Unique Wetland Restoration Considerations in the Maumee River and Bay UNIQUE WETLAND RESTORATION CONSIDERATIONS IN THE MAUMEE RIVER AND BAY Phil Hicks, P.E., Hull & Associates, Inc. Cassie Lovall, ERT Contractor, NOAA Restoration Center Ohio Stormwater Conference Kalahari Resort & Conference Center, Sandusky, Ohio May 12, 2017 Sandusky LOWER MAUMEE RIVER AND BAY CONDITIONS Hosts largest fish spawning migrations of any Great Lakes tributary Lower Maumee River and Maumee Bay has filled and hardened shoreline . Floodplain wetland habitat is almost non-existent . Essential for healthy fish communities and wildlife Maumee River Beneficial Use Impairments (BUIs) include BUI 3: Degradation of Fish and Wildlife Populations and BUI 14: Loss of Fish and Wildlife Habitat This area absolutely needs more wetlands . Fish nursery habitat is a special need CITY OF TOLEDO’S PENN 7 FORMER CONFINED DISPOSAL FACILITY RESTORATION PENN 7 RESTORATION OPPORTUNITY Former confined disposal facility . Filled in 1972 – 1973 with approximately one million cubic yards of dredged material from the Toledo shipping channel . Berm surrounds perimeter . Heights range from 3 -12 feet . Creates a hydrologic barrier between the land and river . Interior area with hydric soils supports some wetland vegetation, but wetlands are isolated from the river, dry completely for at least a portion of the year, and have little value as wildlife habitat . Owned by City of Toledo NOAA GREAT LAKES RESTORATION INITIATIVE GRANT City of Toledo sought and received a $175,000 NOAA GLRI grant in 2015 . Site characterization activities and feasibility study to determine the restoration potential of creating emergent coastal/floodplain wetland habitat at Penn 7 . City of Toledo hired the Hull Project Team (MBI, Stock Drilling, Garcia Surveyors, Pace Aalytical) to complete activities. Toledo-NOAA-Hull Project Team worked closely throughout 2015-2017 project period DATA COLLECTION/EVALUATION TASKS Task 1: Preparation of Quality Assurance Project Plan (QAPP) Task 2: Existing Data Acquisition and Site Reconnaissance Task 3: Site Characterization Task 4: Topographic Survey/Mapping Task 5: Surface Water/Ecological Evaluation Task 6: Hydrologic and Hydraulic Evaluation Work also included a conceptual grading plan and feasibility determination. NOTEWORTHY DATA COLLECTION/EVALUATION FINDINGS Some Chemicals of Concern are present in Penn 7 soils and sediments Analysis Findings . Penn 7 materials are no more impacted than surrounding Maumee River sediments . Restoration activities would not have a deleterious impact on the surrounding area, even if some Penn 7 materials are released or come in contact with the Maumee River . Future confirmatory sampling needs should be considered once the final design of the restoration area is complete NOTEWORTHY DATA COLLECTION/EVALUATION FINDINGS The presence, condition and numbers of types of biological habitat (fish, macros, etc.) were evaluated to determine the quality of existing conditions. Evaluation/Analysis Findings: . All three sampling sites near Penn 7 had low quality biological habitat for Lake Erie lacustuary criteria. Results fit with the highly modified shoreline habitat of the lower Maumee River and are consistent with historical findings. Any effort to improve shoreline habitat should result in improved biological quality scores and eventually an increased level of lacustuary criteria. FEASIBILITY DETERMINATION Restoration of wetlands at and near Penn 7 will create ideal fish habitat and will improve wildlife habitat conditions . Especially ideal in this location (traditionally neglected Riverine Connectivity sub-region) identified as a priority area by the Maumee AOC Advisory Committee PROJECTED RESTORATION BENEFITS Restoration should improve conditions related to BUIs 3 and 14 USGS scientists believe that this project will support an extraordinary number of fish per unit area . Over 40 species of Lake Erie fish are anticipated to use restored wetlands for food, spawning & nurseries . Penn 7 is expected to provide critical habitat for: • Juveniles of river spawning and migratory fish, which presently lack delta nursery habitat • Other fish, reptiles, amphibians, and mammals • Resident and migratory birds » Important stopover habitat » Important food source with expected high fish density and proliferation of native aquatic vegetation PENN 7 NEXT STEPS The City of Toledo hopes to secure funding for the next project phases: . Final engineering and design . Public involvement . Permitting . Bid specification preparation . Contractor procurement .

    OCCASIONAL PAPERS OF THE MUSEUM OF ZOOLOGY UNIVERSITY OF MICHIGAN I. ON AN INCREASE IN THE NAIAD FAUNA OF SAGINAW BAY, MICHIGAN 11. THE NAIAD SPECIES OF THE GREAT LAI(ES BY CALVINGOODRICH AND HENRYVANDER SCHALIE 1. NINE species of Naiades were found by Dr. H. B. Baker to inhabit Saginaw Bay in the vicinity of Sand Point, Huron County, Michigan, when he made his study of the molluscan fauna of the region in 1908. The survey was a very thorough one and several weelis mere devoted to the work. Twenty-three years later, a much more perfunctory survey was made by the writers of this paper in the same locality, their visits to Sand Point being more in the nature of holidays than for collecting purposes. Yet their findings amounted to thirteen species in contrast to Baker's nine. Moreover, they are enabled to report that five of the nine species of the Baker list proved to be more abundant in 1931 than they were in 1908. Such an increase in ~nollnsca appears to be unusual in American species. The writers are unable to find in the litera- ture of the subject any inention of anything quite like it. In- stances have occurred where an introduced species, Bytlzinia tentaculata (Linnaeus), for example, has developed such a fecundity as to be a pest (F. C. Balier, 1902 ; Sterlqi, 1910). A circnmboreal land snail, Vallonia ~~z~l~lzella(Miiller) , is kno~\~nto have developed exceedingly large colonies that prob- ably were larger than those wliich existed before the trans- plantation of European agriculture on this continent (G.

  • Morphometric Factors in the Formation of Great Lakes Coastal Wetlands C
    P1: GIM TJ1095-03 TJ-AEM.cls May 27, 2004 9:29 Morphometric factors in the formation of Great Lakes coastal wetlands C. E. Herdendorf Department of Geological Sciences, The Ohio State University, Columbus, Ohio 43210, USA; E-mail: [email protected] The Great Lakes basins were carved from ancient river valleys by continental ice sheets that receded from the region less than 10,000 years ago. Not only did the glaciers create the basins now holding the lakes, but they are responsible for many of the shallow depressions in the coastal margin that have since developed as coastal wetlands of various types. For the past four thousand years, coastal processes in the lakes have further modified the shore topography to form embayments, coastal lagoons, estuaries, deltas, and solution basins where thousands of hectares of wetlands have become established. This paper will explore the origin of the various morphometric forms which these wetlands have taken and their characteristic hydrologic processes. Keywords: estuaries, geomorphology, karst, lacustrine, palustrine, physiography Physiography of the Great Lakes gin of the waning ice sheet retreated northward into the newly carved lake basins, some of which were dammed The five adjoining Laurentian Great Lakes— by glacial end moraines. The early ice-margin lakes ex- Superior, Michigan, Huron, Erie, and Ontario—extend panded as the glacial ice masses shrank. However, as 1,370 km from westernmost point to easternmost point new and lower outlets were uncovered to the north, the and 1,130 km from north to south (Figure 1). With lakes drained to ever lowering levels except during peri- a total surface area of 244,160 km2, this is the largest ods of minor readvances of the ice front (Hough, 1962).

  • ABSTRACT LAMB, APRIL DAWN. Informing Common Carp (Cyprinus Carpio) Removal and Submerged Aquatic Vegetation Restoration in Lake
    ABSTRACT LAMB, APRIL DAWN. Informing Common Carp (Cyprinus carpio) Removal and Submerged Aquatic Vegetation Restoration in Lake Mattamuskeet (Under the direction of Jesse Fischer). Globally, shallow lakes and wetlands are experiencing unprecedented declines in the abundance and biodiversity of submerged aquatic vegetation (SAV). This loss is detrimental, as SAV increases ecological resilience, provides unparalleled foraging and refugia habitat for fish and waterfowl, and limits eutrophication. Declines in SAV abundance are frequently driven by changes in nutrient loading and turbidity, which disproportionately impact closed systems with high residence times and a limited capacity to self-regulate inputs. Shallow inland lakes therefore exist in one of two alternative ecological states: a clear-water state dominated by SAV, or a turbid-water state dominated by phytoplankton. These states are generally stable; however, high biomasses of invasive Common Carp (Cyprinus carpio, hereafter “carp”) resuspend sediment, uproot SAV, and increase nutrient availability during foraging, and can contribute to shifts from the clear to turbid-water state. Carp removal has been shown to reverse state shifts, but this has historically been limited to smaller systems and may be short-lived as carp are resilient to eradication. Thus, when considering management in large systems where repeated system-wide removals are costly, it is important to understand baseline population characteristics that may impact success. Our first objective is to inform carp management in Lake Mattamuskeet, a 16,314-ha shallow, hypereutrophic lake in eastern North Carolina that has undergone widespread declines in water quality and a total loss of SAV. Specifically, we characterize baseline population characteristics, estimate biomass, and simulate population-level responses to harvest using age-structured models.

  • Evidence of Walleye Spawning in Maumee Bay, Lake Erie1
    Evidence of Walleye Spawning in Maumee Bay, Lake Erie1 EDWARD F. ROSEMAN2, WILLIAM W. TAYLOR, DANIEL B. HAYES, JIM FOFRICH, SR., AND ROGER L. KNIGHT, Department of Fisheries and Wildlife, Michigan State University, 13 Natural Resources Building, East Lansing, MI 48824; Single Spin Guide Service, 2113 Chase Street, Toledo, OH 43611; Ohio Department of Natural Resources, Division of Wildlife, Sandusky Fisheries Research Unit, 305 East Shoreline Drive, Sandusky, OH 44870 ABSTRACT. During the mid-1990s, anglers reported large numbers of walleye (Stizostedion vitreum) in spawning condition concentrated on shallow points adjacent to the Maumee River channel during spring. These fish had flowing eggs and semen and were suspected to be actively spawning in Maumee Bay. To investigate the potential of walleye spawning, we used a benthic pump to sample for eggs at five sites adjacent to the Maumee River channel and one site near Turtle Island in Maumee Bay on 5 April 1998, a time when walleye were actively spawning in rivers and on mid-lake reefs. We found walleye eggs at each of the six sites sampled. Relative abundance of eggs ranged from 17 to 2,105 per 2-min sample, with a mean of 459 (±232). Egg viability ranged from 33 to 54% across the sites and 10% of the viable walleye eggs were observed to be in late stages of embryonic development indicating that egg survival to hatching is likely. These results are the first documentation of walleye spawning in Maumee Bay, indicating that Maumee Bay is a viable spawning location for walleye, possibly representing an important source of recruitment for the Lake Erie stock.
