<br />'000186 <br /> <br />REDUCE NONNATIVE FISH AND SPORTFISH IMPACTS <br /> <br />C-20 Highline O&M: <br /> <br />Monitoring of the net should continue but additional effort should be made to ensure that the <br />algae load not become confluent and limit water exchange during the period of high inflow in the <br />spring and fall. Additional shoreline work will be continued to reduce the sand and gravel <br />encroachment onto the west end ofthe net. <br /> <br />Cleaning operations will be focused to the period prior to high inflows - early March and Late <br />August. Cleaning will be conducted using the Colorado Division of Parks (CDPOR) barge and <br />the highly efficient self-contained pump using lake water. <br /> <br />109 Middle Green Northern Pike: <br /> <br />Continue with northern pike control in the middle Green River. Focus more on areas known to <br />be concentration areas for northern pike including the Jensen and Duchesne River areas. <br />Continue age analysis using cleithra to track changes in the composition of the middle Green <br />River northern pike population. Continue collection of data on other sympatric species <br />encountered while conducting removal efforts. <br /> <br />We also recommend expanding the control efforts to target smallmouth bass. <br /> <br />110 Lower Yampa Catfish: <br /> <br />1. We recommend that removal efforts of channel catfish from the Yampa River in DNM be <br />continued. <br /> <br />2. Because of the increased abundance in Yampa Canyon, we recommend adding the <br />removal of small mouth bass to the SOW. <br /> <br />3. Due to poor results we recommend against removal efforts with fyke nets at Deerlodge <br />and Echo Parks. <br /> <br />4. We recommend that control reaches be eliminated and community response monitoring <br />be reinstated. This is particularly important given the rising abundance of smallmouth <br />bass. <br /> <br />98a Middle Yampa Northern Pike: <br /> <br />1. Establish early communication between and within affected agencies. <br />2. Provide a consistent message for agencies and affected publics. <br />3. Consider more intensive removal sampling in order to obtain a removal effect. <br />4. Focus removal studies in concentration areas that include Little Yampa Canyon and <br /> <br />2003 Report Recommendations, <br />
