Scuba Diving at the Quarry

Brownstone Exploration and Discovery Park contains two freshwater
quarries. Currently the north quarry is open to scuba diving activities
on a regular basis. The south quarry will be available in the future
for more technical and specialized training opportunities as the park

The north quarry is a 27 acre brownstone quarry with beautiful views
of 80 to 100-foot brownstone cliffs. Water depths range to 85 feet. An
easy walk-in entry is available.


Visibility varies depending on the portion of the quarry is being
dived. Reports frequently range from 10 to 30 feet. This depends on
many factors and can never be guaranteed. Many areas of the bottom
contain silt and can stir up easily if one gets too close.

Water Temperatures

Water temperatures vary depending on the time of year. Surface
temperatures are in the mid-70s in the late summer and low to mid-30s
in the winter. Bottom temperatures in the deepest areas of the quarry
drop to the low-40s year round. Temperatures above 30 feet are usually
comfortable for divers in 7mm wetsuits, but many divers dive dry year

Wild Life

Fish frequently seen include Large Mouth Bass, Carp, Bluegills, Perch and an occasional American Eel.

Underwater attractions

Training platforms are installed at various depths. A navigation course
has been constructed with surface and underwater markers for practicing
compass skills. A number of abandoned vehicles and other items can be
found. Several of the abandoned motor vehicles will be removed and
other attractions will be submerged for your diving pleasure. We will
announce additions as they are added.
