-description real or character value that defines the temperature of evaporated water $(e.g., ^{\circ}C or ^{\circ}F)$ for the reach. If this temperature value is larger than the simulated temperature in the reach, then the evaporated water will be removed at the same temperature as the reach.  If the Options block includes a TIMESERIESFILE entry (see the ``Time-Variable Input'' section), values can be obtained from a time series by entering the time-series name in place of a numeric value.
+description use of the EVAPORATION keyword is allowed in the LKE package; however, the specified value is not currently used in LKE calculations.  Instead, the latent heat of evaporation is multiplied by the simulated evaporation rate for determining the thermal energy lost from a stream reach.
