Mill Pond reopening means more summer rec opportunities on Colville NF

A new channel is being formed in the floodplain of what was previously Mill Pond

COLVILLE, Wash. (March 4, 2019) – Summer promises exciting new recreation opportunities on the Colville National Forest, as the Mill Pond Historic Site and Campground reopens after a two-year closure.

This site has been closed since July of 201,7 when construction began to remove Mill Pond Dam and restore surrounding habitat.

The campground is scheduled to reopen before Memorial Day, with 10 upgraded campsites, including new food storage lockers, and major improvements to roads, parking, signage, and bathroom facilities to better support visitors’ outdoor experiences.

The Mill Pond Historic day use site and a new trail system are expected to re-open by June 27, 2019.

The project is being performed by Seattle City Light on the Colville National Forest, as required by the Settlement Agreement for the Boundary Hydroelectric Facility License issued by the Federal Energy Regulatory Commission in 2013.

The log crib dam that formed Mill Pond was constructed in 1909 by the Inland Portland Cement Company, and was replaced by a concrete dam in 1921, but had not been used for electricity generation in many years. Seattle City Light agreed to perform the removal work as part of an agreement to re-license a different dam.

Two new loop trail systems will be available around the old pond site, including two footbridges spanning the old dam site and the upstream channel. The new trails connect to about three miles of existing trail in the area.

The Mill Pond Historic Site day use area will also be renovated with a large new picnic pavilion, which includes a community fireplace, new picnic tables, and accessible parking.

New interpretative signs and kiosks that tell the history of the site will be installed by late fall of 2019.

Visitors to the area will find the landscape of the old pond site has been transformed during the closure. Most of the sediment in the pond was flushed downstream with strong Sullivan Creek flows in the spring of 2018, exposing the pre-dam ground surface of the Sullivan Creek floodplain.

Throughout the summer and fall of 2018, a natural riverine ecosystem was shaped with multi-thread stream channels and extensive logjams to provide high quality fish habitat and spawning areas.

During the fall, thousands of locally sourced shrubs, trees, and grasses were planted in five different planting zones around the old pond site.

As warmer weather sets in this spring, the site will begin greening up and the final steps of the site restoration will be complete.

  • I’m confused…. The picture looks as though Mill Pond is now gone? I thought the dam was upstream from Mill Pond. Is Mill Pond still there?

    • Hi Dave – yes, the dam created the “mill pond,” so now that the dam has been removed the pond that formed above the dam is no longer there. The project restored Sullivan Creek to a more natural stream flow / wetland area from the pond down through Outlet Creek. It does mean the pond as it existed before is no longer – but the results will improve living conditions and suitability for many fish and other aquatic wildlife.
