The central part of the State of Washington has an arid climate and contains a number of saline lakes. Several are meromictic and show a variety of vertical gradients of salinity and temperature. The mixolimnion of Soap Lake has been diluted by increased entry of freshwater from 39.4 g/liter in 1946 to 18.0 in 1964 while the monimolimnion has been maintained at more than 130 g/liter. The stability of the chemocline was studied by an injection of radioactive rubidium. The radioactivity spread laterally in all directions, mostly in a layer less than 2 m thick, to a maximum observed mean radius of 53 m in 13 days. The corresponding eddy diffusion coefficient is 3.2 cm 2 /sec.
