<br />the Colorado Division of Wildlife. If warmwater fish species are found <br />in reclaimed ponds from illegal transfers, the ponds will be reclaimed <br />again when it can be scheduled into the pond reclamation program. <br /> <br />Earlier in this document, it was stated that 20% of the floodplain ponds <br />connect with the adjacent river annua77y and that 40% of the ponds <br />connect in one out of 10 years (Mitche77 1995). This topic was <br />discussed at length by Recovery Program participants who concluded that <br />such ponds would have to be reclaimed again after such connections. It <br />was recognized that control of nonnative fish species in ponds that <br />connect annua77y would be an ongoing effort. . Such ponds would be <br />candidates for re-connection with the river to form manmade "embayments" <br />that were discussed earlier in this document. <br /> <br />5. One response indicated that access to remove nonnative fish species from <br />floodplain ponds through mechanical or chemical control methods may be <br />denied by the landowner. <br /> <br />All access to private or public ponds will be made only through Willing <br />landowners. It is recognized that access to a77 floodplain ponds would <br />not be likely. Therefore, the Recovery Program plan was to remove <br />nonnative fishes by mechanical or chemical control methods from less <br />than half the number of ponds along the Upper Colorado and Gunnison <br />rivers. The use of mechanical or chemical control methods is described <br />in Alternative 2 in Section IV ANALYSIS OF ENVIRONMENTAL CONSEQUENCES <br />AND PREFERRED ALTERNATIVE. Several other Recovery Program efforts wil 1 <br />help to control chronic escapement of nonnative fish species. <br /> <br />One of the other methods includes installing mechanical fish control <br />devi ces in ponds with di rect out lets to the rivers. This contro 1 method <br />is described in Alternative 3 in Section IV ANALYSIS OF ENVIRONMENTAL <br />CONSEQUENCES AND PREFERRED ALTERNATIVE. <br /> <br />Another Recovery Program effort is to reconnect the floodplain with the <br />river to a770w the river to function as a natural ecosystem under the <br />habitat restoration initiative. If the ponds can drain into the rivers, <br />it is bel ieved that the endangered fi shes wi 77 benefit through increased <br />production and, at the same time, nonnative fishes will not be able to <br />flourish because the ponds would drain annually preventing population <br />growth of the nonnative species. This action is described in <br />Alternative 4 in Section IV ANALYSIS OF ENVIRONMENTAL CONSEQUENCES AND <br />PREFERRED ALTERNATIVE. <br /> <br />The combination of Alternatives 2, 3, and 4 will manage some of chronic <br />escapement of nonnative fishes from floodplain ponds along the Upper <br />Colorado and Gunnison rivers. It is believed that reducing the numbers <br />of nonnative fishes will reduce predation and competition by nonnative <br />fishes on the endangered fishes with the net result that survival of <br />endangered fishes will increase. <br /> <br />6. Selenium levels in the Upper Colorado and Gunnison rivers may hamper <br />recovery of the endangered Colorado River fishes. <br /> <br />31 <br />
