Construction Update – 4/11/17
Heavy construction is complete on the Coalition’s demonstration project at Sylvan Dale Guest Ranch (SDGR) and the City of Loveland Water Treatment Plant. Over the next few weeks, the design-build team will be doing revegetation work in areas disturbed by construction and planting some willows along the work areas near the City’s Water Treatment Plant.

Construction Update – 4/3/17
Construction at Sylvan Dale Ranch is underway and expected to continue this week. The team is currently working on the main-stem of the Big Thompson and a side channel on the Ranch’s property. Pictures show work on a riffle-pool sequence, which adds structure to the river channel, creates a more natural river and provides improved fish habitat. Once heavy construction is complete this week, the design-build team will work on revegetation of both the Sylvan Dale and City of Loveland reaches where construction occurred.
Construction Update – 3/27/17
Construction on the Sylvan Dale and City of Loveland Water Treatment Plant is underway. As of 3/27/17, the project team has finished construction on the Water Treatment Plant reach. Work will begin this week on the Sylvan Dale reach of the project.
· In the upper portion of the City Water Treatment Plant reach, the material deposited in the center of the channel has been graded into a point bar on the right side of the river (when facing downstream). A low-flow thalweg was created on the left side of the river. Habitat boulder clusters were placed throughout the low-flow channel. At the downstream end of this section, the channel was regraded into a gentle longitudinal slope to match existing.
In the lower section of the City Water Treatment Plan reach, the island has been regraded into a point bar and the side channel was filled in. The bar was armored with large native cobble. A grade control structure consisting of large native cobble was constructed in the center of the bar (perpendicular to flow) to prevent undercutting and erosion. On the left side of the river, a single riffle-pool-glide feature was built to design elevations. Native soil was placed in the voids of existing riprap bank protection to facilitate future willow staking.
