Dr. Zan Rubin worked with Balance from 2005-2008 and again since 2015. He has designed and implemented investigations of complex hydrogeologic, geomorphic, bed-sedimentation, water-quality, and sediment-quality questions in streams, lakes, and wetlands in the working landscapes of the California and throughout the world. Zan has conducted many of the firm’s water quality studies, including multi-year TMDL sediment-transport and bed-condition investigations on San Francisquito Creek and other channels near Stanford University, and throughout Santa Cruz, San Mateo, and Santa Clara Counties. He has also led countywide investigations of water quality in San Mateo and Santa Clara Counties. For the Callippe Preserve Golf Course he designed and implemented a water quality and ‘nuisance flow’ management strategy. On the lower Colorado River, Zan investigated restoration potential in areas of limited water quality, habitat quality, and riparian areas with elevated soil salinity. Internationally, he has been part of a team supporting the national governments of Cambodia, Laos, and Vietnam to model sediment trapping from future hydropower development, to identify projects with the greatest impacts, and to propose dams with alternative sites, designs, and management strategies to minimize sediment trapping, barriers to fish migration, flood risk, and displacement of people.

Working together with a team of smart and curious people to answer questions and find solutions to complex questions in river management.
In the coastal ranges of California. I love the surprises when working in a landscape with such extreme variability in space- microclimates, lithology, vegetation, and variability in time- 2106-2017 has been remarkable, going from record drought to record rain.
I love the Colorado River. I’ve had the opportunity to do months of fieldwork in the headwaters, the Grand Canyon, and down to the Mexican border. It’s a fascinating river and a profound symbol of water in the western US.
