Documentation of the water quality system was added to the RiverWare help: Water Quality Overview in Water Quality.

The Predictor Corrector (given Inflow Salt Concentration) salt calculations on reservoirs now better handle situations where the reservoir runs out of water. When this occurs, the reservoir is treated like a reach and the salt concentration is set to a weighted salt average of the inflows to the reservoir. For more information, see Solve Pred-Corr Salt Given In in Water Quality.

In addition, the Simple Well-Mixed salinity dispatch methods no longer set diversion salt concentration equal to zero if diversion is zero. This was leading to unusual dispatching patterns. Now, if Diversion is zero, the concentration is non-zero but the Diversion Salt Mass will still be zero.
