Board of Directors

GGWC is governed by a Board of Directors broadly representative of our watershed community. Members represent agricultural producers, irrigators, non-governmental organizations, sub-watershed groups, recreationists, local government, natural resource managers, business, and other watershed interests. Board business meetings are usually held the second Tuesday of each month at 5:15pm – 7:00pm at the City of Bozeman’s Professional Building at 20 E. Olive (unless otherwise noticed). All are welcome. Directors serve 3-year terms; vacancies are filled by election at the annual meeting in January. Board meeting agendas and minutes can be found HERE.

Board members are asked to serve on at least one of GGWC’s four Committees – Executive (Officers), Development, Education & Outreach, and Water Resources. Non-Board members may also serve on committees upon the invitation of the committee chair(s).

2018 Leadership Team

Lilly Deford –  Chair, Executive Committee, Water Resources Committee, Education & Outreach Committee, Development Committee. Lilly comes from a big farming family in Maryland, where she grew up exercising race horses, bailing hay, and welding farm equipment. She has made a home in Bozeman after coming here for school in 2006, and has since graduated with her undergraduate and graduate degrees in Civil Engineering. Her studies focused on soil and water as they apply to agriculture, from irrigation and streams, to nutrient cycling and waste management. With her heart and roots in farming, and her technical background, Lilly looks forward to working with GGWC to create dialogue between different interest groups. She believes that we can all find common ground in our dependence on clean water, and that our efforts to protect the resources in the Gallatin watershed are stronger together. In addition to serving on the board, Lilly is currently working in construction, both helping run a small roofing and siding company, as well as rebuilding her own house in downtown Bozeman.

Peter-1-210x300Peter BrownViceChair. Executive Committee, Water Resources Committee.  Peter grew up on a family ranch in the Helena Valley. Those formative years instilled in him a deep respect for the contribution that Montana farmers and ranchers make to our rural communities and our collective heritage of Montana’s wide open spaces. This has led to a career in private land conservation and his most recent position with Gallatin Valley Land Trust, where he helps farmers and ranchers protect their family ranch by establishing and stewarding conservation easements. Through his work, it has become apparent that water is a very hot topic in Montana; where having not enough can turn into too much with one mid-summer thunder storm. Peter received his MS in Resource Conservation from the University of Montana. He currently lives in Bozeman with his wife, and regularly travels back home to Helena to visit family and help out on the family ranch.

Meryl Storb –  Development Committee, Co-Chair.  Meryl is a Ph.D. student at MSU in the Land Resources and Environmental Science Department – working in the Payn Watershed Hydrology Lab. She started her Ph.D. during the fall semester of 2014. Her dissertation research is focused on understanding how water quality and quantity may change in the Big Sky watershed with ongoing development and impacts from climate change. Prior to returning to graduate school, Meryl spent six years working for an environmental consulting firm in Missoula, MT. She worked on a range of projects that were focused on groundwater, in the western US, Canada and West Africa.  Before she entered the world of consulting Meryl obtained a B.S. from the University of Montana (UM), in Environmental Geology (2008). While at UM she worked as a research assistant and an environmental health technician (Missoula Dept. of Water Quality), working on several aspects of the Milltown Dam Removal Superfund Project in Bonner, Montana.
