Relation Central Utah Project; Western Waters Digital Library; water quality in the diked biked areas would become very salty in a f few ew years these areas are essentially shallow evaporation ponds that rapidly become brine ponds and within a few years have TDS values exceeding 50000 mgl mg1 mgt during very wet years these brine ponds would be diluted severalfold several fold by precipitation and spillage only to return to their earlier brine condition during drier periods the only way to avoid this condition in the long term ponded bonded water behind b the dikes is to periodically pump out the brine thus removing much of the accumulated salts in this case the question of where the ponded bonded water would be pumped to would have to be addressed results sensitivity the sensitivity of salt concentration projections to system variables is important to interpretation of these projections As noted earlier natural wet and dry cycles are the dominant factors in salt concentrations variations manyfold many fold changes result over a several year period as the two or three year precipitation varies well above or below long term averages mineral groundwater inflow estimates are an important factor in lake salt balances and indirectly on the water balances salt concentrations and inflow volumes for these waters are difficult to establish accurately since they occur mainly as scattered springs and seeps many of which are beneath the lake and essentially unmeasurable these flows make up only about 3 of the inflowing flowing inblowing in water volume but are large sources of TDS 202 20.2 202 sodium 365 36.5 365 potassium 303 30.3 303 chloride 451 45.1 451 and sulfate 169 16.9 169 see table 2a aa 11 measurable mineralized springs and seeps along the lakes shoreline eg at lincoln point bird island pelican point and saratoga vary markedly in salt concentrations although they are generally 1300 to 7000 mg1 mgl ugi mgt TDS and approximately an order of magnitude higher than other surface and fresh groundwater inflows these flows can dramatically change the water balance since they are the source for the salt percentages mentioned above suppose the mineralized inflows were predominantly at the lower end of the TDS range say 2000 mgt mg1 mgl TDS rather 3 16
