| Relation | Central Utah Project; Western Waters Digital Library; BOD and TDS violations are by far the most prevalent violations in utah lake however these are largely natural and uncontrollable since the high TDS is mainly the result of evaporation from the lake and high BOD the result of biological growth and decay in the lake itself there are fewer other violations in the lake compared to its tributaries tributa ries since pollutant degradation dilution and mineral precipitation are at work in the lake more violations occur along the eastern margin of the lake where most of the surface tributaries tributa ries enter and in the southern margins of goshen bay where surface wash shallow water and evaporation are dominant factors BOD values are high in provo bay often exceeding 10 mg1 mgl mgt as a result of large organic loads from some tributaries tributa ries as well as the high biological productivity in the shallow bay itself temporal changes in salts total dissolved solids TDS in utah lake and its tributaries tributa ries vary markedly over time wet and dry cycles that last several years cause larger variations than do seasonal factors figure aa 2a 1 displays the TDS results from a 50 year simulation of conservative salts average monthly TDS ranges from a low of 420 mgl mg1 ugi mgt in may 1952 to a high of 14500 mgl mg1 mgt in september 1935 the lowest annual TDS average was 570 mgl mg1 ugi mgt for water year 1953 and the highest was 4610 mgl mg1 ugi mgt in 1935 these TDS variations are largely the result of natural longer term wet and dry cycles which cause large variations in the amount of inflowing flowing inblowing in water larger volumes of inflowing flowing inblowing in water dilute the saltier lake water and also flush saltier water from the lake via the jordan river table 2a aa 11 lists sources of inflowing flowing inblowing in salts as computed in simulations studies A few observations concerning these sources are 1 mountain streams and rivers carry largely bicarbonates carbonates bi of calcium and magnesium while they contribute 38.9 389 percent of the total water inflow they carry only 22.5 225 225 percent of the TDS and less than 13 percent of sodium potassium and chloride 221 2 21 |
