Mr. Yates is an accomplished Senior Hydrologist and water resources expert. His extensive experience — initially with the USGS and also as a consulting hydrologist — has been science-based and focused on projects that require critical thinking skills and the application of hydrologic principles and methods. Mr. Yates is skilled at identifying the critical aspects of complex natural hydrologic and water supply systems most relevant to the client's issues. He develops efficient investigative approaches that combine field studies, computer models, statistics, and traditional analysis methods. He is recognized for his breadth of knowledge in multiple disciplines — including soils, geology, geomorphology, climatology, land use, water use, agronomy, vegetation ecology and fisheries biology — and for his comprehension of the critical aspects of complex natural hydrologic and water supply systems.

Mr. Yates is an experienced project manager with exceptional communication skills, who has consulted successfully with public agencies, private-sector clients, and non-profit groups in groundwater and surface water hydrology, biohydrology, and water resources management. He is an acknowledged expert in basin yield analysis, groundwater modeling, quantification of groundwater budgets, and evaluation of groundwater flow and quality. His projects commonly deal with topics such as detailed historical and future water balances, sustainable yield, long-term water-quality issues related to wastewater and salt/nutrient loading, and impacts of groundwater pumping on aquatic and riparian ecosystems.
