Streambank Stabilization Projects

Before Construction Streambank stabilization has been a key component in the reduction of sediment entering our water supply reservoirs. The coordination between the Kansas Department of Health and Environment (KDHE) (Watershed Management Section), the Kansas Department of Agriculture (KDA) (Division of Conservation), and the Kansas Water Office (KWO) have utilized the strengths, responsibilities, and resources of each agency to accomplish streambank protection work. In order to complete projects in the most efficient and cost effective manner, the inter-agency team operates from a pooled funding system. Funds available through agency programs for streambank protection projects are targeted to priority areas and administered by this group. The Kansas Forest Service (KFS), Kansas Department of Wildlife, Parks, and Tourism (KDWPT), local conservation districts (CD), and local Watershed Restoration and Protection Strategy (WRAPS) groups continue to be essential to the success of this process.

Streambank stabilization efforts are currently being concentrated in three high priority watersheds, the Big Blue and Little Blue Rivers above Tuttle Creek Lake, the Delaware River above Perry Lake, and the Cottonwood and Neosho Rivers above John Redmond Reservoir. Past efforts have included implementation projects across the state, including within the Smoky Hill-Saline watershed. It is estimated the streambank stabilization projects implemented to date will prevent just over 880,000 tons of sediment from entering the associated downstream reservoirs each year.

Funding

In order to complete projects in the most efficient and cost effective manner, the group has adopted a “pooled funding” concept. Funds available through agency programs for streambank stabilization projects are targeted to priority areas and administered by this group. The KFS, KDWPT, local conservation districts, and local WRAPS groups are also important to the success of this process.
