Swan River Restoration Project Update - Closing Out 2019

Posted on December 19, 2019 at 10:52 AM by Jason Lederer

As the books close on 2019, we reflect back on another successful year for the Swan River Restoration Project. This past year saw the opening of Reach A to the community and the continuation of gravel removal work on Reach B. In addition, we are working hard to advance restoration on the Reach B site.

The Reach A project site fared extremely well during its second full year following the completion of work. All major stream channel features, including pools, riffles, the streambed, and banks held up well. We are also seeing excellent channel development after two runoff seasons. Minor channel adjustments are occurring as anticipated and mimicking normal changes found in any natural high alpine stream. Natural erosive and depositional features, such as cut bank habitat and sandy point bars are developing nicely.

Upland and riparian plantings are also doing extremely well. Riparian willow plantings are becoming well established, helping stabilize banks and shooting up new above-ground growth.

Natural bank stabilization was critical during this high runoff year, helping keep the stream banks intact. We only saw the additional loss of one tree – a Colorado Blue Spruce – over the last year. This brings the total tree mortality to two, out of more than 100 large mature trees installed at the site a two-and-a-half years ago. Some tree mortality is expected, but this success rate is outstanding, especially given the harsh growing conditions in the Swan River Valley. In 2019, with the help of volunteers, we supplemented the tree and shrub plantings with over 500 new juvenile plants and shrubs, including Ponderosa pine, Englemann Spruce, Aspen, Woods Rose, and Lodgepole pine.

With
the native ground cover slowly becoming established, in October we were able to open the Reach A site to the public. A new natural surface trail between the Browns Gulch trailhead and Rock Island Road provides access for biking, hiking, running, angling, skiing, snowshoeing, and other passive, non-motorized recreational uses. The site is still in a fragile condition, so we ask that you tread gently and stay on the trail as much as possible.

Reach A monitoring is ongoing. During October, the County coordinated with Colorado Parks and Wildlife to conduct a fish survey both downstream of, and within the Reach A restoration reach. This is the third year CPW has surveyed the new channel during the local trout spawning season. Formal survey results for 2019 will not be available until early 2020, but initial observations indicate an extremely healthy fishery is becoming established in the new channel.

Gravel removal work also continued on Reach B in 2019 (above/upstream from the recently completed Reach A restoration site). Schofield Excavation initiated gravel removal in mid-March and over the past spring/summer/fall, removed approximately 70,000 tons of gravel. To date, nearly 310,000 tons of gravel have been removed from the Reach B site since gravel removal work started in 2015. Gravel removal will resume in 2020 as conditions allow and material demand permits. 


We have also been working to advance design on Reach B. In coordination with our ecological restoration consulting team, Ecological Resource Consultants, and numerous project partners including the Forest Service, Colorado Parks and Wildlife, Colorado Water Conservation Board, Colorado Trout Unlimited, Blue River Watershed Group, and others, the Reach B restoration design is coming into focus. Once gravel removal activities are complete, we want to ensure the design is finalized, the necessary permits are in place, and funding is available to move forward quickly.

Design


Speaking of funding, the Project saw another successful funding year, benefiting significantly from the support of our partners at Colorado Parks and Wildlife. Similar to the Reach A restoration project, the Reach B project was awarded grants from the Fishing is Fun Program ($270,000) and the Wetland/Riparian Restoration, Enhancement, and Creation Program ($150,000). We are excited to put this generous funding to good use on Reach B!


With the Reach A restoration work officially completed, we coordinated with the Colorado Division of Mining, Reclamation, and Safety (DRMS) to remove Reach A from the active mine permit boundary. In addition to reaching this exciting milestone, the Colorado Mined Land Reclamation Board honored the project with an outstanding mine reclamation award!

This will be the last blog post for 2019, but we will resume posting updates in 2020 as activity begins to ramp back up.

Reach A Grand Opening Save The Date - Tuesday, 10/15/2019 @ 1PM

Posted on October 4, 2019 at 4:44 PM by Jason Lederer

We are excited to announce that the Summit County Board of Commissioners will host a grand opening of the Swan River Restoration Project Reach A site on Tuesday, October 15th at 1 PM. The event will occur at a new trailhead along Rock Island Road. Parking is available near the intersection of Tiger Road and Rock Island Road.

In addition to providing habitat for a variety of aquatic and terrestrial species, as well as numerous other natural resource values, the site contains a new natural surface trail between the Browns Gulch trailhead and Rock Island Road providing access for biking, hiking, running, angling, skiing, snowshoeing, and other passive, non-motorized recreational uses.

Following are some photos of the new trail alignment through the site; adjacent to the new channel, as well as through the forested upland areas immediately to the south. 

We hope you are able to attend and celebrate the opening of this reclaimed piece of open space. Please do not hesitate to contact Jason Lederer at Jason.Lederer@SummitCountyCO.gov, or 970-668-4213 with any questions.

Swam River Restoration Project - Midsummer Update

Posted on July 31, 2019 at 2:47 PM by Jason Lederer

And all of a sudden it's mid-summer! If you spent much time in Summit County this spring, you are well aware of the wet, cool spring we had with accumulating snow until the end of June. All of this weather resulted in a slow start to many constructions projects around the County and, hence, a delay in gravel removal activities from the Reach B site. However, with the winter of 2019 behind us, things are back in full swing. There is even some new signage at the site explaining the work that is happening.

Summit County’s gravel removal contractor, Schofield Excavation, has removed gravel nearly to the Reach B eastern property boundary. Once they reach the property limit, they will begin working their way out of the site, establishing final rough grades along the way.

With the Reach B gravel removal “light at the end of the tunnel” coming into focus, we are gearing up to complete the final restoration work as soon as possible once the removal work is complete. This summer, in coordination with the County’s ecological engineering consultant, Ecological Resource Consultants (ERC), we are working to optimize the conceptual restoration design by taking into account new groundwater information, post-gravel removal surface grades, opportunities for onsite wetlands creation, and other factors. 

This year's historic snow pack and runoff cycle really tested the integrity of the constructed channel and floodplain in Reach A. Two and half years following the completion of major construction, we are happy to report that the new stream fared quite well with riffles, pools, banks, and other features functioning as intended. In fact, we are even starting to see new habitat features, such as sandy point bars, form naturally.

The Reach A site did experience some erosion at the temporary overflow channel where seasonal runoff passes beneath Rock Island Road. However, in coordination with Schofield Excavation, we were able to quickly stabilize the location utilizing large boulders and gravels from the Reach B site. This temporary overflow channel was designed solely to convey spring runoff and will be abandoned when the future upstream Reach B channel is permanently connected with Reach A.

This year's moisture has also helped riparian and upland vegetation flourish, with natural recruitment of several native plant species including rushes, grasses, sage, and others species native to the valley.

Stay tuned for more exciting announcements about the Swan River Restoration Project site later this year.
