<br />. <br /> <br />e <br /> <br />e <br /> <br />Rationale: The Recovery Program recently installed a fish passage at Redlands to open up 50 <br />miles of the Gunnison River as squawfish and razorback sucker habitat. Passages on the <br />Colorado River to provide habitat to Rifle are being planned. Presently, there are about 800 miles <br />of habitat for Colorado squawfish and razorback sucker in the upper basin. Expansions via fish <br />passages will bring this close to 900-950 miles. There is no scientific or legal basis for asserting <br />that if flow recommendations cannot be achieved in the IS-mile reach, that recovery cannot be <br />achieved. The IS-mile reach is less than 2% of the available habitat, yet it has been and is <br />absorbing an enormous amount of Recovery Program resources. <br /> <br />The Colorado Squawfish Recovery Plan (USFWS, 1991) does not require "recovery" in the 15- <br />mile reach. Down listing should occur when naturally self-sustaining populations are maintained <br />from "the Colorado River from Palisade, Colorado to Lake PoweIl," together with the Green <br />River subbasin. The Colorado River populations of squawfish extends from Lake Powell to <br />Palisade, and are not the IS-mile reach population of Colorado squawfish. <br /> <br />C. A realistic role in recovery should be assigned to the IS-mile reach that recognizes <br />existing and future depletions, and realistic recovery actions for the IS-mile reach. <br /> <br />Rationale: The IS-mile reach presents a significant conflict between the USFWS flow recommen- <br />dations and reality. Flow recommendations for the IS-mile reach (Osmundson, 1995) recom- <br />mends 400,000 acre-feet/year more water than is presently available. In recent filings on the 15- <br />mile reach, the Colorado Water Conservation Board set aside a 100,000 acre-feet carve out for <br />new depletions, with as much as 300,000 acre-feet of modifiable flow to accommodate compact <br />development, based on the potential for compact development depletions on the main stem of the <br />Colorado River. <br /> <br />At the suggestion of the USFWS Regional Director, a discussion is ongoing regarding how to <br />deal with the great discrepancies between the flow recommendations and present and future <br />reality, and how the Recovery Program will be maintained as the reasonable and prudent <br />alternative for existing and future depletions upstream of the IS-mile reach on the Colorado <br />River. These depletions are inevitable as Colorado develops its compact entitlement. As agreed, <br />existing depletions are to be fully mitigated by the Recovery Program (USFWS, 1987). <br /> <br />USFWS has suggested that recovery must take place in the IS-mile reach of the Colorado River. <br />This is unjustified. This position is a lose-lose position for the Fish and Wildlife Service and the <br />Recovery Program. It is abundantly clear that 1) the flow recommendations cannot be met now, <br />and 2) future depletions will further reduce flows in the IS-mile reach. A realistic role for the 15- <br />mile reach needs to be identified, relative to overall recovery of the species, and based on feasible <br />recovery measures for the IS-mile reach, including habitat development and nonnative control. <br />The role of the IS-mile reach should be determined in cooperation with all RIP participants. <br /> <br />7 <br />
