beak <br />general notes taken on physical characteristics; such channels include small <br />intermittent streams which drain into the North Fork Gunnison River from the <br />proposed permit area. <br />Field measurements were taken at the primary study sites in the permit <br />area as well as Anthracite Creek and Muddy Creek (downstream of Paonia <br />Reservoir) for temperature, pH, conductivity and dissolved oxygen. These <br />parameters are important because they are often indicative of the in- <br />stantaneous state of water quality. Measurements were obtained during the <br />first day of sampling using portable field units calibrated to APHA (1976) <br />standards. Temperature (degrees Centigrade - oC) and dissolved oxygen (ppm) <br />were measured using a YSI Model 60, pH was measured with a Corning Model <br />610 A, and conductivity (~,miios/cm) was measured using a Chemtrix Type 70. <br />Water samples were also collected at stations A-F for additional laboratory <br />analysis. <br />3.2 Results and Discussion <br />Key physical characteristics of selected survey sites on Anthracite <br />Creek, Muddy Creek (downstream of Paonia Reservoir), and the North Fork <br />Gunnison River at the Hawk's Nest Permit Area are presented in Table 3.0-1. <br />Channel stability and habitat evaluations were performed only on the North <br />Fork in conjunction with aquatic biological sampling at permit area stations <br />and are also summarized in Table 3.0-1. <br />Field measurements generally indicated near normal water temperature <br />and conductivity for the month (USGS 1974), as well as saturated dissolved <br />oxygen at all stations.
