Solute concentrations in atmospheric deposition and stream water were measured in two mixed-conifer catchments (Tharp*s and Log creeks) in the Sierra Nevada of California from 1984 through 1995, a period including a 6-year drought and a prescribed burn in one catchment. The effects of prescribed burning in the Tharp*s Creek catchment significantly increased the concentrations of most solutes in stream water. In the first year after prescribed burning, the VWM (volume-weighted mean) concentrations of acid anions in stream water increased proportionally more than those of the base cations, and ANC (acid neutralizing capacity) more than doubled. Sulfate and NO3- increased proportionally mere in stream water than any other ions after the fire, but pre- and post-burn VWM pH were not significantly different. VWM
