<br /> <br />Appendix B (Table B .2). The flowing streams <br />characteristically pick up salts as they move <br />across the valley floor to the Price River. <br />Many of the streams which drain wildlands <br />contribute very little flow during the summer <br />months. <br /> <br />The survey indicated that the sslt load <br />in the observed streams was large, with a <br />mean TDS observation of 3650 mg/l and <br />an observed high of 9BOO mg/l. Under such <br />high salt loadings, the springs may have <br />reached saturation with regards to several <br />significsnt minerals. <br /> <br />N <br />o <br />OJ <br />1-'" <br /> <br />Cosl Creek Instrumentation <br /> <br />Coal Creek (Figure 3.1) was chosen for <br />instrumentation for detailed study. The Coal <br />Creek catchment originates in the Book <br />Cliffs, and the streain flows in a southerly <br /> <br /> <br />BOOK CLIFFS <br /> <br />Upper Control Site <br />(RC,RT,RQ,P) <br /> <br /> <br /> <br />R ad <br /> <br />Coal Creek <br />Macrochannel <br /> <br /> <br />Spring <br />Middle Site <br />(RT,RRH,W,NR, RPl <br /> <br />West <br />Raingage <br />o <br />(P) <br /> <br />East Raingage (Pl <br />/ <br />/ <br /> <br />Lower Control Site <br />( RC,RT,RQ,P) <br /> <br />Figure 3,1, Coal Creek instrumentation, <br /> <br />1 <br /> <br />..; <br />-~1 <br />! <br /> <br />direction to its confluence with the Price <br />River near the town of Wellington. An <br />upper control site (Figure 3.1) was located <br />at the point at which the stream emerges from <br />the Book Cliffs. The flow at thia location <br />is essentially perennial, with a baseflow <br />of about 1 cfs during the snowmelt period <br />declining to 0.1 cfs in the late summer. The <br />average stream aalinity at this point is <br />about 500 mg/l. Diasolved salts are rapidly <br />picked up with a TDS of 3420 mg/l measured at <br />Highways 6 and 50 (Appendix B). <br /> <br />An 8.2 mile study section Was chosen <br />extending downstream from the base of the <br />Book Cliffs. Access to the Coal Creek <br />channel was gained from a paved road which ia <br />located adjacent to the channel on the west <br />side, and which traverses the entire length <br />of the study section. The catchment, except <br />for a amall irrigated farm, consists of <br />natural lands. <br /> <br /> <br />~m <br /> <br /> ~ <br /> N <br /> I <br />I , , I <br />0 I 2 3 <br /> Scale (miles) <br /> <br /> <br />RQ- Recording Flow <br />NR- Net Radiation <br />RT - Recording Temperature <br />RC- Recording Conductivity <br />P - Cumulative Precipitation <br />W - Cumulative Wind Speed <br />RRH- Recording Relotive Humidity <br />RP -Recording Precipitation <br /> <br />18 <br />
