This alternative would allow the routine stocking of largemouth bass. <br />bluegill, black crappie, channel catfish, mosquitofish, and fathead minnows in <br />all isolated waters located 5 feet above the Ordinary High Water Line (OHwL;. <br />without FEMA approved dikes and in all isolated waters located above an <br />elevation of 6.500-feet msl (Figure 1). <br />Monitoring of changes in the nonnative fish populations in habitat occupied by <br />the endangered fish for fish that are stocked on a routine basis will be done <br />through the Recovery Programs Instream Standardized Monitoring Program (ISMP) <br />and/or other studies being conducted by the Recovery Programs or State <br />wildlife agencies. <br />Instances when and where nonnative fishes can be stocked on a routine basis <br />(not requiring a case-by-case review) are presented in Table 4. Stocking of <br />nonnative fishes that are not managed in the Upper Basin at the present time <br />or are not included under routine stocking would require evaluation on a <br />case-by-case basis to ensure that the proposed stocking of these fishes will <br />not adversely affect the endangered fishes. <br />G. ALTERNATIVE 5 <br />This alternative is similar to alternative 4 in that it provides more cases <br />where routine stocking can occur than alternatives 2 and 3. The primary <br />difference between this alternative and alternative 4 is that, alternative 4 <br />states that a pond can be bermed to FEMA specification to functionally remove <br />it from the portion of the floodplain in question. This alternative has no <br />berming requirements or opportunities but states that limitations placed on <br />stocking within a specific floodplain have no exceptions. Situations that <br />require a case-by-case review for this alternative are identical to <br />alternative 1. <br />Monitoring of changes in the nonnative fish populations in habitat occupied by <br />the endangered fish for fish that are stocked on a routine basis will be done <br />through the Recovery Programs Instream Standardized Monitoring Program (ISMP) <br />and other studies being conducted by the Recovery Programs or State wildlife <br />agencies. This requirement is identical to alternative 1. <br />Instances when and where nonnative fishes can be stocked on a routine basis <br />(not requiring a case-by-case review) are presented in Table 5. Stocking of <br />nonnative fishes that are not managed in the Upper Basin at the present time <br />or are not included under routine stocking would require evaluation on a case- <br />by-case basis to ensure that the proposed stocking of these fishes will not <br />adversely affect the endangered fishes. <br />14
