
<br />their storage water reserves during the year. Lack of demand for
<br />irrigation water did materially limit system generation during the
<br />summer. It was necessary to release additional water in several
<br />areas to control loading on transmission lines. This was especially
<br />true when Yellowtail was generating at full capacity. Above normal
<br />irrigation demands late in the season did adequately evacuate storage
<br />in terminal reservoirs, System generation will be somewhat limited
<br />this winter, but energy remains readily available from the Eastern
<br />Division System. Generally, the Western Division System was very
<br />successfully operated during Water Year 1967,
<br />
<br />Seasonal runoff of the Blue River above Green Mountain Reservoir was
<br />80 percent of average, The reservoir was filled on schedule and the
<br />Cities of Denver and Colorado Springs obtained about 70,000 a.f, of
<br />water during the season, Inflow to Willow Creek Reservoir was
<br />slightly above average, Over 45,000 a.f, of water was available for
<br />pumping to Lake Granby during the season, Seasonal inflow to Lake
<br />Granby was normal, but carry-over storage remained well below
<br />average, Although the runoff of the Big Thompson River was less
<br />than 90 percent of average, skim at Lake Estes was near normal
<br />totaling nearly 42,000 a,f, There was virtually no irrigation
<br />delivery to Colorado-Big Thompson users until late in July, Delivery
<br />thereafter was above average especially during August. Seasonal
<br />irrigation delivery for the water year totaled 198,000 a,f, compared
<br />to the ten-year average of 226,000 a,f. Carry-over storage in
<br />Carter Lake and Horsetooth Reservoir was above normal at the end
<br />of the year, Project storage reserves increased by about 55,000 a,f,
<br />during the season, Seasonal inflow to Seminoe Reservoir was normal
<br />during Water Year 1967, Runoff was very slow to develop causing
<br />reservoir storage to drop below plan early in May, With limited
<br />downstream demand for water, carry-over storage at the end of the
<br />year was greater than anticipated but remained below average,
<br />North Platte River gains below Seminoe Dam were well above normal
<br />during the season, Total irrigation delivery to the Kendrick
<br />Project of about 48,000 a.f. was below average. Heavy precipitation
<br />over the Lower North Platte Valley caused exceptional gains below
<br />Alcova, High river gains and limited irrigation demand caused the
<br />North Platte Project storage ownership to fill, This allowed the
<br />Kendrick Project to accrue about 90,000 a,f, of water during the
<br />season, Total delivery to the North Platte Project was 870,000 a, f.
<br />compared to a normal requirement of 1,050,000 a,f. With heavy summer
<br />precipitation, reservoir inflows were well above normal in the
<br />Bighorn area, Boysen Reservoir filled and spilled with the maximum
<br />April-July runoff since 1924, Flood damage prevented by regulation
<br />at Boysen Reservoir was estimated at 6,8 million dollars, Seasonal
<br />inflow to Buffalo Bill Reservoir was over 120 percent of average,
