The Boulder Creek Project is located in northwest Montana, within Lake County, and its entire drainage of 7.1 square miles is within the Flathead Indian Reservation. Boulder Creek drains into Flathead Lake from the Mission Range of the Rocky Mountains. The facility is owned by the Confederated Salish and Kootenai Tribes, and is managed and operated by S&K Holding Company (SKHC), which is a for-profit business development corporation, wholly owned by the Confederated Salish and Kootenai Tribes.
The Confederated Salish and Kootenai Tribes are comprised of the Bitterroot Salish, the Pend d’Oreille, and the Kootenai Tribes. In 1855, the Hellgate Treaty established the Flathead Reservation and the Tribes were relocated to their current home. The Flathead Reservation contains 1.3 million acres but over 500,000 acres passed out of Tribal or Tribal Member ownership with the advent of homesteading in the early 1900s. The Tribes are federally recognized and governed by a Tribal Council.
In 1982, the Tribes built Boulder Hydro as a means of promoting economic development. SKHC was created in May 1992 under the laws and constitution of the Confederated Salish and Kootenai Tribes. The Tribal Council serves as the Shareholder for SKHC. A five-member Board of Directors appointed biannually by the Shareholder provides direction. The mission statement of the company is: Promote economic independence by maximizing economic opportunities for the Tribes and the Tribal Membership in a culturally appropriate manner.
The project includes a diversion, penstock, intake area, powerhouse, and tailrace. Boulder Creek flows much of its journey to Flathead Lake underground. A portion of Boulder Creek surfaces approximately 100 yards upstream from the impoundment. The 5-foot-tall, 16-foot-long diversion utilizes all of the flow in all but the highest flow periods occurring during the spring runoff or during a significant runoff event. Even with full dewatering of the stream, water flow reappears less than 10 yards below the diversion structure even in the lowest flow periods of the year and the flow continues to grow and recharges itself to at least 0.5 cfs within 200 feet below the diversion. Water is diverted to 3,650 feet of buried piping and penstock and conveys flows to the powerhouse. The powerhouse contains a single nozzle impulse type turbine with a synchronous generator having a 350-KW maximum generating capacity.
The project operates in a run-of-river mode and impounds a 0.15-acre reservoir with a net storage capacity of 0.025 acre-feet. The project provides a minimum flow of 0.5 cfs below the diversion into the 0.71-mile-long bypass reach, and a maximum of 8 cfs is diverted to the powerhouse. With no fish present within Boulder Creek, the Tribes’ Division of Water Department concluded this flow regime was appropriate for wildlife and aquatic resource support.
Waters within the project reach are designated A-1 and the project has strictly maintained that classification upstream and downstream of the project area. In addition, as part of the original agreement for an easement to the powerhouse location, the Tribes installed a collection pipe and built a pump house to serve local residents as their primary source of drinking water for their homes. This location is approximately 40 yards downstream from the powerhouse and pumps Boulder Creek water to approximately 10 homes in the vicinity. Boulder Creek, to this day, maintains extremely high-water quality.
Boulder Creek has historically not been supportive of fish populations. The lower stream reaches have extreme elevation barriers in the first 100 yards above its mouth on the east shore of Flathead Lake. The Fisheries Department and Tribal staff have yet to observe any fish species in the stream.
The project lands consist of less than an acre. A 50-foot shoreline conservation buffer zone surrounds the impoundment and prohibits woodcutting near the stream.
Threatened or endangered species potentially present in the project vicinity include bald eagle, Canada lynx, grizzly bear, North American wolverine, and whitebark pine. In addition, the threatened bull trout are found in Flathead Lake and gray wolves are present within the Reservation, but not in the project vicinity. The Tribes are actively involved in a Bull Trout Recovery Plan, a Grizzly Bear Recovery Plan, and a Gray Wolf Recovery Plan. These efforts have resulted in population increases for grizzly bear and gray wolf populations within reservation lands. None of these species have been observed in the project area but lands may be used by transient individuals.
Prior to construction of the project, the Flathead Culture Committee, Kootenai Culture Committee and Montana Historical Society were consulted to identify any locations or items of cultural importance within the project area and none were identified. The groups concluded that the construction and operation of the project would not have any impact on any cultural, archaeological, or historical resources in the project area.
There are no recreation facilities associated with the project which is located near the base of the Mission Mountains within a designated Tribal wilderness area. Tribal members can hunt and gather wild berries near the project. The species harvested in this area include elk, whitetail and mule deer, turkey, and grouse. Firewood harvesting is also prevalent in the area. There are no restrictions on access to the land around the project and no associated costs to recreate or have access to the land where the facility is located. A Tribal Recreation Permit is required for non-tribal members to access the lands.
There are no facility-specific conditions in the current Certificate.
