## Quick answer

The Ashbridges Bay Boat Launch has two concrete launch ramps with specific structural details and varying seasonal water depths.

## Detailed answer

The Ashbridges Bay Boat Launch features two concrete launch ramps designed to accommodate various watercraft. The ramps are constructed to withstand the fluctuations in water levels, which can range from 74.5 to 75.5 meters above sea level due to the regulation of Lake Ontario's water levels by the International Lake Ontario-St. Lawrence River Board. The water depth at the launch area varies seasonally, with depths typically ranging from 6 to 8 feet (1.8 to 2.4 meters) in Coatsworth Cut. During periods of low water, the channel may be as shallow as 4 feet (1.2 meters), while high water levels can result in depths exceeding 10 feet (3 meters). It is essential for boaters to be aware of these changes to navigate safely. The City of Toronto updates the water depth information on their website and at the launch site. Boaters should check these sources before heading out to ensure they have the most current information. Additionally, the ramps are designed with a gentle slope to facilitate easy launching and retrieval of boats, with a width of approximately 30 feet (9 meters) to accommodate multiple users. The launch ramps are also equipped with lighting for safe nighttime use.
