Nose Creek Watershed Water Management Plan completes round of engagement on final draft

Posted on May 22, 2018 in Guidance Documents , Volume Targets, Stream Stability, Water Quality, Riparian Setbacks

Nose Creek was the first watershed in Alberta to implement a runoff volume control target. The updated plan calls for the target to be held at the 2013 level pending additional modelling and monitoring work and introduction of provincial reuse policy, guidelines, and performance criteria. In addition, the plan calls for a redevelopment runoff volume control target and related water quality objectives to be established, and to improve certainty and timeliness of approvals incorporating LID. The plan also addresses riparian setbacks and water quality. Comments are being accepted until June 15, 2018.
