The video above iss a breif overview of the Fellsmere Reservoir also known as Headwaters lake in Fellsmere Fl.
This is an incredible fishery that was stocked with 1 million bass. There are plenty of 5-10 pounders in the lake and huge numbers of the 1-5 lb. fish.

There are no depth numbers on the map however it does give you a pretty clear idea of where the deep holes and the flats are. The deep areas are in blue and shallows in white.
