<br />UJ24~6 <br /> <br />(1) Only salmonids can be stocked by the State or private landowners within the 10-year <br />floodplain of habitat designated as critical to the endangered fishes. <br /> <br />(2) Chronic escapement of nonnative, warmwater fish species will be reduced in the <br />critical habitat of the endangered fishes by reducing or eliminating the numbers of <br />existing nonnative, warmwater fishes using chemical control in the 10-year <br />floodplain. <br /> <br />(3) Stocking of Largemouth bass, bluegill, and black crappie will be allowed in ponds <br />within the 10- to 50-year floodplain. <br /> <br />Such stocking would be preceded by concurrent progress described in Item (2) above, <br />chemical reclamation of target waters, and installing fish screens or other fish <br />control structures to eliminate, to the extent practical, escapement of nonnative <br />fishes from pond~ connected to the river. <br /> <br />(4) The total water surface area reclaimed in the 0- to 10-year floodplain must equal or <br />exceed the total water surface area to be stocked with nonnative, warmwater fish in <br />the 10- to 50-year floodplain. <br /> <br />(5) A fish management outreach program will be explored and implemented with private <br />landowners to ensure that stocking of nonsalmonid, nonnative fishes is compatible <br />with the recovery of the endangered fishes. <br /> <br />o~ to 10-year Floodplain <br /> <br />Reclaim pond or Lake and stock with trout. <br /> <br />10- to 50-year Floodplain <br /> <br />Reclaim pond or lake and stock with trout. <br />Reclaim pond or lake, install fish control device in waters with a connection to <br />upper basin rivers, and replace present fishes with largemouth bass, bluegill, <br />and black crappie. <br /> <br />(6) The Colorado Oivision of Wildlife will implement a program to monitor compliance with <br />and enforce these conditions. <br /> <br />(7) Ponds in the 0- to la-year floodplain will be ieclaimed in the event they become <br />repopulated with nonnative, warmwater fish species through flooding or other means. <br />Reclamation of connected ponds must occur in a timely manner after repopulation by <br />nonnative, warmwater fishes. <br /> <br />3. Reservoirs that are above the 50-year floodplain but have a direct <br />connection to rivers in the Upper Colorado River Basin (e.g., <br />Elkhead Reservoir, Highline Reservoir, and others) will be equipped <br />with a fish control structure or device before the continued <br />stocking of nonnative, warmwater fish species will be allowed. <br /> <br />V. STOCKING OF NONNATIVE FISHES THAT PRESENTLY OCCUR BUT ARE NOT MANAGED <br />IN THE UPPER COLORADO RIVER BASIN+ <br /> <br />Stocking of nonnative fishes that are not managed in the Upper Basin at <br />the present time will require evaluation on a case-by-case basis to <br />ensure that the proposed stocking of these fishes will not adversely <br />affect the endangered fishes. <br /> <br />1. Requests to stock nonnative fish species that are not presently <br />managed by stocking in the Upper Basin (Table 2) in locations or <br />situations not listed in Table I will be evaluated on a case-by- <br />case basis. <br /> <br />5 <br />
