Overview
Lake Ontario is similar to Lake Erie in length and breadth (193 miles by 53 miles). Yet with its greater average depth (approximately 283 feet), Lake Ontario holds almost four times the volume (395 cubic miles) and has a retention time of about 6 years. The drainage basin covers parts of Ontario and New York, and a small portion of Pennsylvania. Major urban industrial centers, such as Hamilton and Toronto, are located on its shore. The U.S. shore is less urbanized and is not intensively farmed.
