water level fluctuation increased correspondingly. (See Figure

3.) As in Scenario A the reservoir was filled to capacity,

Elevation 5574, in three years (1949, 1952 and 1957) and had a

minimum level between Elevation 5557 and Elevation 5558 in three

years (1955, 1956 and 1957). During those three years the reser-

voir water levels were into the permanent pool a total of seven

months. The total water surface fluctuation was 17 feet.

Of the eight agencies involved with this scenario, four

agencies satisfied their commitment throughout the exercise

period. Of the other four, two (state and Lakewood) had

insufficient space for carryover, which resulted in shortages

later on, and the other two (Mt. Carbon and Englewood) had

insufficient inflow to meet evaporation ahd release requirements.

Five of the seven agencies with reserved space used 90

percent or more of their space for five or more years.

2.1.6 scenario C (Without Bookover) criteria and Assumptions

1. The objective of the operating plan is to keep the reservoir

contents between 1974 acre-feet (Elevation 5558) and 4599

acre-feet (Elevation 5576.20).

2. The permanent pool (1974 acre-feet) is full and individual

accounts in the flood control pool are empty at the begin-

ning of the first year on January 1.

3. Storable inflows in excess of release requirements and

evaporation losses will be credited to each account up to

its maximum allowable content.

4. Although the State does not have an account in the flood
