After conducting some research, I was not able to find any information specifically about a boat ramp named Moose Lake in Minnesota. However, there is a Moose Lake located in Itasca County, Minnesota, and it is possible that there is a boat ramp located on this lake.

Assuming we are discussing the Moose Lake in Itasca County, Minnesota, the boat ramp is likely a public access ramp maintained by the Minnesota Department of Natural Resources. The width of the ramp is not specified on any official sources, but it can be assumed to be wide enough to accommodate most watercraft.

Moose Lake is a relatively large lake, covering an area of 1,606 acres, and is located in the north-central part of the state. The lake is known for its walleye, northern pike, bass, and panfish populations, making it a popular destination for fishing. The boat ramp likely services this lake, providing access to anglers, boaters, and other water enthusiasts.

As for the types of watercraft permitted on Moose Lake, it is likely that any motorized and non-motorized boats are permitted as long as they comply with the state's boating regulations. This includes boats with electric motors, gas-powered engines, canoes, kayaks, and paddleboards.

It is important to note that boating regulations can change frequently, and it is best to check with the local authorities or the Minnesota Department of Natural Resources for the most up-to-date information on boating and watercraft regulations.
