1240-017 Little Bear Creek Watershed Final Report

Little Bear Creek is a 21.79 mile Class A1 and B (WW2) warm water stream that encompasses approximately 29,202 acres in northern Poweshiek County. The lower 8.4 mile segment is listed as biologically impaired on both the IDNR 2008 303(d) list and 2010 303(d) draft list. A RASCAL assessment and landowner survey was completed through a development grant in 2011, and these assessments indicate that erosion and sediment delivery from cropland, lack of adequate buffers along the stream channel, and streambank conditions contribute significant sediment delivery to the stream, likely resulting in the impairment. An estimated 36,544 tons of sediment are delivered to the stream annually. A total of 11,075 acres (38%) of the watershed are high priority areas or land with sediment delivery rates greater than one. Our goal over 15 years is to install Best Management Practices (BMPs) and increase public education in order to reduce sediment and phosphorus delivery by 25% and decrease priority areas by 15%. More specific objectives for this WIRB project are to 1) Reduce annual sediment delivery by roughly 16.3% or 1,058 tons and associated phosphorus delivery by 1,375 pounds and 2) Develop an information and education program aimed at producers and residents within the headwaters of Grant and Chester townships, which account for 18% of the watershed's priority areas. The SWCD proposes to utilize 50% EQIP funds and 25% WIRB funds toward rural BMPs, and 75% WIRB funds toward urban BMPs received through this application.

Watershed Planning Advisory Council 2015 Annual Report, December 10, 2015

The Watershed Planning Advisory Council (WPAC) was established by the Iowa Legislature (see Appendix A: Iowa Code 466B.31) to assemble a diverse group of stakeholders to make recommendations to state and federal agencies to protect water resources in Iowa. In 2015, WPAC prioritized the seven areas for recommendations outlined in 466B.31, and small work groups drafted recommendations for approval by the full membership.

1209-006 Waterloo Creek Watershed Final Report

Waterloo Creek Watershed is a 30,610 acre area that straddles the Iowa and Minnesota border. The lower 43% of the watershed is in Iowa. Bee and Duck Creeks in Minnesota flow into Waterloo Creek in Iowa. Designated as a primary contact recreational stream as well as a high-quality, cold water stream in Iowa, Waterloo Creek is a popular destination for anglers and other nature enthusiasts. The stream was on the Iowa DNR’s “Impaired Waters List” in 2008 and 2010 for Escherichia coli (E. coli) bacteria. Samples collected in 2010 and 2011 showed higher levels of E. coli. at sites with cattle in close proximity to the stream and were generally greater after high rainfall events. Other factors affecting water quality are high turbidity levels and frequent flooding. There is a deficiency in upland land treatment and an abundance of conventional tillage which increases the amount of erosion and potential for surface runoff to carry sediment to the stream. A comprehensive watershed assessment and management plan have been completed for the watershed which identify the causes of and solutions to water quality impairments. The goals of this project are to 1) develop a formal working relationship between technical staff in Iowa and Minnesota, 2) identify specific locations for Best Management Practice (BMP) implementation, 3) reduce sediment loading to Waterloo Creek to improve aquatic habitat and decrease bacteria delivery, and 4) reduce flooding potential in the watershed. The following BMPs will be implemented to reach these goals: terraces, grade stabilization structures, pasture management, stream buffers, stream bank stabilization, and agricultural waste structures.

09014-010 Lytle Creek Watershed Final Report

Brief Project Summary (no greater than this space allows): Leisure Lake is a 20 acre water body located in northwest Jackson County with a 2,581 acre drainage area. This portion of the Maquoketa Watershed including the lake is a tributary to Lytle Creek which drains into the North Fork Maquoketa River and into the Maquoketa Watershed. Portions of the Lytle Creek and North Fork Maquoketa River are on the 303(d) impaired waterbodies list. The project area includes a community of 370 residential properties and one business that currently has no central waste water collection and treatment system. The County Sanitarian estimates at least 225 of these properties do not have properly operating septic systems and ultimately drain their wastewater into the lake. The purpose of this project is to construct a wastewater collection and treatment facility to improve water quality in the creek and river. The project will eliminate the non-permitted septic systems and construct a new wastewater system to properly treat wastewater prior to its discharge into the waterways.

Rathbun Lake Special Project: BMPs for priority land in Targeted Sub-Watershed 2012 1221-010, Final Report 2013-2061,

The Rathbun Land and Water Alliance and partners have undertaken a highly effective approach to water quality protection through the Rathbun Lake Special Project. This approach is achieving a significant reduction in the sediment and phosphorus that impair water quality in Rathbun Lake and its tributaries as a result of the targeted application of best management practices (BMPs) for priority land in the watershed. This project application proposes to assist landowners to apply BMPs that will reduce sediment and phosphorus delivery from priority land in three targeted sub-watersheds as part of the Rathbun Lake Special Project. Features of this project are: (1) use of geographic information system (GIS) analysis to identify priority land that requires BMPs; (2) assistance for landowners to apply BMPs for 1,200 acres that will reduce the annual delivery of sediment by 1,800 tons and phosphorus by 6,000 pounds; (3) evaluation of the benefits from BMP application using GIS analysis and water quality monitoring; and (4) watershed outreach activities that encourage landowners to apply BMPs for priority land to protect water quality.

Dry Run Creek Watershed Improvement Project 1248-023: Final Project Report: July 2013-December 2015, October 11, 2016

In 2010 a group of farmers in the Dry Run Creek watershed, an Iowa High Quality Water Resource, formed the Dry Run Creek Watershed Improvement Association to learn more about and implement solutions to remedy a bacteria impairment in their stream. Through a partnership with Luther College, Iowa DNR Watershed Monitoring and Assessment and Iowa State University Extension the farmers were able to conduct an assessment of their stream and watershed. The assessment showed multiple potential sources of bacteria, dependent on whether water samples were collected following rain events or during dry conditions. This project will allow watershed farmers to implement solutions to reduce bacteria delivery during both wet and dry weather. Funding will be targeted to feedlot runoff control improvements, cover crops and vegetative filters, manure management strategies and livestock stream access. The council intends to continue intensive water monitoring to determine whether the strategies are successful. Research shows the bacteria reduction in water bodies can be seen relatively quickly, within 1-2 years, compared to other types of impairments.

Lake LaVerne Watershed Project Progress Report: Project Number 1415-007, Final Report, June 30, 2016

This application targets a critical need for low maintenance and inexpensive treatment solutions to encourage landowners and resource managers to enhance the water quality of small ponds and lakes. Many rural and urban small ponds and lakes across Iowa and the region have eutrophic conditions with high levels of nutrients and low levels of oxygen. Story SWCD teamed with Iowa State University (ISU) researchers propose to address this need through the construction and monitoring of a vegetated floating island (VFI) system on ISU's iconic Lake LaVerne. VFI's are hydroponically-vegetated islands that reduce nutrient loading directly from pond and lake water (rather than from soil adjacent to the pond). Urban watershed assessment on the ISU campus has already led to reductions in stormwater runoff to the lake but eutrophic conditions persist and are well documented. The VFI will function as a public art attraction for the entire 2015 growing season during which time monitoring will occur to quantify nitrogen, phosphorus and carbon changes in the lake. Tens of thousands of visitors to the ISU campus and Lake LaVerne will interact with this installation using promotional signage on site, public events and interactive social media throughout the project. Water quality and vegetation analysis will quantify nutrient uptake by the island vegetation and thus determine its effectiveness for use in other similar water bodies in Iowa.

Building Jobs in Iowa: New Deal Dams of the Wapsipinicon River Watershed in Northeast Iowa, February 4, 2015

The Wapsipinicon River, affectionately known as the “Wapsi,” flows nearly 300 miles through northeastern Iowa to the Mississippi. Strung throughout its drainage basin is a series of dams that are highly valued by their communities as places of recreation and scenic beauty. The Wapsipinicon has long had a reputation as a fishing stream, known for catfish, northern pike, carp, sunfish, walleye, and smallmouth bass. It is not uncommon to find anglers of all ages gathered at one of the Wapsipinicon’s dams to enjoy a day of fishing and possibly take home a prize catch. As time passes, however, a dam may outlive its original function, impede fish passage, and pose a safety hazard. But the idea of demolishing an outdated dam often rallies the community in an attempt to preserve the landmark.
