What bay is located 13 miles southwest of Oswego?

Little Sodus Bay is the correct answer because it is indeed located approximately 13 miles southwest of Oswego, making it the nearest notable bay in that direction on the eastern shore of Lake Ontario. This bay is known for its sheltered waters and is a popular spot for recreational boating and fishing, contributing to the local economy and tourism.

In contrast, Mexico Bay, while also located on the eastern shore of Lake Ontario, is situated further west than Little Sodus Bay and does not fit the specified distance. Burlington Bay is located on the northern shore and does not align with the southwest direction from Oswego. Black River Bay, on the other hand, is located further east and is not in proximity to Oswego. These factors help clarify why Little Sodus Bay is the appropriate choice for this question.
