<br />variable nutrient loadings due to snowmelt runoff and thunderstorm <br /> <br /> <br />events can be expected; hence, more frequent sampling surveys are <br /> <br /> <br />suggested. The variables to be analyzed for each site survey are <br /> <br /> <br />summarized in Table 2. In general, field measurements will be made at <br /> <br /> <br />each site visit for temperature, dissolved-oxygen concentration, pH, and <br /> <br /> <br />specific conductance. Through recording the time of the site visit and <br /> <br /> <br />the stream level from the USGS staff gate, the stream discharge can be <br /> <br /> <br />calculated from the currently applicable rating curve for each <br /> <br /> <br />stream-flow site, It is assumed that staff-gate readings and access to <br /> <br /> <br />applicable rating curves can be obtained from the USGS. Samples will be <br /> <br /> <br />collected at each site for each survey for analyses of nitrogen and <br /> <br /> <br />phosphorus nutrient species, alkalinity, and total suspended solids <br /> <br /> <br />(Table 2). With this schedule anticipated at each site, a total of 32 <br /> <br /> <br />samples will be collected over the monitoring year. To the extent <br /> <br /> <br />possible, stream-inflow site surveys would be conducted on the same day <br /> <br /> <br />as the in-reservoir monitoring. <br /> <br /> <br />Task 2 In-Reservoir Monitoring <br /> <br /> <br />-- To assess seasonal variability and possible long-term trends in <br /> <br /> <br />nutrient, chemical, and biological conditions in Bear Creek Reservoir, <br /> <br /> <br />three in-reservoir locations. would be sampled for selected chemical <br /> <br /> <br />constituents and biological-indicator variables. These sampling sites <br /> <br /> <br />generally would be located as follows: one site each at the <br /> <br /> <br />tributary-inflow inundated areas where Bear Creek and Turkey Creek enter <br /> <br /> <br />the reservoir from the northwest and southwest, respectively; and a third <br /> <br /> <br />site in the deeper part of the reservoir near the impoundment dam to the <br /> <br /> <br />east (Figure 1). Samples collected at each of the three reservoir sites <br /> <br />37 <br />
