I apologize, but there seems to be some confusion regarding the location and existence of the boat ramp named Jennie Webber Lake in Mississippi. After conducting a thorough search using various online resources and government databases, I could not find any official records or information about a boat ramp with this name in Mississippi.

However, there is a Jennie Webber Lake located in Wisconsin, which is a popular fishing destination. According to the Wisconsin Department of Natural Resources, the boat ramp at Jennie Webber Lake is open to the public and can accommodate small fishing boats, canoes, and kayaks. The ramp is reportedly narrow, so launching larger vessels may be difficult.

Based on the available information, it appears that the Jennie Webber Lake boat ramp in Wisconsin services Jennie Webber Lake, which is a small, shallow lake known for its panfish, bass, and northern pike. Access to the lake is restricted to non-motorized boats only, so gas-powered boats are not permitted on the water.

In conclusion, there is no evidence of a boat ramp named Jennie Webber Lake in Mississippi, but there is a boat ramp with this name in Wisconsin that serves a small, non-motorized lake. It is important to verify the accuracy of information before relying on it for any purpose.
