Are fish in hot water?


This talk will review evidence for a multi-decade warming trend in the lower Klamath River, California, and discuss options for assessing similar "hot water" situations around the country using biological models that range from very simple to relatively complex.


Speaker bio:

Mr. Bartholow has been an ecologist for the U.S. Geological Survey in Fort Collins, Colorado since 1983. He has designed, developed, tested, and transferred methods to assess the impacts of water development activities on aquatic ecosystems nationwide. Specific responsibilities have included:

- developing a decision support system for the Klamath River,
- developing a fish population model for evaluating water management decisions,
- training for and enhancement of mechanistic stream temperature models,
- reservoir water quality modeling,
- teaching classes in appropriate analytical techniques, and
- providing expert advice to field personnel.

Recent work also included an economic analysis of alternative contraceptive programs for Bureau of Land Management wild horse populations. He has been involved in many peer review activities, including journal articles, EPA water temperature standards, TMDL margin of safety requirements, and other water temperature modeling projects, recently including the Stanislaus River, California. Prior to work at the USGS, Mr. Bartholow was a biologist with the U.S. Fish and Wildlife Service's Western Energy and Land Use Team. Here he helped design, develop, and test geographic information systems for the analysis of coal development on wildlife and their habitats.

Mr. Bartholow has a master's degree from Colorado State University in Wildlife Biology and an undergraduate degree in Computer Science from Vanderbilt University. He has also been a Faculty Affiliate at Colorado State University.
