<br />Red Wash Launch area (RMI - 298.57298.0), Sportsman's Drain (RMI 296.5), <br />Greasewood Corral (RMI 251.9), and Old Charlie Inlet (RMI 251.8). In the lower <br />Green River, sampling efforts will be concentrated at near town of Green River (RMI <br />120.0), mouth of San Rafael River (RMI 97.0), Potato Bottom (RMI 38.0737.0), <br />Millard Canyon (RMI 33.5), Anderson Bottom/Bonita Bend (RMI 31.5731.0), and <br />Holeman Canyon (RMI 27.8). Sampling will be conducted at each site twice weekly <br />during at least early/mid May7mid June. The sampling period will be adjusted based on <br />timing and duration of spring flows, onset of mainchannel water temperatures $ 140C, <br />and temporal occurrence of larvae. Each habitat at each sampling time will be sampled <br />with at least three light traps and possibly three seine hauls (number of collections will <br />depend on size and <br />complexity of habitats). It is often effective to set light traps in or near emergent <br />vegetation. Larger fish identifiable in the field will counted and measured on site and <br />released alive. Other fish will be euthanized with an overdose of tricaine <br />methanesulfonate (MS-222), preserved in 100% ethanol, and returned to the laboratory <br />for processing. Units of effort will be hours each light trap is set during darkness and <br />area sampled by each seine haul. Water temperatures at monitoring sites will be <br />recorded using StowAwayTM Enhanced Temperature Loggers. <br /> <br />Page 6 of _ <br />
