Purpose and Authority: This project entails a multi-purpose/ multi-objective evaluation of the Western Lake Erie Basin (WLEB) and Watersheds by the U.S. Army Corps of Engineers (USACE) to 1) integrate existing projects, plans and studies; 2) assess program progress; and 3) plan future lake and watershed revitalization programs and projects from various federal, state, local and non-governmental organizations. The final product, a comprehensive Western Lake Erie Basin and Watershed Framework, will provide public agencies, watershed groups and other stakeholders with a tool to facilitate the restoration, protection and sustainable use of the water and related natural resources within the study area. The WLEB study is authorized in Section 441 of the Water Resources Development Act (WRDA) of 1999. This authority directs the Assistant Figure E -1 – Location of the St. Marys River Watershed Secretary of the Army for Civil (Ohio DNR) Works to conduct a study to develop measures to improve flood control, navigation, water quality, recreation, and fish and wildlife habitat in a comprehensive manner in the WLEB. Figure E-1. Location of the Upper Maumee Watershed. (NRCS) 1 Upper Maumee Watershed Watershed Assessment August 3, 2009 Methodology: The preparation of the assessment consisted of 1) a comprehensive review of existing studies and technical reports to identify problems, opportunities, and project needs; 2) hosting a workshop at a central location in the watershed where elected officials, agencies, and citizens were invited to share their comments and identify local problems, needs and project opportunities; 3) distribution of a project needs request form to all county, community, state and local agencies and other nonprofit organizations by letter and also posting the request on the Figure E-2. Upper Maumee River. WLEB web site; 4) making direct contact with key agencies to request information on current projects and project needs; 5) distribution of draft materials to WLEB Partnership for review and comment; and 6) completion of both internal and external USACE Independent Technical Reviews (ITR). Watershed Characteristics: Physical System and Natural Resources : The Maumee River is formed by the confluence of the St. Joseph and St. Mary’s rivers at Fort Wayne, Indiana. The river flows in a northeasterly direction primarily through an agricultural region for about 130 miles where it empties into Lake Erie at Toledo, Ohio. Located in Allen and DeKalb Counties of northeast Indiana and Paulding and Defiance Counties of northwest Ohio, the Upper Maumee Watershed extends along the Maumee River from Fort Wayne, Indiana to Defiance, Ohio. The total estimated area of the Upper Maumee Watershed covers 125,964 acres in Indiana and 121,791 acres in Ohio. (Figure E-2). Socio-economic Characteristics : Most of the watershed is rural, with 494 Indiana farms in the watershed, covering approximately 88,129 acres; and 407 Ohio farms covering approximately 111,873 acres. The average size farm is 180 acres in Indiana and 275 acres in Ohio. Primary crops include corn, soybeans, wheat, confined livestock (hogs) and some beef cattle. Cultural Attributes : Native Americans arrived in the Maumee Valley about 12,000 years ago and, since that time the valley has been a corridor of commerce and transportation. By the 1700’s, several tribes had settled along the Maumee River; the Shawnee and Delaware at the confluence of the Auglaize and Maumee Rivers, and the Miami in what is now Lakeside Park in Fort Wayne. Institutional and Regulatory Setting: Most land use is managed by rural zoning via county and township governments. Given the dominance of agriculture in the watershed, in-stream water quality problems are generally related to agricultural land use practices and channel disturbance. Consequently, most of the area is subject to nonpoint pollution controls. 2 Upper Maumee Watershed Watershed Assessment August 3, 2009 Resource Analysis: Issues and Opportunities : Flood Risk Management : Significant flood risks exist due to the relative flatness and altered characteristics of the watershed, particularly in City of Fort Wayne. The confluence of the Upper Maumee and St. Mary’s in Fort Wayne, coupled with rapid runoff due to impervious surfaces common to urban land use, contributes to flooding problems. There is an opportunity to Figure E-3. Upper Maumee River. investigate additional flood reduction measures within the watershed, such as removing structures from the floodplain, creating flood water impoundments, and restoring or establishing wetlands to retain water for percolation and as a source of groundwater recharge. Water Quality : Impairments identified within the Upper Maumee Watershed include PCBs, E. coli, mercury, nutrients, flow alteration, un-ionized ammonia, impaired biotic communities, algae, total toxics and turbidity. These impairments impact negatively the overall health of the watershed and the health of the flora and fauna – including humans - that depend on the watershed. Opportunities exist to mitigate for some of these impairments (e.g., dredging to remove PCBs, developing riparian buffer strips to enhance streamside habitat while filtering runoff of sediments and nutrients.) Technical or cost factors make other impairments (e.g., airborne deposition of mercury, sediment deposited by wind erosion) more difficult to address. Natural Resource-based Recreation: Fishing opportunities are limited, as are other natural resource-based recreation opportunities, due to dominance of agricultural land use. Fish and Wildlife Habitat : Habitat for most wildlife is restricted to fence rows and occasional woodlots along streams and ditches in the area. Fish, species composition has changed significantly since the mid- 19 th century. Drainage of the Black Swamp resulted in declines of commercially important fish including muskellunge ( Esox masquinongy) , northern pike ( Esox lucius) , lake sturgeon ( Acipenser fulvescens), walleye ( Stizostedoin vitreum ), smallmouth bass ( Micropterus dolomieui ) and several species of sucker. These once abundant species have now disappeared or suffer greatly reduced numbers. Their decline has coincided with an increase in less desirable species such as quillback carpsucker ( Carpiodes cyprinus ), gizzard shad ( Dorosoma cepedianum ), freshwater drum ( Aplodinotus grunniens ), buffalo ( Ictiobus spp .) and the introduced carp ( Cyprinus carpio ) Commercial and Recreational Navigation: The Upper Maumee does not support commercial navigation. Recreational navigation, such as canoeing or shallow draft 3 Upper Maumee Watershed Watershed Assessment August 3, 2009 fishing, is associated with upland reservoirs, ponds or small lakes, and seasonally along 1st and 2 nd order streams. Findings and Potential Actions: Due to significant changes associated with the permanent alteration of the watershed, the WLEB has lost most of its natural ecosystem features. Also, urbanization and encroachment into natural floodplains has made flooding problems commonplace. This is particularly true within the City of Fort Wayne, which has experienced extensive and frequent flood damage since the area was settled. Overall, water quality ranges from good in the lower portions of the WLEB to poor in the upper areas where extensive siltation and urban runoff is occurring. Selected potential actions are summarized below, a complete list is found in Appendix E. UPPER MAUMEE RIVER WATERSHED PRIORITY POTENTIAL ACTIONS SUMMARY Flood Risk Management, Water Supply, Sediment and Erosion Reduction Acquire all residential structures in floodplain.

    2000 Lake Erie Lamp

    Lake Erie LaMP 2000 L A K E E R I E L a M P 2 0 0 0 Preface One of the most significant environmental agreements in the history of the Great Lakes took place with the signing of the Great Lakes Water Quality Agreement of 1978 (GLWQA), between the United States and Canada. This historic agreement committed the U.S. and Canada (the Parties) to address the water quality issues of the Great Lakes in a coordinated, joint fashion. The purpose of the GLWQA is to “restore and maintain the chemical, physical, and biological integrity of the waters of the Great Lakes Basin Ecosystem.” In the revised GLWQA of 1978, as amended by Protocol signed November 18, 1987, the Parties agreed to develop and implement, in consultation with State and Provincial Governments, Lakewide Management Plans (LaMPs) for lake waters and Remedial Action Plans (RAPs) for Areas of Concern (AOCs). The LaMPs are intended to identify critical pollutants that impair beneficial uses and to develop strategies, recommendations and policy options to restore these beneficial uses. Moreover, the Specific Objectives Supplement to Annex 1 of the GLWQA requires the development of ecosystem objectives for the lakes as the state of knowledge permits. Annex 2 further indicates that the RAPs and LaMPS “shall embody a systematic and comprehensive ecosystem approach to restoring and protecting beneficial uses...they are to serve as an important step toward virtual elimination of persistent toxic substances...” The Great Lakes Water Quality Agreement specifies that the LaMPs are to be completed in four stages. These stages are: 1) when problem definition has been completed; 2) when the schedule of load reductions has been determined; 3) when P r e f a c e remedial measures are selected; and 4) when monitoring indicates that the contribution of i the critical pollutants to impairment of beneficial uses has been eliminated.

    The Maumee River Watershed and Algal Blooms in Lake Erie1 2

    SESYNC Case Study The Maumee River Watershed and Algal Blooms in Lake Erie1 2 Ramiro Berardo3 & Ajay Singh4. Summary: The decay of Lake Erie’s environmental health and its impacts on local communities, including public health and the environment, was one of the focal events motivating the passage of the Clean Water Act in 1972. Despite the considerable improvement in water quality in the 1970s and 1980s because of implementation of agricultural best management practices to address soil erosion, seasonal algal blooms returned to Western Lake Erie. Potential causes of algal blooms may be a mixture of agricultural and urban practices that threaten ecological stability and public health for millions dependent on the lake for drinking water, tourism, and fisheries. For instance, in fall, 2014, national attention turned to the city of Toledo, Ohio as the city’s residents experienced disruption to city services such as access to potable water and certain medical services including child birth and surgery. For this case study we will study the relationship between human behavior and water quality impairments which lead to toxic algal blooms in the Western Lake Erie Basin, and in particular, the Maumee River Watershed. We will also review prior management and policy efforts of different stakeholders to improve water quality as well as issues surrounding the development of proposed policy and management changes. Multiple stakeholders from multiple states and Canadian provinces are involved in seeking solutions to the ongoing pollution problems. This case study will be ideal to examine how cooperation unfolds in the presence of collective action problems, and the interrelationships between human behavior and environmental outcomes.

    Movements and Spawning of Bigheaded Carps in the Upper Wabash River, Indiana, USA: 2013 Update

    Movements and Spawning of Bigheaded Carps in the Upper Wabash River, Indiana, USA: 2013 Update Alison Coulter1, Graduate Research Assistant [email protected] Reuben R. Goforth, Ph.D.1, Principal Investigator [email protected] 1Department of Forestry and Natural Resources, Purdue University, 195 Marstellar Street, West Lafayette, IN 47907 Introduction Over 180 aquatic non-indigenous species (NIS) have been introduced into Great Lakes Basin waters to date, and new introductions are expected in the future. The so-called “bigheaded carps” (e.g., silver Hypophthalmichthys molitrix and bighead H. nobilis) are considerable threats to the Great Lakes given expected trajectories of nutrient flow disruption and food web alterations that will likely accompany their introduction to the Basin. While great effort has been expended to keep these species from entering the Great Lakes Basin via the Illinois River and its connection to the Chicago Sanitary and Ship Canal, an additional pathway for introduction has been identified at Eagle Marsh near Fort Wayne, Indiana. Eagle Marsh may provide a corridor for movement of these species between the Wabash and Maumee River basins during high water periods. The direct connection of the Maumee River with Lake Erie would therefore provide a means for introduction of bigheaded carp to the Great Lakes. Immediate action has been taken to prevent such an introduction through the installation of a physical barrier across Eagle Marsh. However, the potential ranges and rates of movement by silver and bighead carps throughout the Wabash River, and especially into the Little River and Eagle Marsh, are not fully understood. Understanding the movements of invading species in novel environments is important for predicting potential impacts (DeGrandchamp et al.

    The Fresh-Water Naiades of Auglaize County, Ohio

    THE FRESH-WATER NAIADES OF AUGLAIZE COUNTY, OHIO CLARENCE F. CLARK, Ohio Division of Conservation and Natural Resources, St. Marys, Ohio This paper deals with 30 collections of mussels taken at 24 stations (Fig. 1) in the drainage systems of Auglaize County during the past four years, 1938-42. The materials are of interest because: (1) no other naiad records have been pub- lished for this area; (2) rapid changes in stream ecology necessarily alter the mussel fauna; and (3) the proximity of headwater streams of the Ohio and Lake Erie drainages produce interesting distribution patterns for comparison. In the general vicinity, Goodrich (1914) reported on naiades from the Wabash River in Mercer County; Clark and Wilson (1912) surveyed the Maumee and Auglaize Rivers of Defiance County; Kirsch (1894) investigated the Maumee Basin; Ortmann (1919) reported on mussels from the St. Marys River, Beaver Creek, and Lake St. Marys in Mercer County, the Maumee River in Defiance County, the Scioto River in Hardin County, and Indian Lake in Logan County. These collections have been made in counties to the west, north and east of the region considered at present. Records of Sterki (1907) and those from the Carnegie Museum of Pitts- burgh list specimens from the Great Miami drainage to the south.
