Mr. Fischer is a true team leader through alternative thinking, exemplary motivation, and positive mind set.

Mr. Fischer has over 30 years experience as a project engineer/project manager and has guided the Company to become a preeminent leader in hydroelectric design and construction. Thom earned his Bachelor of Science in Transportation Engineering/Civil Engineering from California Polytechnic State University, San Luis Obispo and also studied Arctic Engineering at the University of Alaska in Anchorage. He is a licensed professional engineer in the states of Alaska, California, and Washington.


Mr. Steven C. Marmon
Vice President

Mr. Marmon joined Whitewater Engineering in 1992, and he continues to provide construction and project management for design-build hydroelectric projects and civil projects. Project management responsibilities include: estimating, scheduling, quality control, sub-contract buyout, equipment and material procurement, state and federal agency permit and license coordination, and environmental compliance. Steve brings tremendous logistical and planning experience in constructing difficult projects in remote areas of Alaska including the Black Bear Lake, Goat Lake and Power Creek hydroelectric projects, and the Tyee transmission line improvement project. He most recently managed a four year effort to license the GIbson Dam Hydroelectric Project resulting in FERC issuing a 50 year license to construct and operate the project.


Mr. Christian D. Spens
Licensing Manager

Mr. Spens has over 26 years of land use and environmental planning experience. He has worked in the hydropower industry for the past six years. He has worked for municipal and tribal governments as well. He served for ten years as the SEPA Official for the City of Bellingham, WA. Chris managed the day to day land use permitting activities for development within the city for over 6 years. He was the project manager for development of clearing, grading, wetland, stream, watershed protection, and power generating facilities ordinances. He has been involved in many aspects of natural resource management ranging from forestry and watershed protection to restoration of contaminated waste sites. Chris graduated from Western Washington University in 1983 with a Bachelor of Science degree in Freshwater Sciences.


Ms. Miranda Eckert, PE
Civil Engineer

Miranda Eckert specializes in engineering design and project management. Ms. Eckert develops hydraulic and hydrologic models of rivers and in-stream structures to support project design and site development. She manages projects under both the FERC licensing framework and the provincial licensing framework in Canada. Her feasibility studies are used to acquire grant funding, evaluate the purchase and sale of renewable assets, and determine design parameters for heavy civil projects. Ms. Eckert graduated from Humboldt State University in Arcata, CA with a Bachelor of Science in Environmental Engineering. Miranda’s knowledge of analytical modeling, hydrology, hydraulics, and geospatial analysis along with her passion for renewable energy make her a valuable asset to the Tollhouse Energy team.
