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.

“I want to tell you how much we have enjoyed hosting your drill crew this summer. We have had work crews in the past and were a little skeptical about taking on a drilling crew with all of the stories we have heard.

I'm here to tell you that your drillers are definitely a cut about the rest. Each and every one of them we've had on the job here are fine respectful, thankful, kind, considerate, gentlemen. They are to be commended for the new image of the Alaskan Driller that they portray.

I would welcome them back at the Lodge any time, whether on work or pleasure.
Thanks again for hiring a great bunch of guys.”
