The project consists of three parts: a bypass channel to reconnect the aquatic habitat downstream from the habitat improvement. When completed, it will directly benefit 30 miles of the Colorado River and The first part of the project, known as the Colorado River Connectivity Channel, will create a bypass around Windy Gap Reservo necting channel, at an estimated cost of $23.5 million, will reconnect the Upper Colorado and Fraser Rivers to the main stem of the the river. The connecting channel is expected to greatly improve the valuable trout fishery downstream all the way to the popular Ke This huge undertaking could not be possible without geotechnical investigations, which yield information to make recommenda September 2020, they drained Windy Gap Reservoir to prepare for testing. Releasing water from the reservoir into the Colorado Rive struction investigations. In November, the critical geotechnical investigations got underway as Northern Water collaborated with AECO holes and 15 test pits at the dam and reservoir site were identified by AECOM. The actual tests performed and the number of each t further understand the characteristics of the construction site. Multiple piezometer wells were also installed to monitor groundwater e Commenting on Northern Water and AECOM’s joint geotechnical investigations, Kevin Lock reported they sent the soil samples construction, including seismic analysis, surveying, dam design, slurry trench, and diversion structure foundation and walls. Lock said with the majority of construction being conducted in 2022, with some follow-up in 2023. We hope to have water flowing through the n C&G
