Presentation peers into Tahoe’s clarity

Staff Reports

Dr. Alan Heyvaert of the Desert Research Institute will present research findings and recommendations that address Lake Tahoe’s aquatic nearshore environment at a public lecture at 6 p.m. April 3, hosted by the U.C. Davis Tahoe Environmental Research Center. A no-host bar at 5:30 p.m. precedes the presentation.

Suggested donation is $5. The Tahoe Center for Environmental Sciences is located 291 Country Club Drive, Incline Village (on the campus of Sierra Nevada College).

Lake Tahoe’s nearshore is an important zone of relatively shallow water where the lake meets the land. The nearshore environment is inherently complex and vulnerable to aquatic invasive species, warming from climate change, recreation, development, and changes in lake levels. Conditions differ widely around the lake’s nearshore, in contrast to the more uniform open waters.

The “Lake Tahoe Nearshore Evaluation and Monitoring Framework” report examines the unique aspects of this important zone. The report evaluates existing California, Nevada and TRPA standards and thresholds related to this region; presents a new conceptual model for evaluating nearshore environmental health; and proposes a monitoring strategy intended to help resource managers identify the most meaningful physical, chemical and biological indicators of healthy nearshore conditions.

Heyvaert is a limnologist and acting senior director of the Center for Watersheds and Environmental Sustainability at the Desert Research Institute. His fields of interest include biogeochemistry, paleolimnology and watershed management. He has worked for many years on water quality issues in the Lake Tahoe Basin.
