• is located neaz the Fish Creek Tipple; and site 1003 is located downstream of the Fish Creek Tipple. During <br />1998, the Fish Creek surface water monitoring sites generally required monthly flow and field parameter <br />measurements with quarterly water quality sample collection. The monitoring requirements for all sites except <br />302 are further described to require 12 flow and Feld parameter monitoring instances to occur between March and <br />September along with 4 water quality sampling events. All monitoring requirements were fulfilled a[ these sites <br />in 1998. Required monitoring at site 302 included monthly flow, field parameter, and water quality sampling <br />during the irrigation season June through September. Site visitation requirements were met at site 302. <br />Tables 39 through 43 provide summaries of the 1998 Water Year data collected at Fish Creek surface Flow sites. <br />Tables 39a through 43a provide period of record statistical summaries of collected data at each site. Figures 72 <br />through 91 provide graphical representations of water levels and selected water quality parameters recorded a[ <br />each site. Again, typical flow pattems were exhibited at these sites with spring mnoff periods accounting for the <br />peak flows observed. Runoff magnitudes were above average during 1998 based upon comparison with previous <br />years data and peak flow estimates were in some instances derived from the exveme high end of the rating curves <br />developed for each site. These values represent best estimates but are unsubstantiated with measured data. At all <br />sites, the inverse relationship between flow and field conductivity was evident. <br />Then water quality parameter values noted to occur outside of previously established ranges for these sites, during <br />199 included: new maximum laboratory pH value, and new minimum dissolved solid value for site 1002 (Table <br />• 41); a new maximum lab pH value for site 27A(Table 42); and a new maximum value for selenium (TR) for Site <br />1003 (Table 43). <br />Trout Creek: Three surface flow monitoring sites on Trout Creek are utilized. Site 301 is located on Trout Creek <br />above the confluence with Middle Creek; site 69 is located on Trout Creek below [he confluence; and site 1005, <br />established in 1994, is located downstream of confluence of Fish Creek and Trout Creek. Required monitoring <br />for these sites included monthly Flow, field parameter, and water quality sampling during [he irrigation season <br />June through September. Site visitation and water quality sampling requirements were met at these sites during <br />1998. <br />Tables 46 through 48 provide summaries of the 1998 Water Year data collected at Trout Creek surface flow sites. <br />Tables 46a and 48a provide period of record statistical summaries of collected data at sites 301, 69, and 1005. <br />Figures 92 through 101 provide graphical representations of water levels and selected water quality parameters <br />recorded at each site. For the most part, typical pattems were observed. Again, peak flow estimates were derived <br />from extrapolated flow curves in some instances. <br />Identified water quality variances include new maximum values far lab pH and zinc (TR) recorded at site 69 <br />(Table 47). Several changes in historical range figures are also noted at site 1005 (Table 48). These include new <br />. maximum values for dissolved solids, ammonia. The database for this site is somewhat limited, with just over <br />-9- <br />
