Our Projects

Tyee Lake Hydroelectric (IECO)

The investigation included using a mini-sub to map the lake bottom (>100’ deep) to locate a suitable lake-tap entrance, seismic studies for the control dam foundation, geologic mapping of the surface and subsurface (diamond drilling), selection of penstock, powerhouse, tunnel locations and a natural hazard assessment.

Solomon Gulch Hydroelectric Project (IECO)

Drilling of dam abutments for final design, mapping and characterization of penstock corridor, material site identification, and road alignment.

Terror Lake Hydroelectric Project (R.W. Retherford & Assoc.)

Drilling and subsurface evaluation of dam abutments and tunnel alignments, geologic mapping of penstock, road and transmission routes.

“While one of our main objectives is to provide our clients with excellent geologists, we are much more than a temp agency. We do not merely keep geologists in the queue; we play an integral part in their professional growth process. We are committed to both our clients and our employees and strive to find the best fit for all involved.” Robert Retherford, President
