IIRC, when we went, Mike Vernon paid the $6 usage fee for all 4 of us but did not pay for fishing licenses, Still, the $6 seemed high compared to Poplar Tree Lake.
It's my impression that the lake is very popular with hikers, mountain bikers and fishermen.
Here are some statistics from the internet -
Herb Parsons Lake is a Reservoir lake located in Fayette County, Tennessee near the town of Eads. The lake is named after Herb Parsons an exhibition shooter. It is known primarily for its fishing, hiking and bicycle trails, and wildlife.

Poplar Tree Lake is listed as 125 acres, so Herb Parson;s is bigger.
