Unless information can be presented which documents oxygen demands resulting from something other than TSS, then TSS loading should be reduced. Furthermore, TPWD has observed heavy accumulations of solids in eddy currents immediately downstream of FM 842 on 6 July 1994. It is likely that unless depositional areas, such as eddy currents, are investigated, TSS will not appear to be a problem Paper Mill Creek. Current velocities will be high enough to carry solids into the Angelina River and continue down river until velocities allow. It is likely that solids are not settling out until they reach the riverine segment of Sam Rayburn Reservoir.
Hydraulic velocity slows progressively downstream.
Km downstream PM Cr. Km downstream PM Cr. Km downstream PM Cr. Dissolved oxygen concentrations are also lower downstream in this area. The Study documented elevated chloride levels in the Angelina River downstream of Paper Mill Creek.
