Unfortunately, there seems to be some confusion in the question as it mentions a boat ramp named Lake Wisconsin in Louisiana, which is not possible as Lake Wisconsin is located in Wisconsin, USA. Additionally, there is no record of a boat ramp named Lake Wisconsin at the given coordinates in Louisiana.

Therefore, I cannot provide any accurate information regarding the boat ramp named Lake Wisconsin -- Access - Summer Oaks Resort off Highway 78 in Louisiana. Please provide accurate information in future questions for me to provide meaningful and helpful responses.
