09006-003 Bear Creek Watershed Final Report

Bear Creek is an impaired warm water fishery designated as class B(LR) by the Iowa DNR and is on 303 impaired waters list for fish kills and ammonia. Bear Creek is located in eastern Delaware County. This project is designed to improve the water quality of Bear Creek by educating the landowners, operators and watershed community about the importance of this water resource. The goal of the Bear Creek Watershed Project is to improve the water quality of Bear Creek by reducing the amounts of ammoniated manure discharge, fecal coliform bacteria, sediment, nitrogen, and phosphorous. The Bear Creek Watershed Project has been a watershed project since July 2004, first as a Demo project FY 2004-2005 and then full time WSPF/319 project FY06-09. Fish kills have not occurred in 2008-2009. Sediment delivery has decreased in the Bear Creek Watershed by 5,328 tons per year. The objectives of this watershed project will be to improve Livestock Waste Storage, to improve Livestock Waste Usage, to decrease Sediment Losses, and to improve Education & Area Outreach. This project will install 2 manure storage structures (EQIP/project funded), 19 ac of CRP waterways, 12 ac of project waterways, 17 ac of CRP filter strips along stream, 12 water and sediment control basins, 18,000 ft of terraces, 350 ac of new notill planting, and 3,700 ft of streambank protection.

1010-005 Bloody Run Creek Watershed Final Report

The City of Marquette lies in the 65,000 acre Mississippi River watershed, and is surrounded by steep bluffs. Though scenic, controlling water runoff during storm events presents significant challenges. Flash-flooding from the local watershed has plagued the city for decades. The people of Marquette have committed to preserve the water quality of key natural resources in the area including the Bloody Run Creek and associated wetlands by undertaking projects to control the spread of debris and sediment caused by excess runoff during area storm events. Following a July 2007 storm (over 8” of rain in 24 hours) which caused unprecedented flood damage, the City retained an engineering firm to study the area and provide recommendations to eliminate or greatly reduce uncontrolled runoff into the Bloody Run Creek wetland, infrastructure damage and personal property loss. Marquette has received Iowa Great Places designation, and has demonstrated its commitment to wetland preservation with the construction of Phase I of this water quality project. The Bench Area Storm Water Management Plan prepared by the City in 2008 made a number of recommendations to mitigate flash flooding by improving storm water conveyance paths, detention, and infrastructure within the Bench area. Due to steep slopes and rocky geography, infiltration based systems, though desirable, would not be an option over surface based systems. Runoff from the 240 acre watershed comes primarily from large, steep drainage areas to the south and west, flowing to the Bench area down three hillside routes; designated as South East, South Central and South West. Completion of Phase I, which included an increased storage capacity of the upper pond, addressed the South East and South Central areas. The increased upper pond capacity will now allow Phase II to proceed. Phase II will address runoff from the South West drainage area; which engineers have estimated to produce as much water volume as the South Central and South East areas combined. Total costs for Phase I are $1.45 million, of which Marquette has invested $775,000, and IJOBS funding contributed $677,000. Phase II costs are estimated at $617,000. WIRB funding support of $200,000 would expedite project completion, lessen the long term debt impact to the community and aid in the preservation of the Bloody Run Creek and adjoining wetlands more quickly than Marquette could accomplish on its own.

Health consultation : Rolfe aboveground storage tank petroleum bulk plant targeted brownfields assessment, Railroad Street and 300th Avenue, Rolfe, Pocahontas County, Iowa (2005)

The Iowa Department of Natural Resources (IDNR) has requested the Iowa Department of Public Health (IDPH) Hazardous Waste Site Health Assessment Program evaluate future health impacts of exposures at a former aboveground storage tank site located in Rolfe, Iowa. The former aboveground storage tank site is located to the southwest of the intersection of Railroad Street and 300th Avenue in Rolfe, Iowa. This site is undergoing a Targeted Brownfields Assessment conducted by the Contaminated Sites Section of the IDNR. This health consultation addresses potential health risks to people from future exposure to the soil within the property boundary, and any health impacts resulting from contaminated groundwater beneath the site property. The information in this health consultation was current at the time of writing. Data that emerges later could alter this document’s conclusions and recommendations.
