Southern Alberta Flood Mitigation Feasibility Study For Sheep Highwood River Basins And South Saskatchewan River Sub Basin PDF Download

Expand and fully balance Chin Reservoir in the Oldman sub-basin to optimize the usefulness of an existing reservoir for providing irrigation water and to alleviate storage demands in other upstream reservoirs, thus keeping more water closer to the headwaters and available to support ecosystems and human water uses throughout the system. [...] Build new on-stream storage high in the Southern Tributaries of the Oldman sub-basin, potentially the previously identified Kimball site, and balance this new reservoir with the other reservoirs in the Oldman sub-basin to reduce water shortages for irrigation and municipal users and improve the ability of all reservoirs to maintain environmental flows. [...] This project was not designed to explore the technologies and activities that contribute to demand management and reduction, but many of these are included in the water conservation, efficiency and productivity plans prepared for the seven major water-using sectors,4 which is the first listed strategy in the Adaptation Roadmap. [...] It was also recognized that the trade-offs needed to properly identify and evaluate the strategies were partially represented in the models and well-represented in the expertise and experience of working group participants. [...] In much of the basin, water management has focused on drought mitigation, but the floods of 1995, 2005, and 2013 reminded everyone of the diverse hydrological conditions experienced in the region-and of the need to be resilient and adaptable in responding to a wide range of future climate events and impacts.
