Information courtesy of Upper Thames River Conservation Authority (UTRCA): 

The water in the quarry originates from groundwater discharging from fractures or cracks in the bedrock, and from precipitation. Groundwater is always cold, staying within a few degrees of 10˚ Celsius, year round. As a result, the water in the quarry is cool during the swimming season and relatively warmer in the winter.

Groundwater levels are also fairly constant, varying only about 1 metre over the course of a year. Groundwater is at its highest in the winter/early spring, and relatively stable throughout the summer. During hot summers, water levels in the quarry may drop slightly due to increased evaporation and surface water temperatures may be warmer.

Water depths in the quarry range from 3 to 10 metres.

The main fish species found in the quarry are Common Carp, Pumpkinseed and Rock Bass. The fish are able to migrate between the west quarry fishing hole across the street and the quarry through the underwater tunnel connecting the two. In an open watercourse, species like Common Carp and Pumpkinseed would move to warmer portions of that waterbody. However, they are still able to survive in the colder water temperatures found in the Quarry.

Common Carp

The Common Carp is a large, deep-bodied fish, varying in colour from silver to olive-green, brass or grey on the back and sides. It has whisker-like appendages called barbels near the corners of its mouth. Native to Asia, carp were introduced to North America from non-native populations in Europe. Common Carp adapt to a variety of conditions, tolerating all types of bottoms and water clarity ranging from clear to murky.

Pumpkinseed

The Pumpkinseed is a very deep-bodied, laterally compressed, almost disk-like fish. The fish’s breast and belly are orange to red-orange, and its back and sides are brown to olive. Its sides and back are speckled with orange, yellow, blue, and emerald spots. Pumpkinseeds can be found in large schools and often make up the largest portion of the fish population in small, warm bodies of water. Part of the sunfish family, the Pumpkinseed is native to eastern North America.

Rock Bass

The Rock Bass is a small and very deep-bodied fish. Its back and upper sides are brown to olive with golden tints, and often with dark saddles. It has a large red eye and its mouth is large and extends backwards to below the middle of the eye. The Rock Bass is part of the sunfish family and can be found swimming with other sunfish and bass. It is a cool-water fish native to Ontario.
