Adaptation to minimize the joint impacts of climate change and the management of hydraulic infrastructures on fish and fish habitat

在气候变化的背景下，对水库下游向环境流动的放水进行管理变得越来越复杂，需要更好的预测和决策工具。该提案旨在获取新知识，开发/改进气候变化背景下的鱼类资源管理工具，以减轻水温可能升高对鱼类的影响。该方法基于三个子部分：1）改进和调整水文，水力和水温模型，以适应水库管理的背景。2)获得关于Nechako系统中存在的三种重要鱼类的生理和温度要求的新关键知识，本研究正在进行。3)使用气候变化情景来预测水库放水管理中可能需要的潜在变化。对淡水养殖业的好处包括将从加拿大西部一个重要的受管理流域的水温要求的第一次多物种研究中获得的见解，改进的流量和水温管理建模工具，以及具有跨学科经验的高素质人员的培训。

In the context of climate change, the management of water releases downstream of reservoirs to maintainenvironmental flows is becoming more complex and better tools are required for forecasting anddecision-making. This proposal aims at acquiring new knowledge and developing/improving tools for reservoirmanagement in the context of climate change, in order to mitigate the impacts of potential increased watertemperature on fish. The approach is based on three sub-components: 1) Improve and adapt hydrological,hydraulic and water temperature models to the context of reservoir management. 2) Acquiring new keyknowledge on the physiology and temperature requirements of three important fish species that are present inthe Nechako system, where this study is taking place. 3) Use climate change scenarios to anticipate potentialchanges that may be required in the management of reservoir water releases. The benefits for the Canadianindustry include insights that will be gained from a first multi-species study of water temperature requirementsin an important managed watershed in Western Canada, improved modelling tools for flow and watertemperature management and training of highly qualified personnel with cross-disciplinary experience.
