Nick Proulx, MN DNR
The City of Rochester is located in SE Minnesota along the banks of the Zumbro River. During the 1970’s – 1980’s, the City undertook a massive effort to manage flood waters primarily by building dams on tributaries that flow into the Zumbro. In the early 2000’s, several studies were funded to find ways of addressing hydrology in Cascade Creek by holding back water on the landscape. Recommendations from the studies included the downsizing of culverts and/or placing weirs just above road crossings to temporarily hold water during spring run-off and large rain events. After negotiations it was agreed, the DNR would permit up to two structures to be placed on-channel, Olmsted County would continue perennial buffer compliance work and the DNR would complete a stream restoration, and compare the results. The group would work together to secure funding for the projects and support monitoring efforts to compare these two approaches.
In this presentation, the objectives and monitoring effort using the 5 component framework will be outlined. In addition, channel design strategy and associated metrics for the stream restoration will be covered as well as a comparison of a stream project downstream. Final thoughts on how using NCD principals helped addressed stakeholder’s expectations, how the 5 components expanded the scope and scale of the project and lessons learned.
