Geoffrey Schladow is Professor of Civil and Environmental Engineering and Director of the Tahoe Environmental Research Center. He serves on numerous federal, state and local government committees, providing technical advice on lake, stream and estuary systems throughout California. His principal area of research interest is the interaction between fluid transport and mixing processes with water quality in natural and engineered systems. Using a combination of field experimentation and numerical modeling, he is better quantifying the critical flux paths in these systems. His recent research has included the development of the Lake Tahoe Clarity Model, the modeling of eutrophication in the Salton Sea, the use of remote sensing for measuring water currents and water quality, and the measurement and modeling of flows in the Napa-Sonoma marsh complex. His work with the Watershed Center has included the modeling of North Delta restoration and flood flows, and the measurement and modeling of the hydrodynamics and oxygen stratification in the Stockton Deep Water Ship Channel.

Vertical redistribution of zooplankton in an oligotrophic lake associated with reduction in ultraviolet radiation by wil...
Published in Geophysical Research Letters
We used a natural experiment to test whether wildfire smoke induced changes in the vertical distribution of zooplankton in Lake Tahoe by decreasing incident ultraviolet radiation (UV). Fires have a variety of effects on aquatic ecosystems, but these impacts are poorly understood and have rarely been observed directly. UV is an important driver of z...
Seasonal nearshore sediment resuspension and water clarity at Lake Tahoe
Published in Lake and Reservoir Management
Reardon KE, Moreno-Casas PA, Bombardelli FA, Schladow SG. 2016 Seasonal nearshore sediment resuspension and water clarity at Lake Tahoe. Lake Reserv Manage. 32:132--145. Motivated by management challenges due to declining water clarity at Lake Tahoe, California–Nevada, we synthesized field observations and modeling of wind-driven nearshore sedim...
Rapid and highly variable warming of lake surface waters around the globe
...Published in Geophysical Research Letters
In this first worldwide synthesis of in situ and satellite‐derived lake data, we find that lake summer surface water temperatures rose rapidly (global mean = 0.34°C decade−1) between 1985 and 2009. Our analyses show that surface water warming rates are dependent on combinations of climate and local characteristics, rather than just lake location, l...
