Caption:  The source table "gwlabdat.dbf" contains data on total dissolved solids collected by the North Coast Regional Water Quality Control Board staff and reflects samples from 1988 to 1992 (see Chart Table*). To see an index of sample locations by river mile (rm), you may tab to the bottom of this text field. Shasta River total dissolved solids increase substantially in a downstream direction with highest levels often found below the Montague-Grenada Road (river mile 10.54). TDS can stem from many sources. Elevated levels in the lower Shasta Valley may result from mineralized spring flow and nutrient and mineral enrichment resulting from agricultural runoff. Locations by river mile of sampling stations are Highway 263 = rm 7.25, Anderson Grade Rd. = rm 8, Yreka-Ager Rd. = 10.54, Highway 3 = rm 12.79, Montague/Grenada Rd = 15.17, A-12 = rm 20.99, East Louie Rd. = 31.86, Riverside Dr. = 37.73. A list of parameters is as follows: AS = arsenic, B= boron, CA= calcium, CL = chloride, FE= Iron, MG= manganese, K= potassium, SI= silicon, NA= sodium, S= sulfur, NH3N = total ammonia nitrogen, NO3N = total nitrate, PO4P= total phosphate phosphorus, TKN = total Kjeldahl nitrogen, ALK= alkalinity, Hardness= hardness, PHLAB = laboratory pH, DO = dissolved oxygen, CONDLAB = laboratory conductivity, TDS = total dissolved solids, BICARB= bicarbonate, CO2FREE= free CO2, CO2TOTAL= total CO2, CARBONATE= carbonate, and TURBIDITY= turbidity
