PUBLIC LANDS -- The National Park Service may require the removal of 25 private cabins that have been built and upgraded over many years within the Lake Roosevelt National Recreation Area northwest of Spokane.

That’s one of three options in an environmental assessment released Thursday by the agency. The other two options would allow the private cabins to remain under five-year leases. The public will have 45 days to comment before the Park Service is scheduled to make a decision.

The cabins were authorized in the 1950s to encourage recreational use of the lake. They are located at Rickey Point and Sherman Creek. If the removal option is chosen, the owners would have to remove the cabins when the current leases expire.
