Gilboa Quarry
Gilboa
Quarry is 14+ acre stone quarry, located in Northwest Ohio. There are wooded
campgrounds encompassing over half of the quarry's
perimeter. This quarry is a great location for
diving and dive training. The quarry provides two distinct personalities: the
shallow side at 5-65 ft provides great recreational enjoyment, while the deep
side of the quarry with cold, dark depths of 120+ ft is suitable for technical
training. The Shallow side offers a variety of underwater sites
including a jet plane, a bunch of boats, some cars and a ton of really friendly
fish. There are a lot of aggressive and fun to swim with trout and a real
treat is the elusive Paddlefish. These awesome 5' plus fish will really
take your breath away.
The quarry is open year round and in the winter the
visibility can reach 100ft or more. In the summer the visibilities
diminish slightly and the place gets really crowded. Bring along
your patience in the summer because parking is scarce and if available it is a
little pricey so you may have to drop off your gear and park in the main lot.

Worth a little aggravation, Gilboa Quarry provides a variety of amenities to
meet your specific diving needs. Docks, benches, and underwater platforms are
provided for your convenience, be it Open Water certification dives, enjoying
the underwater sites, or to keep your skills honed for your personal diving
goals. The management of the quarry has done a top notch job of providing
enjoyable underwater sites and above water conveniences. There are bunk houses
and showers available as well as flushing toilets. In the winter all of
the changing rooms are kept well heated.
Breathing Gas is available onsite. Up to 20,000cf of hyper-clean air is banked
to provide for those peak periods when we all want to get wet. Be sure to check
your VIP and hydro dates on your cylinders prior to coming out to the quarry.
Partial pressure Nitrox blending is available for tanks that are O2 clean.
