"Natural Clean-Up Crew Boosts Lake Tahoe's Water Clarity to 40-Year High"
Lake Tahoe has achieved a clarity that scientists haven’t seen in 40 years due to an increase in the concentration of zooplankton, which consume particles that inhibit the lake’s visibility, and a depletion in the numbers of Mysis shrimp that normally eat those zooplankton. However, the assistance provided by nature’s clean-up crew may be short-term as Mysis shrimp populations are expected to rebound. Future management options should look at controlling the shrimp population.
