Stream and Riparian Restoration in the Lower Smoky Hill River Basin

The Kansas Water Office has received funding from the Kansas Water Pollution Control Revolving Fund (KWPCRF) to address sedimentation in the Lower Smoky Hill River Basin. A total of approximately one mile streambank above the City of Salina intake on the Smoky Hill River has been identified as a high priority area for streambank stabilization to reduce sedimentation by about 5,475 tons. Restoration of the riparian buffer adjacent to the stream is also a goal of this project.

During the summer of 2012 the Survey and Design work will be conducted for this project. The Watershed Institute (TWI) of Kansas will conduct the survey and design work.  Draft designs will be presented to landowners by the fall of 2012.

In the fall 2012, the Kansas Water Office will issue an Invitation for Bid (IFB) for the construlction of the Lower Smoky Hill Streambank Stabilization projects. The IFB and additional project information will be provided and updated on this website.

Each project survey and design will conform to NRCS Conservation Practice Standard 580, Streambank and Shoreline Protection; Conservation Practice Standard 322, Channel Bank Vegetation; and Conservation Practice Standard 484, Mulching which are in Section IV of the electronic Field Office Technical Guide (eFOTG). The designs will include documentation necessary to meet the applicable standards and statements of work which are also in the eFOTG. The construction specification, operation and maintenance (O&M) plans, and general notes included on the drawings shall be tailored to the individual project.

Lower Smoky Hill River Watershed - Salina Area

The City of Salina draws sixty to eighty percent of its drinking water from the Smoky Hill River. The main treatment issue for the river water prior to consumption is turbidity caused by excess soil particles in the water column. In addition, the excess sediment in the river can affect the surface diversion by requiring the removal of excess sediment at the water intake.

The Kansas Department of Health and Environment (KDHE) has identified impariment to ecosystem quality because of excessive sediment as a Total Maximum Daily Load (TMDL) for Total Suspended Solids (TSS) for the Lower Smoky Hill River from Kanopolis Reservoir to Salina. The streambank stabilization and riparian restoration projects will address the high priority TMDL approved by EPA in 2011.

The sites for this project were selected because they address the WRAPS sedimentation goal; builld even stronger partnerships between the City of Salina, the WRAPS SLT and other stakeholders; and serves a greater population than other higher priority sites. An assessment conducted by The Watershed Institute (TWI) for the Upper Lower Smoky Hill WRAPS Stakeholder Leadership Team (SLT), identified streambank erosion "hot spots" throughout the watershed. TWI ranked each of the sites identified based on the rate of erosion. The sites selected for this project were identified as having a significant rate of erosion.

Nonpoint Source (NPS) Project Management Plan

One of the requirements for obtaining the KWPCRF loan is the preparation and public review of a Nonpoint Source (NPS) Project Management Plan. A draft of the plan is provided here. If you have comments or questions reagarding the plan or project, contact Diane Coe, Kansas Water Office, at (785) 296-3185 or Diane.Coe@kwo.ks.gov.
