After conducting a thorough search, I was unable to find any information regarding a boat ramp named 8th Street East 952 in Thief River Falls, Minnesota. It is possible that this boat ramp may not exist or that it is a small, lesser-known ramp that has not been widely publicized.

Without any information to go on, I am unable to answer the questions posed in the prompt, such as what kind of boat ramp it is, how wide it is, which body of water it services, and what kind of vessels are permitted to launch from it.

In the absence of information about this specific boat ramp, it is worth noting that Minnesota is home to many boat ramps and launches that provide access to its numerous lakes and rivers. Some of the more popular boat ramps in the state include Elm Creek Park Reserve Boat Launch, Lake Phalen Boat Launch, and Coon Rapids Dam Regional Park Boat Launch. Most boat ramps in Minnesota are designed to accommodate a range of watercraft, including powerboats, sailboats, canoes, and kayaks. The width of the ramp and the type of watercraft allowed may vary depending on the location and the body of water it services.

Overall, while I was unable to find information about the 8th Street East 952 boat ramp in Thief River Falls, there are many other boat ramps in Minnesota that offer access to its beautiful waterways.
