<br />1338 <br /> <br />specimens will be preserved in 10% formalin and returned to the New ,Mexico Department of <br />Game and Fish Laboratory for identification, enumeration, and measurement (total length and <br />weight). Field collection number, habitat number, and river mile will be recorded on a water- <br />proof label and placed in each specimen container. Location of site (latitude and longitude) will <br />be determined with a GPS unit. Identification of all retained rare fishes will be confirmed by <br />personnel of the Museum of Southwestern Biology. Preserved specimens will be accessioned <br />to the New Mexico Department of Game and Fish Collection of Fishes or the Museum of <br />Southwestern Biology. <br /> <br />Within each third-mile, shoreline habitats of the primary channel will be sampled. At each <br />designated mile, all mesohabitats (e.g., riffle, debris pool, and shoal) along 200 m (near center <br />of mile) of shoreline will be sampled. All mesohabitats present will be sampled in approximate <br />proportion to their availability within the site. Regardless of the number of mesohabitats present <br />, at a primary channel site, at least 5 seine hauls will be made with a drag seine (3.2 x 1.6 m, 4 <br />mm mesh). The shoreline (river right or left) sampled will be dependent upon accessibility of <br />the shoreline. Where more than one shoreline is accessible (and can be seined efficiently), that <br />with greater habitat diversity/complexity will be sampled. Location (latitude and longitude) will <br />be determined with a GPS unit. Specimen and habitat data will be obtained and recorded as <br />required for secondary channel sampling. All retained specimens from primary channel <br />sampling will be preserved separately from the adjacent secondary channel collection. All <br />retained specimens will be accessioned to the New Mexico Department of Game and Fish <br />Collection of Fishes or the Museum of Southwestern Biology. <br /> <br />c- <br /> <br />Backwaters and embayments (>25 m2) not located within structured primary channel sampling <br />sites also will be sampled. During periods of low flow, secondary channel mouths frequently <br />function as backwaters or embayments. In this monitoring effort, secondary channt'il mouths <br />without surface inflow from upstream will be treated as backwater/embayment habitat. The <br />maximum number of backwaters or embayments sampled will be one per mile. Three seine <br />hauls will be made in each backwater or embayment sampled. All specimens collected, except <br />rare fishes, will be retained and returned to the laboratory for identification and enumeration. <br />All rare fish will, be' measured and released; those > 150 mm will be PIT tagged. Data" <br />collection and recording of relevant information (including GPS determined location) will be the <br />same as for secondary and primary channels. <br /> <br />,~ .' <br /> <br />Water quality data (ambient temperature, water temperature, dissolved oxygen, conductivity, and <br />salinity) will be measured in each sampled secondary channel, at primary channel sites and in <br />backwaters/embayments. Secondary channel water quality data will be obtained a sufficient <br />distance from the inflow to the secondary channel to minimize primary channel influences. All <br />water quality data for each sample will be recorded on standard field forms. <br /> <br />Products: <br /> <br />Data for the October 1999 monitoring effort will be summarized by geomorphic reaches. <br />Minimally, the annual report will report density per species (number/m2) per geomorphic reach, <br /> <br />L <br /> <br />Work Plan FY99.wpd <br /> <br />20 <br /> <br />Budget and Work Plan FY99 <br /> <br />" <br />"', <br /> <br />( <br /> <br />I <br />
