A central station in Lake Tahoe has been sampled from the surface to 400 m at four times of year for measurement of phytoplankton biomass; particulate and dissolved organic carbon, nitrogen, and phosphorus; inorganic nutrients; primary productivity; and light, temperature, and oxygen. The gradients observed in distribution of dissolved and particulate material from the surface to 400 m did not vary greatly from summer to winter, even though the water temperature at the February sampling time was almost isothermal. When the water in Tahoe undergoes a winter overturn, biological activity in the lake soon returns the water column to the distinct vertical profiles of inorganic and organic material reported here.
