June 28, 2001

Final Reports Available for Ohio Lake Erie Protection Fund Projects

The Ohio Lake Erie Commission announces Final Reports submitted this quarter for the Commission's Lake Erie Protection Fund grant projects are now available upon request. The five projects are listed below. 

These final reports will be available for viewing at the Library of the Ohio Lake Erie Commission Office in Toledo and the Ohio Environmental Protection Agency's Resource Center in Columbus. To receive a copy of a specific report, please contact the Commission Office at oleo@www.epa.state.oh.us or call 419/245-2514.

The Lake Erie Protection fund was established in 1992 to help finance research and implementation projects that help protect and preserve Lake Erie. During the last nine years, the Commission has awarded over $5.3 million in Lake Erie Protection fund monies for extensive projects that focus on improving the quality of Lake Erie and its watershed. This revenue is generated from monies received through the Lake Erie License Plate Program and Ohio's participation in the Great Lakes Protection Fund.

The Ohio Lake Erie Commission is comprised of the directors of the Ohio Environmental Protection Agency and the Departments of Natural Resources, Transportation, Development, Health, and Agriculture. The Commission was established for the purpose of preserving Lake Erie's natural resources, protecting the quality of its waters and ecosystem, and promoting economic development of the region.

ABSTRACTS

1)	LEPF 98-16
Modeling Nutrient-Enriched Sediment Transports During Coastal Erosion Processes, Rongxing Li, Ph.D., Project Director and Researchers: T. Ali, R. Ma and Dr. K. Di, Departments of Civil and Environmental Engineering and Geodetic Science; The Ohio State University, Columbus, OH.

This study focused on modeling contaminated sediment transport during coastal erosion processes and treating shoreline erosion as a source for the coastal sediment. This project developed and demonstrated a method that uses high-resolution satellite images to precisely map the Ohio Lake Erie shoreline and shoreline changes. Through the project of an 11km shoreline from Sheldon Marsh to Vermilion, OH, a new technology was demonstrated for mapping the entire shoreline and shoreline changes of Ohio's Lake Erie. The shoreline change monitoring methods developed are effective in quantifying the coastal erosion and environmental changes. Based on the accurate observations, a new approach has been developed to characterize and monitor the direct transport of nutrient-enriched sediments, including phosphorus, during the coastal erosion process. GIS-based models have been developed in this study that can estimate cell-based runoff depth soil-based phosphorus mass, and indirect surface soil transported sediment. 

2)	SG 32-96
Impact of Round Goby (Neogobius Melanostomus) Invasion on Zebra Mussel-Dominated Hard Substrate Communities, Ken Baker, Ph.D., Project Director, Department of Biology, Heidelberg College, Tiffin, OH.

The principal result of this study was the establishment of an on-going long-term investigation of the spread of an exotic benthic fish species, the round goby in Lake Erie. The first gobies in Lake Erie were observed by Ohio EPA in 1993; the species now is found in all the Great Lakes. It is a benthic fish that can attain very high abundances in its preferred habitat of shallow-water, zebra-mussel dominated, hard-bottomed surfaces. The objective of this project was to document possible ecological impacts of the goby's invasion of hard-substrate, shallow-water benthic communities. The specific intent of this project was to develop methods for monitoring biotic changes within a set of study sites to be established in the lake's central basin during the summer of 1996, and to re-survey these sites in early spring of 1997.

3)	SG 84-98
DNA Microsatellites to Identify White Bass Stocks in Lake Erie, Dr. Jeffrey G. Miner, Project Director, Department of Biological Sciences, Bowling Green State University., Bowling Green, OH.
 
White bass is an important sportfish in Lake Erie that uses tributaries (and reefs) in which to spawn, but the population size has been reduced substantially from unidentified mechanisms including fishing pressure, introduced species (white perch), and changes in water quality. The goal of this exploratory project was to determine if primers that have been used with striped bass, a congener of white bass, could be used to identify polymorphic microsatellites in white bass. In addition, the project was to determine if any potential differences in the allelic frequencies between several populations of white bass in Lake Erie could be identified.

4)	SG 110-99
Changes in Plasma Levels of Free and Conjugated 17,20B-Dihydroxy-4-Pregnen-3-One During Final Maturation of Yellow Perch (Perca Flavescens), Dr. Konrad Dabrowski, Project Director and Dr. J. Rinchard, School of Natural Resources-The Ohio State University, Columbus, OH.

This study was conducted on yellow perch caught on April 4, 1999 in commercial trap nets from the western basin of Lake Erie. Fish spent up to 96 hours in the trap nets at approximately 30 feet depth. All males sampled were spermiating. The levels of plasma T and 11-kT were high in comparison to the period prior to spermiation. The concentrations of both androgens did not differ significantly. A positive correlation was found between those two androgens. Among the 15 females sampled, three had already spawned. GSI was significantly higher in pre-ovulating females than the ones in the post-spawning stage. The plasma sex steroid levels were significantly higher in pre-ovulating females than in post-spawning yellow perch. This study concluded that steroid concentrations in feral yellow perch do not indicate any disturbances in the maturation process in this species.

5.)	SG 126-99
A Preliminary Survey of Wetland & Stream Restoration Sites in the Chagrin River Watershed, Thomas J. Denbow, Project Director, Chagrin River Watershed Partners, Inc., Willoughby Hills, OH.

The Chagrin River Watershed Partners, Inc. (CRWP) was formed in 1996 by 16 watershed communities to provide technical advice and assistance to local governments on land use related issues. CRWP serves 28 members including townships, villages, cities, counties, and park districts. This project is the first step in the CRWP's on-going effort to assist members in cataloging their existing wetland and stream resources, identifying candidate mitigation and restoration sites, and monitoring the cumulative impact of land use changes on the flood control, erosion control, and water quality protection services of the watershed's streams and wetlands. This project will also assist member communities in responding to federal and state regulatory changes impacting wetland and stream resources. The following tasks were done in developing the project: (1) establishment of a Technical Advisory Committee; (2) Review of decisions impacting Chagrin River wetlands and streams; (3) Inventory of completed and proposed projects; (4) Survey of existing watershed wetlands; and (5) Development of selection criteria and identification of potential mitigation sites.
