John Carron, PhD

Founder and Principal

John has over 20 years of experience in water resources engineering and consulting, include modeling and management of river basins, reservoirs, and water supply systems; reliability and risk analysis; climate change studies; and water rights engineering. His recent work includes development and analysis of a drought Contingency Plan for the Upper Colorado River Commission member states, technical support for the state of New Mexico in litigation over the Rio Grande compact, feasibility and operational studies for new storage facilities in the Lower Colorado River Basin (Texas), planning studies for the nine Nile River Basin nations, and development of operational decision support tools for the Bureau of Reclamation in the lower Colorado River.  He is an expert in the management of the Colorado River and the “Law of the River”, and has extensive expertise in the development of RiverWare models and their applications to complex water management problems.

Steve Setzer, MS, PE

Water Resources Engineer

Steve has 16 years of experience in RiverWare modeling, water resources planning and management, and surface water hydrology.  Steve served as the primary RiverWare training course instructor while employed at Center for Advanced Decision Support for Water and Environmental Systems (CADSWES) at University of Colorado, Boulder, and continues to conduct training courses for CADSWES on an as-needed basis. Steve is currently developing a suite of daily operations models for the Lower Colorado River Authority (LCRA) in Austin, TX, a long term planning model for LCRA, and a daily operations model of the Colorado River below Parker Dam for the Yuma Area Office of the Bureau of Reclamation.
