this scenario for minimum stream flow purposes when storage is below

target and when the P&M water right is out of priority, but only to

support a 200 cfs minimum stream flow. This scenario shows the effect of

asserting the P&M priority for instream purposes in the amount of 300 cfs,

assuming all existing conditions and operational criteria remain

unchanged.

Scenario 3: Releases from Blue Mesa storage are made to support a 300 cfs

minimum stream flow below the Gunnison Tunnel, and a 2000 cfs minimum

stream flow at Westwater. No direct flow priority for these purposes is

assumed. But 45,000 acre feet of water is reserved for the purposes of

primary M&I supplies in this scenario, and is released through the Black

Canyon on a constant year round pattern. This scenario examines the

effect of increasing the criterium for making Blue storage releases for

minimum stream flow purposes in the Black Canyon from 200 to 300 cfs, of

adding the Westwater criterium, and of delivering M&I water through the

Canyon.

Scenario 4: The P&M priority for 300 cfs is asserted for minimum stream

flow purposes both in the Black Canyon and at Westwater, along with Blue

Mesa storage releases based on the 300 cfs and 2000 cfs criteria, while

45,000 acre feet of M&I supplies are again delivered through the Canyon on

constant, year round basis. This scenario shows the c~Bbined effect of

exercising the P&M priority and of increasing the criteria for Blue Mesa
storage releases.
