Airy Gators & Other In-Lake Treatments
St. Marys Boat Club ~ Edgewater Drive
An Airy Gator is a large, floating electric-powered
aerator with a series of rotating discs that infuses
dissolved oxygen onto the lake’s bottom enabling
beneficial micro-organisms to grow and consume
nutrient-rich organic material in the sediment. By
naturally reducing the amount of organic material at
the bottom of the lake, a reduction in both algae and
toxins is expected. This stop will highlight what is
being done in-lake to address water quality concerns.
Restroom facilities are available next door at the
Auglaize/Mercer Convention and Visitor’s Bureau.
Rough Fish, Alum and Dredging
Otterbein St. Marys Senior Life Style Community
11230 SR 364, St. Marys
ODNR staff will provide demonstrations on rough
fish removal and alum treatment. Learn how the
dredging process works and see firsthand the newest
suction dredge, Brutus, in action.
A step toward improving water quality in GLSM
occurred this spring when an alum treatment was
applied to cover the entire lake. This treatment, in
addition to rough fish removal, dredging, installation
of a treatment train, wetland creation, and watershed
improvements, is an integral part to improve GLSM.
ODNR ensures a balance between wise use and
protection of our natural resources for the benefit of
all. Visit the ODNR website at www.dnr.state.oh.us.
Brownhaven Dairy Farm

Brownhaven Farm is a family dairy operated by
Lou and Alan Brown along with their families. They
have 220 registered Holstein cows and 150 heifers.
The family raises crops to feed to their livestock.
The Browns are taking many steps to protect and
preserve land, air and water resources, including
planting wide areas of grass along waterways on the
farm, maintaining wetlands and planting cover crops.
They also use no-till practices to prevent erosion and
recycle nutrient-rich manure from the cows to nourish
their crops. They have planted a quail buffer along
wooded areas to encourage wildlife habitat.
The Brown family pride themselves in being good
stewards of the environment, particularly because the
farm sits just 3 miles from GLSM.
committed to what’s right for future generations of
their families, neighbors, and community.

Edge of Field and Tile Monitoring Station
Depweg Road West of US 127
Several farmers in the Beaver Creek and
surrounding subwatersheds of GLSM have partnered
with Kevin King of USDA’s Agricultural Research
Service to install tile and surface monitoring stations
to facilitate water quality data collection. Farmers
want to know exactly what is running off the field.
This stop gives insight to quantifying what is happening
at the edge of the field and at the end of the pipe.
agriculture programs allow for sampling based on using
specific grid patterns within a field. Mercer Landmark
