As the climate changes, the natural water systems upon which Canadian's rely are changing too and small water utilities in Atlantic Canada have limited resources with which to assess the sustainability of their water supplies. The Centre for Water Resources Studies (CWRS) at Dalhousie University will partner with the Town of Yarmouth, Nova Scotia, and the Atlantic First Nations Water Authority (AFNWA) to fill knowledge gaps related to the Lake George Watershed Protection Area, which provides source drinking water to the Town of Yarmouth, Acadia First Nation, and parts of the county. Lake George was last studied in the 1960s and a recent drought has raised questions about climate change impacts on source water. The goals of this partnership will be to: (1a) Accurately delineate the watershed boundaries and landcover using the latest scientific techniques; (1b) Conduct a comprehensive water budget analysis to understand the capacity of the watershed to meet human and ecological needs; (2a) Factor in climate projections to understand watershed vulnerabilities; and (2b) Link the hydrologic projections to a water safety plan (WSP) risk-assessment framework and suggest key hydrologic indicators to support climate change planning for small Atlantic Canadian water utilities and First Nations communities. This project will contribute to municipal and First Nations water policy and planning, and one Master's student will be trained. The expected outcomes of the project will include the water budget analysis and a guidance tool to help other municipal and First Nations systems apply hydrologic projections and WSP approaches to characterize and mitigate risks to source water. This tool will be instrumental for small systems in the Atlantic region with limited financial resources to prioritize and respond to the impacts of climate change on drinking water security.

随着气候的变化，加拿大人所依赖的自然水系统也在发生变化，加拿大大西洋沿岸的小型供水公司评估其供水可持续性的资源有限。达尔豪西大学的水资源研究中心（CWRS）将与新斯科舍省雅茅斯镇和大西洋第一民族水务局（AFNWA）合作，填补与乔治湖流域保护区相关的知识空白，该保护区为雅茅斯镇、印第安纳第一民族和该县部分地区提供饮用水源。乔治湖最后一次被研究是在20世纪60年代，最近的一次干旱引发了人们对气候变化对水源影响的质疑。这一伙伴关系的目标将是：（1）利用最新科学技术准确划定流域边界和土地覆盖;（1）进行全面的水资源预算分析，以了解流域满足人类和生态需求的能力;（2）将气候预测因素考虑在内，以了解流域的脆弱性;以及（2b）将水文预测与水安全计划风险评估框架联系起来，并提出关键水文指标，以支持加拿大大西洋沿岸小型供水公司和原住民社区的气候变化规划。该项目将有助于市政和第一民族的水政策和规划，并将培训一名硕士生。该项目的预期成果将包括水资源预算分析和指导工具，以帮助其他城市和第一民族系统应用水文预测和水资源项目方法来描述和减轻水源风险。这一工具将有助于大西洋地区财政资源有限的小型系统优先考虑和应对气候变化对饮用水安全的影响。
