During all dives at this location, you can expect to frequently see Bluegill and Redbreast Sunfish. Other commonly encountered species include Pumpkinseed, Smallmouth Bass, Largemouth Bass, and Rock Bass. Less common sightings include Carp, Black Crappie, and crayfish.
When planning your dive during the no-ice season, which lasts from May to June, be prepared for water temperatures ranging from approximately 50F/10C to 65F/18C. Despite the chilly conditions, this time of year offers the opportunity to witness the nesting behavior of Bluegill, Redbreast Sunfish, Black Crappie, and Bass. Underwater photography and videography are particularly popular during this period, as marine life tends to be more cooperative. Just remember to practice responsible underwater photo and video techniques to protect the well-being of the subjects. It's worth noting that during lake cleanups in this season, there may be trash debris within the nests that contains fish eggs. Unless you are certain the eggs have hatched, it is important not to remove any trash debris from the nests.
As the warmer months of July and August arrive, water temperatures rise to approximately 70F/21C to 80F/26C. During this time, divers may encounter fewer marine life sightings, as many fish relocate to deeper and colder waters. However, this presents an excellent opportunity to appreciate the captivating rock formations located south of the dive site. Alternatively, divers can choose to contribute to conservation efforts by searching for and removing trash debris in the area.
In September and October, the water temperatures rapidly cool down from 80F/26C to 50F/10C. Despite the cold, these lower temperatures bring remarkable changes to the dive site. The Black Crappie are often found lingering around Classroom Rock during this time, but they tend to be skittish and won't stay for long unless divers exhibit patience by remaining still for several minutes. On the other hand, the Smallmouth and Largemouth Bass become much more curious during this season, often approaching divers face to face or shadowing them as they explore the site. Additionally, the juveniles of various species are now larger and more visible, freely exploring their surroundings. As a result, underwater photography and videography remain popular during this period.
With a maximum depth of 6m, good visibility extending up to 3m, and a diver level recommended for beginners, this dive site offers an exceptional experience in the beautiful underwater world of Pittsfield, located in Berkshire County, Massachusetts, United States (01202).
