<br />Lake Granby storage would be lowered to 399,000 acr.e-feet (Elevation 8259) by
<br />the end of April and refilled to capacity (539,000 acre-feet - Elevation 8280)
<br />without spill by the end of July. Reservoir content of 529,000 acre-feet at the end
<br />of the water year would be 140 percent of normal.

<br />If most probable water supplies are forecast on February 1, planned early release
<br />of surplus river water to Nebraska from the North Platte System would be ne-
<br />cessary as protection against possible higher forecasts on March 1 or April 1.
<br />Planned releases from Guernsey Reservoir would average 1,600 c. f. s. during
<br />March and increase to 2,000 c. f. s. during April. In addition, a small owner-
<br />ship spill of 15,000 acre-feet would be made during May. The planned total
<br />release of 235,000 acre-feet would provide protection to the city of Casper,
<br />Wyo. , and prevent possible damage to structures and improvements on the North
<br />Platte River.

<br />Powerplant releases from Seminoe Reservoir would increase to 1,450 c. f. s.
<br />during February and March. Thereafter, the powerplant releases would be ad-
<br />justed as required to fill the reservoir (1,010,800 acre-feet) without spill by
<br />the end of July. Turbine releases for power generation averaging 1,100 c. f. s.
<br />during August and September would leave year-end reservoir stor,age well above
<br />norm:l1 at 901,000 acre-feet.

<br />Pathfinder Reservoir would reach maximum storage content of 928,000 acre-feet
<br />by the end of February. Thereafter, storage would be continuously reduced to
<br />meet downstream requirements. Fremont Canyon Powerplant releases would
<br />continue at 900 c. f. s. during February and increase to near capacity during
<br />March and April. The release schedule would refill Alcova Reservoir to the
<br />normal summer elevation and expedite the plalUled release of surplus river water
<br />to Nebraska. Thereafter, Fremont Canyon Powerplant release would be made
<br />as required to meet downstream irrigation demands without bypass. Reservoir
<br />storage of 563,000 acre-feet at the end of the water year would be much above
<br />the desirable normal.
