New Insights For The Future Of Lake Champlain: Practical Approaches And Useful Tools For Grappling With Uncertainty And Weighing Trade-Offs In Watershed Management., Philip Halteman
Graduate College Dissertations and Theses
The effective management of non-point source nutrient pollution continues to prove elusive. Though the scientific literature is unequivocal that all anthropogenic land uses contribute to non-point source (NPS) pollution, variable levels of contribution over time and across location and complex relationships between cost and effect make finding technologically effective management solutions difficult. In addition, these solutions are implemented in a world of scarce resources, diverse and often competing concerns and values, and intense public scrutiny. Clearly, making the best possible decision about how to manage NPS pollution under these conditions is not simple. My overarching goal was to develop and …

Repeated erosion of over 7,000 miles of unpaved roads in Vermont is degrading water quality and draining limited town budgets. Best Management Practices (BMPs), including stone-lined ditches, turn outs, check dams, revetments, culverts and vegetative controls, are recommended by the Vermont Department of Transportation as low cost means of reducing the sediment and phosphorous run-off from backroads. However, their effectiveness, longevity and cost benefit are unknown. To address this gap, I assessed 100 BMPs at 43 erosion control projects constructed between 2005 and 2012 with funding from the Vermont Better Backroads program. BMP condition was compared to environmental factors that …

The Champlain Sea/Lake Champlain Transition Recorded In The Northeast Arm Of Lake Champlain, Usa-Canada, Ashliegh Theresa Belrose
Graduate College Dissertations and Theses
Sediment accumulated on a lakebed archives information about past climate and changes in the regional environment. Previous studies (Burgess, 2007; Koff, 2011; Palmer, 2012) in the Northeast Arm of Lake Champlain, specifically Missisquoi Bay and Saint Albans Bay, showed a period (~9,400 - 8,600 yBP) of elevated organic matter deposition in both bays, indicating a productive event that pre-dated any possible anthropogenic influence. However, the record was abruptly cut off and any documentation representing the span of time leading up to this event was not found. The elevated organic matter levels were explained as being the result of a warm, …
