The release of chemically complex municipal and industrial effluents into aquatic environments is a global-scale issue that is rapidly increasing with population growth and increasing water consumption. Effluent release has complex and poorly-defined impacts on aquatic ecosystems, with potential to negatively impact public health. To address these uncertainties, we have designed a multidisciplinary research program that defines organismal to ecosystem responses to complex effluent loading in a socio-economically important watershed in southern Alberta. Like many effluent-receiving watersheds, the Frank Lake wetland in the Upper Little Bow River watershed represents a complex management scenario. Like other watersheds, this system is faced with degradation of habitat and water quality due to its long history of intensive land-use, and inputs of agro-industrial and municipal effluent. There is concern about the effects that inputs of nutrients and chemicals, which are largely uncharacterized, might have in the wetland, the river, and the downstream multi-use reservoir. Our project brings together partners from academic, industrial, and municipal sectors to generate novel information and data to guide water resource management, and answer pressing questions in watershed research regarding effluent fate, impacts, and the role of wetlands in effluent remediation. If well managed, aquatic habitats in the upper Little Bow River watershed will continue to provide decades-worth of ecosystem services in the coming years, which represents millions of dollars of services to stakeholders. Here, we will fill knowledge gaps to inform the management of this economically-important watershed. In turn this will help to maximize water treatment value to enhance other important ecosystem services in southern Alberta and throughout Canada. This research project serves as an important and cutting-edge model for similar effluent-receiving watersheds worldwide.

化学复杂的市政和工业废水释放到水生环境中是一个全球规模的问题，随着人口增长和增加的水量而迅速增加。废水释放对水生生态系统产生了复杂且定义不足的影响，并有可能对公共卫生产生负面影响。为了解决这些不确定性，我们设计了一项多学科研究计划，该计划定义了对生态系统对复杂废水负荷的生态学反应，该反应在艾伯塔省南部的社会经济上重要的流域中。像许多废水接收分水岭一样，上小弓河流域的弗兰克湖湿地也代表了一种复杂的管理场景。像其他流域一样，由于其悠久的土地利用历史以及农业工业和市政废水的投入，该系统面临着栖息地和水质的退化。人们担心在湿地，河流和下游多用途储层中可能存在很大程度上没有特色的营养和化学物质的投入。我们的项目汇集了学术，工业和市政部门的合作伙伴，以生成新颖的信息和数据来指导水资源管理，并回答有关流域研究中有关废水命运，影响以及湿地在废水补救中的作用的紧迫问题。如果管理良好的小弓河流域中的水生栖息地将在未来几年继续提供数十年的生态系统服务，这代表了为利益相关者提供数百万美元的服务。在这里，我们将填补知识空白，以告知管理这个经济重要的分水岭。反过来，这将有助于最大程度地提高水处理价值，从而增强艾伯塔省南部和整个加拿大的其他重要生态系统服务。该研究项目是全球类似的废水收集流域的重要尖端模型。
