Grand Lake St. Marys St. Park
Constructed as a feeder lake for the Miami-Erie Canal, Grand Lake St. Marys, at its completion in 1845, was the largest man made lake in the world.  The feeder reservoir was formed by raising two walls of earth, from ten to twenty-five feet high, called the East and West embankments.  These walls formed a high basin to retain the water.  The reservoir rests on the summit between the Ohio River and Lake Erie.  Now Ohio’s largest inland lake, Grand Lake St. Marys is a prime recreational area offering a variety of activities for the whole family.  With over 13,500 acre and 52 miles of shoreline ( much of it accessible to the public), Ohio’s Other Great Lake provides many opportunities for picnicking, swimming, fishing, boating, skiing, tubing and camping at Grand Lake St. Marys State Park. http://www.dnr.state.oh.us/parks/grndlake/tabid/737/Default.aspx

Boating - Grand Lake St. Marys is open zoned for skiing and has unlimited horsepower for power boating.  A 300 foot “no wake” zone provides for safety and shoreline protection.  There are five state operated launch ramps providing boaters access to the lake.  Private launch ramps are also available at marinas along the shallow shoreline.  Sailing and jet skiing are very popular on this grand lake..

Fishing - Fishing is a year around affair on Grand Lake St. Marys.  Since the lake is shallow (average 7-9 ft. In depth), it warms quickly in the spring activating large mouth bass and large catches of bluegills and crappies.  There are professionally run and organized fishing tournaments held every year.  The lake is considered one of the finest “pan fishing” area’s in the state, with good populations of crappie and yellow perch.  Walleye fry and fingerlings have been stocked and a significant walleye population is developing with good sized walleye  reported being caught.

Bird Watching-Grand Lake St. Marys lies along one of the country’s major migration routes.  Water birds using the lake as a resting stop include Canadian geese, ducks, grebes, swans, egrets, loons, herons, cormorants and ospreys.  Many ducks, eagles and herons also nest at Grand Lake St. Marys. Currently the lake also boasts two nesting pair of bald eagles along the south side.

Veteran eagle watcher Jill Bowers reports the newest nesting pair is 3 ½ to 4 years old. This is probably their first nesting season, according to Jill, so they are not very experienced at raising eaglets.  That nest is due to hatch by April 10th.

The veteran pair has again selected the nest in the Mercer Wildlife Area, using the same nest for the past two years where they have hatched triplets both years.  They began incubating in early February and should be hatching any day now.

To date, Mercer County has increased the Bald Eagle population in Ohio by twelve since the first pair arrived in 1995.
