Restoring Migration Routes for Trout
One of our primary goals is to improve conditions for trout by improving overall ecosystem health and functionality–restoring habitat, stream flows and water quality–and by making structural improvements in or to the stream, such as installing fish ladders, step-pools, and screens. A healthy population of Teton River Cutthroat depend on migrating up tributary streams to spawn. For tributaries that have intact and productive populations of native trout, restoring connected migration routes free of obstacles, impediments, or entrapment, is how we improve the chances for reproductive success and the persistence of this iconic species.
Irrigation Diversions/Fish Screens
There are numerous canals and irrigation diversion structures on each of the major tributaries in Teton Valley. Several of the diversion structures are similar to small dams that create barriers to fish migrating up and downstream at certain flow levels. Several of the canals in the valley have high entrapment potential, meaning that fish are attracted to the canals and can become stranded, once headgates are closed. Irrigation diversion structures can also be outdated and need improvement to function properly for local irrigators to receive their water right without trapping fish. FTR started working with willing individuals and canal companies in 2006 to replace old diversion structures with fish-friendly headgates, as a win-win for farmers and fish.
Fish Ladders/Step-pools
In 2005, FTR conducted an assessment of potential barriers to fish passage, and prioritized improving those that created a significant obstacle for fish swimming upstream to spawn. Depending on location and feasibility, fish ladders are one kind of structure to aid migrating fish past existing barriers. Where possible, FTR has installed step-pools, which act as a more “natural-looking” fish ladder that creates holding water for trout, provides stream stability/structure, moderates gradient, and conveys sediment and flows.


























Todd began spending significant time in Teton Valley after he and his family built a home in Driggs in 2012, and then settled full time in 2014. He is graduate of the University of Vermont and has a MBA from Boston University. His career has been spent building high tech companies and managing venture capital investments back in Cambridge MA and New Hampshire. He currently sits on the non-profit board of the Putnam Foundation, and previously on the board of Mountain Bike the Tetons . He is an avid fly fisherman, hunter, mountain biker and skier. He and his wife Astrid stay busy trying to keep up with their three young adult children Quimby, Tucker and Addie and their dogs Cedar and Ollie, and can be seen out often on the river and trails in and around the valley.
Brian was born and raised in Reno, Nevada and introduced to fish and fishing at the age of 2 and hasn’t looked back since. After spending his youth exploring and fishing his way through the Sierra’s and surrounding areas, he moved to Oregon to attend Oregon State University. He fortunately limited out on King salmon the day of his last final and was able to make it back to campus in time to complete his exam and subsequently earned a B.S in Fisheries Biology. Brian has worked extensively as a fisheries biologist throughout the West and Alaska on projects that ranged from listed Lahonton Cutthroat Trout to the docile Sleeper Shark in Alaska. Brian first sort of moved to Driggs in 2005 working for Aqua Terra Restoration constructing stream and wetland restoration projects throughout the area, while still going back to Alaska for fisheries research survey’s in the Bering Sea and Gulf of Alaska. Brian spends his free time outside and with his girls Jenny (wife), Brook, Maggie (daughters), and their black lab, Maple Heart Van Winkle Syrup.




Hannah grew up exploring the coastal and mountain ecosystems of Maine, canoeing on lakes and rivers, and wading through mud to explore inter-tidal, estuary habitats. This love of the natural world drove Hannah to study Environmental Studies and Geography at Middlebury College in Vermont, where many courses, including her senior thesis, focused on the Lake Champlain watershed. In 2012, Hannah moved to the Tetons to pursue a career in the environmental nonprofit sector and indulge her passion for the mountains and rivers of the West. While working in the Tetons, Hannah pursued an MBA in Sustainable Business from Green Mountain College, graduating from their online program in 2019 with a background in marketing, stakeholder engagement, and systems thinking. Hannah is thrilled to join FTR after nine years at Teton Science Schools as an educator, administrator, and fundraiser and is excited to connect more people to FTR’s impactful work in Teton Valley. In her free time, Hannah can be found trail running, mountain biking, skiing or fishing with her husband, two black labs, and her new baby girl, born in February.
