Big Thompson Fish Passage Design (CO) 2014-2016


OVERVIEW: The Big Thompson River was heavily impacted by a massive flooding event in September 2013, causing significant damage to dozens of ditch diversion structures. Fish passage and habitat became a huge recovery objective, shared by municipalities as well as environmental interests and recreational users. AloTerra was hired by Colorado Trout Unlimited (CTU, USFWS, CPW funders) to produce designs for fish passage of trout and non-trout species for three ditch diversions on the river below the canyon mouth. AloTerra collaborated with agencies, technical teams, and four ditch companies to develop 30% designs for two structures, and ultimately, conceptual designs for five ditch diversions to be supported by ditch companies, landowners, and the environmental/natural resources community. We continue to work proactively with these partners to develop a funding strategy for the final design/build phase of two fish passage sites.


AloTerra was responsible fo project feasibility, designs from concept-30%, project team development & coordination, project management, stakeholder engagement activity.
