REGIONAL — The National Park Service is proposing to replace a deteriorating underwater power line that supplies electricity to the historic Kettle Falls district at Voyageurs National Park, a move officials say is necessary to prevent outages and reduce safety risks for visitors and staff.
The proposal is outlined in a Floodplain Statement of Findings, a required federal compliance document because part of the electrical line runs beneath Namakan Lake. While the report centers on floodplain regulations, the heart of the project is much more practical – keeping the lights on at one of Voyageurs National Park’s most iconic destinations.
The existing high-voltage cable was installed in 1987. According to the report, the underwater line now has a fully corroded exposed neutral braid and has been struck by lightning multiple times over the years. With the neutral wire compromised, the system has lost grounding protection, increasing the likelihood of outages and equipment damage.
The power line serves the historic Kettle Falls Hotel, guest villas, restaurant, and related facilities operated by concessioners. Those facilities draw thousands of visitors each year.
When power goes out, restrooms and showers may close. The restaurant loses refrigeration and freezer capacity, creating potential food safety concerns. The hotel’s electric fire suppression pumps cannot operate without electricity.
Park officials note that there is currently no backup power supply. Extended outages not only disrupt visitor services but also pose safety risks and potential revenue losses for the concession operation.
The proposed project would replace the main underwater cable and transformer equipment and add a backup generator at Kettle Falls. The generator would allow the hotel and related facilities to continue operating during temporary outages.
Officials considered two options, rebuilding the existing distribution system or developing a new hydropower source at the Kettle Falls Dam. The hydropower option was rejected due to regulatory complexity and operational constraints. Replacing the existing system was determined to be the simpler and more reliable solution.
Because the primary cable runs underwater, the project falls within a regulated floodplain, triggering the need for the floodplain statement. The document also references the high-water event of 2022 and notes that the regulatory flood elevation used for planning is higher than the highest recorded water level on Namakan Lake.
Park officials emphasize that the project does not expand development at Kettle Falls but instead replaces aging infrastructure already in place as essential maintenance to ensure reliable service.
