Rossum to Wilson Ave River and Rist-Goss Ditch Improvement Project

Project Description

The Rossum Drive to Wilson Ave River Improvement projects is being constructed in conjunction with Rist-Goss Ditch Improvement Project to deliver a combined two miles of river restoration and the removal of a 6 ft high cement diversion structure. This exciting project, implemented by Big Thompson Watershed Coalition on City of Loveland and Loveland Ready Mix land, boasts multiple benefits for both wild and human communities of the Big Thompson through the City of Loveland. Long term City Parks & Open Space development plans to eventually open a new portion of the property at Medina’s Crossing to the public. This project also provides improvements to the City’s Namaqua Park, adding to the enjoyment of this easily accessible riverside park. This project will replace the aging cement diversion with natural water features such as large rocks, riffles and pools, improve bank stability, reconnect the river to its floodplain, and install native plant species, and will improve wildlife habitat and fish passage upstream. The project will also ensure continued water delivery to downstream water rights holders, and also provide flood protection to nearby private lands and infrastructure. The project is being completed in coordination with Larimer County, who is replacing the Namaqua Road bridge and will provide greater resilience to the road and bridge infrastructure.

Construction began in January 2019. Initial reconstruction and revegetation efforts expected to be completed by June 2019.

Get Involved

Project partners BTWC and the City of Loveland were awarded additional grants from GOCO and Colorado Watershed Assembly Healthy Rivers Fund in 2018 to carry out additional community volunteer opportunities to plant and ensure success of new vegetation along 7 acres of native plants within the project’s floodplain. Come join the effort and help us install 1,000s of new plants at this site summer and fall 2019

Rossum and Rist-Goss

Construction Progress

Rist Goss Area – March 2018

The aging Rist Goss ditch is made of cement and currently accumulates debris and prevents sediment and fish passage. Once removed, the current diversion infrastructure will be replaced with a series of large rocks within the river that help divert water into the ditch for downstream water users, while promoting better river function.

Construction is UNDERWAY

Construction on the project is underway. Check back for photos of progress and conditions after construction is complete.

This video from our construction subcontractor Flywater, shows demolition of the existing Rist Goss Diversion. The Big Thompson Watershed Coalition project will be replacing the aging infrastructure with a more river and fish friendly diversion that will continue to deliver water to downstream water users.
