Dive Report – Petawawa Barge & Bottle Dump (Village of Petawawa)
The Petawawa Barge & Bottle Dump site consists of two attractions located close together, upstream of the last set of rapids of the Petawawa River, just before it joins the Ottawa River in the village of Petawawa. The two sites are positioned in a sharp elbow of the river, where the current is reduced but still a factor to consider in planning the dive (a safety issue). Due to the main current of the river, it is recommended to visit this site only during the times when the river is at its lowest levels, such as August or September. The current’s positive aspect is that it keeps minimal silt at the site, and any silt that gets stirred up is quickly washed away.
The depth at the site ranges from 5’ to 10’, with an average of around 6’. This site can be snorkeled, but to explore the bottom, scuba diving is more comfortable. Despite the shallow depths, a 72 CF steel tank can last over an hour. The river bottom varies between washed sand/gravel and stacked logs, providing an excellent habitat for fish. However, during spawning season, the strong current can be hazardous, especially as the site is situated above a set of rapids.
Visibility (VIS) is generally good at this site (~15’) due to the shallow depth and fairly clear water. However, after heavy rains, visibility can be reduced as storm sewers empty into the river. The water temperature is typically warm in the summer, ranging from 20 to 28 degrees Celsius, and there is no thermocline at this site.
The main attraction of the site is the abundant marine life, including bass, sturgeon, and gar pike. The site is a popular fishing spot, resulting in many fishing lures being found on the logs. However, caution should be taken to avoid fishing lines that may be draped everywhere.
The Petawawa Barge is a large wooden structure resembling a barge, approximately 60’ long, 20’ wide, and 6’ deep. It is mostly filled with sand and sits upright on the sandy bottom. The deck is in shallow water, allowing views of the hull cavity and interior. The barge’s original purpose remains unknown.
The Bottle Dump is likely a spot where early residents disposed of domestic waste, leaving behind bottles, boots, cans, plates, and glasses. Over time, the river current washed away lighter objects, leaving glass and ceramic materials. Many bottles are hand-blown and some are quite old, providing an interesting glimpse into history.
Access to the site is excellent, as it is located within the village of Petawawa with public access to the river. However, the main hazards are the river current (at certain times of the year) and the shallow depth. The site is particularly unsafe during periods of strong current, but it can be a rewarding experience to explore during calmer times.
Overall, the Petawawa Barge & Bottle Dump site is worth visiting, and there is a variety of attractions for divers and snorkelers to enjoy. However, caution should be exercised, especially during times of strong current and when exploring the glass-filled Bottle Dump. It’s advisable to check out antique bottle websites to gain knowledge on dating bottles before visiting the site.
