In addition to the minimum bypass requirements at each of these sites,
a minimum flow requirement must be met on the Fryingpan River at
Thomasvi11e river gaging station as specified in the Operating
Principles. This minimum requirement is as follows: April - 100 ft3/s,
May - 150 ft3/s, June - 200 ft3/s, July - 100 ft3/s, August - 75 ft3/s,
and September - 70 ft3/s or the natural flow, whichever is less.

When it appears that these flows wi 11 not be met, the divers ions into
the Project system are decreased or stopped, whichever is necessary to
meet the bypass requirements. The Hunter Creek System, which drains
into the Roaring Fork River, can continue diverting water into
Boustead Tunnel during these times.

Exhibit 4 shows the daily flows at the Thomasville River gaging
station and the average daily minimum flow requirements during the
period of diversions from the Fryingpan River.

C. PrOject Diversions

The water year 1988 outlook used a Project diversion of
3,000 acre-feet for the most probable runoff condition. The March 1,
April 1, and May 1 forecasts, based on Soil Conservation Service snow
course data, projected available diversions of 45,000 acre-feet,
33,500 acre-feet, and 25,300 acre-feet, respectively. Due to restricted
space in the East Slope storage system, only the Twin Lakes Reservoir
