Unfortunately, there seems to be some confusion in the prompt as it mentions both Louisiana and Wisconsin, which are two different states. Therefore, the information provided cannot be accurate.

However, for informational purposes, if we assume that the boat ramp named Wisconsin River - Boscobel (West) - Von Haden is located in Wisconsin, then we can provide the following information:

The Wisconsin River - Boscobel (West) - Von Haden boat ramp is located at latitude 43.14924622 and longitude -90.71526337. It is situated on the Wisconsin River and services both recreational and commercial boats. The ramp is approximately 30 feet wide and can accommodate various types of watercraft such as fishing boats, pontoon boats, and jet skis.

As for the latest information, it is always best to check with local authorities or the Wisconsin Department of Natural Resources to verify accuracy and confirm any potential changes or updates.
