1022-013 Dry Run Creek Watershed Final Report

The Dry Run Creek Watershed received a biological impairment in 2002 after sampling conducted by the Department of Natural Resources revealed a lack in the diversity and abundance of aquatic life along a 2.8 mile reach of stream along the Southwest Branch. Among the primary stressors identified were hydrologic change, increased stormsewer inputs, lack of available habitat, and sedimentation. Goals put forth by the Watershed Management Plan and the preliminary Total Maximum Daily Load (TMDL) study center around the reduction in storm sewer inputs. The goal set forth by the TMDL is the reduction of connected impervious surface (CIS) to 10% in each of the creek’s subwatersheds as a surrogate for other stressors. Grant funding is being sought for the construction of two bioretention cells and a green roof to treat the first flush of runoff from a new 400 unit student housing structure and connected parking surfaces totaling 5.16 acres. In addition, a monitoring program will continue to be coordinated through a partnership with the Department of Natural Resources IOWATER program and locally led volunteer efforts which will allow us to track the progress of the watershed. Funding for administration, outreach, and assessment will be provided through existing 319 grants. Implementation of these practices will occur in phases over the course of a two year period.

05046-017 Dry Run Creek Watershed Final Report

Dry Run Creek Watershed was designated an impaired waterbody by DNR in 2002, following an assessment of the biota in the stream by DNR Biologist, Tom Wilton. Subsequent studies by IOWATER Snapshot effort in 2003, found e-coli bacteria concentrations and high nitrate readings in excess of the State of Iowa limits for recreational streams. The Dry Run Creek Watershed Improvement Project is comprised of five major components. Three components will feature demonstrations of structural best management practices (BMPs) to protect water quality in Dry Run Creek. The fourth is an educational workshop to "kick-off" the initiative and background the stakeholders of the watershed in new stormwater management strategies for water quality protection. The fifth is a monitoring program that will provide data on the effectiveness of the practices to be demonstrated. Measurable outcomes from these projects include monitoring to document the effectiveness of infiltration­ based BMPs to reduce pollutant loading in urban stormwater runoff and reducing the volume of stormwater discharged directly into Dry Run Creek via storm sewer flows. Understanding of and social acceptance of new stormwater strategies and practices will also be monitored by surveys of watershed stakeholders and compared to findings of a survey done before the start of the project.

09031-016 Duck Creek Watershed Final Report

The Duck Creek Watershed, the recipient of a 2009 DNR Watershed Management Planning Grant and a focus of an upcoming City of Davenport master plan, is characterized by relatively flat grades and highly impervious areas. Plagued by issues such as high bacteria loads, stream bank erosion and flooding, solving these problems may take generations. The City of Davenport has taken a microwatershed approach to identify the significant contributors to water quality and flooding issues that affect Duck Creek, its tributaries and the surrounding landscape to make inroads into the larger issues. This project is the next phase of a multi-phased project that addresses the microwatershed that includes St Ambrose University. Work here will improve water quality within Duck Creek and address major flooding issues on campus while also reducing downstream flooding. This project will convert an existing parking lot into a green parking area by removing the hard surface and installing below ground facilities for storm water infiltration, detention, and reuse. Permeable pavement, bio­ swales and infiltration areas will be constructed on top of the infiltration facilities. We estimate that this project will capture and treat 1,110,000 gallons (3.5 acre feet) of storm water runoff which accounts to the runoff volume from a 10-year storm event while reducing pollutants by 30-100%.

1241-018 Swan Lake Watershed Final Report

This project would construct a sediment basin on the main inlet stream to Swan Lake, an impaired waterbody currently on the 303(d) list. This project is one of the highest priorities in our Watershed Management Plan. According to STEPL modeling, it would sequester over 1/3 of the total phosphorus (the pollutant of main concern) coming into the lake.

1118-007 Lake Hendricks Watershed Final Report

Lake Hendricks is a 54 acre man-made lake that is encompassed by a 1,209 acre watershed. Lake Hendricks is currently on the 303(d) Impaired Waters List for algae and pH impairments due to an abundance of algae growth caused by nutrients being delivered to the lake via 11 separate tile lines draining adjoining cropland areas. In 2009, a Watershed Management Plan was developed in partnership with IDALS and the IDNR 319 programs and $256,500 was awarded to address the nutrient and sediment loading of the lake. Over the past three years a total of $251,000 were spent to implement one grade stabilization structure, two sediment basins, two bioreactors, 700 feet of streambank stabilization, 30.7 acres oftimber stand improvement, and 39.4 acres of Conservation Reserve Program (CRP). A proposed wetland structure and three sediment basins are scheduled to be constructed in the fall of 2011. Current water monitoring data is showing an average of 54% Nitrate (N) loading reductions as a result of the installed BMPs. The District feels further reductions are possible by addressing nutrient management issues in the cropland areas, stabilizing additional streambanks, and improving the surrounding woodland areas. The goal is to reduce N loading by an additional 20% and sediment loading by 50 tlac/yr. The resulting collaborative effort may lead to the future de-listing of Lake Hendricks from the 303(d) Impaired Waters List.

1228-013 Center Lake Watershed Final Report

A targeted approach is being used in the Iowa Great Lakes Watershed with a keystone project featured within this project application in the heavily urbanized Center Lake Watershed. As identified in the Iowa Great Lakes Watershed Management Plan, urban runoff is the only remaining watershed concern in the Center Lake Watershed as the map in the attachments clearly shows. Fully one third of the watershed concerns of Center Lake will be treated through the installation of 7 keystone urban practices and will remove 63 pounds of phosphorous from entering the lake annually. Due to the interconnectedness of the Iowa Great Lakes (IGL), the watershed has been broken down into sub units called Resource Management Areas (RMA's) for priority practice implementation. This project will mesh with the existing Iowa Great Lakes Watershed Management Plan by reducing pollutant loads from the highest priority RMA's which are resulting in impaired water bodies. The majority of the funding needed for the specific practices specified in this proposal has already been secured through the Iowa DNR Section 319 and Lake Restoration Programs, The Water Quality Commission and the City of Spirit Lake. This funding request will simply bring the overall cost of these keystone practices into the range of affordability for the committed funders and the City of Spirit Lake
