Biography

Mr. Johnson has over 25 years experience successfully managing research projects related to the environmental effects of hydroelectric energy production. Mr. Johnson was the technical manager for hydroacoustic monitoring and evaluation studies during the development of the surface flow bypass system at the Wells Dam from 1983 – 1992, which is arguably the most efficient smolt bypass in the Columbia basin. He served as manager of the Technical Services Division at BioSonics, Inc. before moving to the Bonneville Power Administration as a fisheries biologist. At BPA, Mr. Johnson worked to integrate needs for safe fish passage with the demand for hydroelectric generation. This led to Mr. Johnson being hired at PNNL to manage fish passage evaluations and bioengineering projects on the Snake River. He continued this type of work for BioAnalysts, Inc. before returning to PNNL to work on estuarine studies. Mr. Johnson currently manages projects related to research, monitoring, and evaluation in the lower Columbia River and estuary.
