The aging Mactaquac Hydroelectricity Generating Station is one of Canada's largest dams and it has reached the end of its service life. NB Power (NBP) worked with the Canadian Rivers Institute, University of New Brunswick to generate the aquatic science required to support NBP's decision to renew the dam infrastructure in the short-term with a longer-term solution of rebuilding or removing. In Phase 2, a new research collaboration generates the science to support an environmental impact assessment, to provide fish passage solutions for the dam and the whole river, and to provide guidance for managing the river's flow in our changing climate. This project is the largest, planned dam renewal in the world. The supporting science builds on the long-term Mactaquac Aquatic Ecosystem Study (MAES) designed to explore the potential consequences of NBP's activities for the river and its reservoir. The study describes the river ecosystem and its goods (e.g., animals and plants) and services (e.g., water quality) and asks the question, what are the environmental challenges and opportunities in the short- and long-term of the dam renewal. The research establishes baseline environmental conditions, develops appropriate indices for environmental monitoring, and predicts flow, sediment, and temperature regimes. This information is used to map habitats for the animals and plants today, changes during construction, and for the future of flow management by NBP including addressing climate change. MAES is an investment by NBP in the research and development required to sustain its hydropower business model in a changing world of greening economies. This partnership acknowledges the emerging economic significance of ecosystem goods and services and will be a precedent-setting case study for Canada. MAES will create a template of approaches and methods that will facilitate the incorporation of aquatic ecosystem science into informed decision-making and management for future hydropower projects across Canada and globally.

老化的Mactaquac水力发电站是加拿大最大的水坝之一，它已经达到了使用寿命的终点。国家电力公司（NBP）与加拿大河流研究所、新不伦瑞克大学（University of New Brunswick）合作，开展水生科学研究，以支持国家电力公司的决定，即在短期内更新大坝基础设施，并采取重建或拆除大坝的长期解决方案。在第二阶段，一项新的研究合作将为环境影响评估提供科学支持，为大坝和整条河流提供鱼类通道解决方案，并为在气候变化的情况下管理河流提供指导。这个项目是世界上最大的水坝更新计划。支持科学建立在长期的Mactaquac水生生态系统研究（MAES）的基础上，该研究旨在探索NBP的活动对河流及其水库的潜在影响。该研究描述了河流生态系统及其产品（如动物和植物）和服务（如水质），并提出了一个问题，即大坝更新的短期和长期环境挑战和机遇是什么。该研究建立了基线环境条件，开发了适当的环境监测指标，并预测了流量、沉积物和温度状况。这些信息用于绘制动物和植物的栖息地，建设过程中的变化，以及NBP未来的流量管理，包括应对气候变化。MAES是NBP在研究和开发方面的一项投资，该投资是为了在不断变化的绿色经济世界中维持其水电业务模式。这种伙伴关系承认生态系统产品和服务的新兴经济意义，并将成为加拿大的先例案例研究。MAES将创建一个方法和方法模板，促进将水生生态系统科学纳入加拿大和全球未来水电项目的知情决策和管理。
