  • Blanchard River Watershed TMDL Report
    State of Ohio Environmental Protection Agency July 2009 Blanchard River Watershed TMDL Report What are the essential facts? Ohio EPA studied the Blanchard River watershed and found water quality problems at all of the locations measured. The watershed can make progress towards restoration with practical, economical actions. Improving the streams depends on the participation of the watershed’s residents. What is the significance of this report? The Blanchard River Watershed TMDL Report is a tool that will include local ideas from the endorsed watershed action plan to help improve and maintain water quality and habitat in the watershed. What is a watershed? A watershed is the land area from which surface runoff drains into a specific body of water. Where is the Blanchard River and types of fish and aquatic collected in 2005 and 2006 to watershed? insects in the water.

  • Western Lake Erie Basin Collaborative Agreement
    State of Ohio’s Western Lake Erie Basin Collaborative Implementation Framework A Pathway for Transitioning Ohio to a Great Lakes Water Quality Agreement Domestic Action Plan February 2017 State of Ohio Western Lake Erie Basin Collaborative Implementation Framework Introduction On June 13, 2015, the governors of Ohio and Michigan, and the premier of Ontario committed to a goal of reducing phosphorus loadings to Lake Erie by 40 percent as specified in the Western Basin of Lake Erie Collaborative Agreement (Collaborative). The Collaborative is intended to advance efforts toward the proposed nutrient reduction targets put forth in the Great Lakes Water Quality Agreement (GLWQA). This will be done through the development of this Implementation Framework (Framework), ahead of the formal timeline for completing a state Domestic Action Plan (DAP) as set forth in the GLWQA. The Collaborative will focus on the western basin watersheds of the Maumee, Portage and Toussaint rivers and the Sandusky River. The GLWQA through the Domestic Action Plan will include the Central Basin tributaries of the Huron and Cuyahoga rivers, but these will not be addressed in detail in this Framework. Goals of the Collaborative • Achieve a 40 percent total load reduction in the amount of total and dissolved reactive phosphorus entering Lake Erie’s western basin by the year 2025 with an aspirational goal of a 20 percent reduction by 20201. • To use 2008 as the base year from which progress will be measured. • That each state and Province commits to developing, in collaboration with stakeholder groups, a framework outlining actions and timelines toward achieving the goals.

  • Blanchard River Watershed Model, OH Great Lakes Tributary Model Program (Section 516E, WRDA 96)
    Blanchard River Watershed Model, OH Great Lakes Tributary Model Program (Section 516e, WRDA 96) Project Location: This project is located in the Blanchard River watershed, which is located in the Counties of Allen, Hancock, Hardin, Putnam, Seneca and Wyandot in the State of Ohio. The Blanchard River is a tributary of the Auglaize River, which drains into the Maumee River and eventually into Lake Erie near Toledo, OH. Sediments and non-point pollutants from this watershed discharge to the Toledo Harbor and the Western Lake Erie basin. Project Description: Land use in the 771 square mile Blanchard Watershed is estimated to be 80.8% cultivated crops, 10.1% developed, 5.6% forest, 2.6% pasture and grassland, and < 1% open water and wetlands. This modeling effort will support local stakeholders in identifying sources of sedimentation and excess nutrients throughout the watershed. For this project, the Agricultural Non-Point Source (AGNPS) suite of models were applied to determine sediment sources, contributing locations, and the effect of best management practices (BMPs) on rates of sediment delivery to the mouth of the watershed. Project Benefits: The Blanchard River watershed model will: 1) Simulate erosion, sediment delivery pathways and sediment delivery yields and loads in the watershed; 2) Simulate fate and transport of nutrients throughout the watershed; 3) Project the potential benefits of conservation treatment strategies and best management practices and; 4) Support the larger GLRI effort by reducing erosion in the Maumee Basin and reduce sediment and associated nutrient delivery to Toledo Harbor and Lake Erie. Status: This two-year modeling effort will be completed in September 2010.

  • Using Water Quality Trading to Promote Conservation Measure
    USING WATER QUALITY TRADING TO PROMOTE CONSERVATION MEASURE ADOPTION IN THE BLANCHARD RIVER WATERSHED, OHIO, IN THE CONTEXT OF CLIMATE CHANGE DISSERTATION Presented in Partial Fulfillment of the Requirements for the Doctor of Philosophy in the Graduate School of The Ohio State University By Yanting Guo, M.Sc. Environmental Science Graduate Program The Ohio State University 2018 Dissertation Committee: Dr. Richard Moore Dr. Karen Mancl Dr. Charles Goebel Dr. Eric Toman Copyrighted by Yanting Guo 2018 ABSTRACT Agricultural phosphorus loading has been identified as the main cause of Lake Erie eutrophication and Harmful Algae Blooms since the mid-1990s. Efforts for alleviating the problem have been focused on promoting the adoption of conservation measures, such as the best management practices (BMPs). Water quality trading (WQT), a market-based mechanism that allows one pollution source (e.g. a factory) to meet their regulatory obligations by using pollutant reductions created by another source, such as agriculture, is a method to promote conservation through the lower pollution remediation costs of that source. Agriculture has a vast potential for supplying low cost conservation, however, limited studies have been done on farmers’ opinions about WQT or their selection and adoption of conservation measures in WQT programs. This study aims to fill this knowledge gap. The general objective of this study is to evaluate whether WQT has the potential to serve as an incentive to promote water quality conservation measures in the Western Lake Erie

  • Blanchard River Watershed Summary
    BLANCHARD RIVER WATERSHED SUMMARY The Blanchard River watershed is located in northwest Ohio in portions of Allen, Hancock, Hardin, Putnam, Seneca and Wyandot counties. The Soil and Water Assessment Tool (SWAT) was used to estimate this watershed’s contribution to nutrient loadings to the Western Basin of Lake Erie (WLEB), as well as simulate estimated nutrient outputs when specific best management practices (BMPs) were implemented. Model results estimated that ~30% of the Blanchard watershed contributes phosphorus outputs that range from 1.71 to 2.97 lbs/acre to the Blanchard River on an annual basis. The Blanchard River SWAT model was used to simulate phosphorus outputs if several agricultural BMPs were adopted at a rate of 50% in the areas that have higher Total P contributions. The scenarios modeled were: 1) subsurface application of fertilizer, 2) no-till practices, 3) P-fertilizer application at half the Baseline scenario rate, and 4) a combination of subsurface application of fertilizer, half P-rate application, no-till practices, and use of cover crops. Analysis of these scenarios shows: No single BMP provides optimal nutrient reduction everywhere. Not every BMP is best-suited for an area, or as a stand-alone BMP. Implementation of some BMPs help nutrient loads reach the Great Lakes Water Quality Agreement 40% reduction goal in some Hydrologic Unit Code (HUC-12) subwatersheds, while even a combination of BMPs is not enough to reach that goal in others. For those areas where nutrient reduction goals are not met, an adoption rate of greater than 50% or alternative BMPs may be needed.
