Based on available information, Massey Branch Boat Launch is a public boat ramp located in Winston County, Alabama. It provides access to the Upper Bear Creek Reservoir, a 1,400-acre lake created by the Bear Creek Dam.

The boat ramp is reportedly 16 feet wide, which may make it suitable for launching smaller boats and watercraft. However, it is uncertain whether there are any additional facilities or amenities at the site, such as parking or restrooms.

As for the types of watercraft permitted on the Upper Bear Creek Reservoir, it appears that boaters are allowed to use a variety of vessels, including motorboats, kayaks, canoes, and paddleboards. However, it's worth noting that the reservoir is managed by the Alabama Department of Conservation and Natural Resources, which may have specific rules or regulations regarding watercraft and other activities on the lake.

Overall, while there may be some limitations or restrictions on the use of Massey Branch Boat Launch and the Upper Bear Creek Reservoir, it seems to be a popular destination for fishing, boating, and other recreational activities in the Winston County area.
