INTRODUCTION

 

Aquatic vegetation in luxuriant amounts and of many forms is observed by the canoeing bass angler float-fishing along with the swift currents of the Ocklawaha River. The following list contains 20 or so of the aquatic plant species that inhabit the mainstream waters of Marion County's free-flowing Ocklawaha River--between Lake Ocklawaha (Rodman Pool/Rodman Reservoir) and the inflow of Silver River. Some of these identified plants occur much more abundantly than others from the list in this "middle" section of the river. Silver River and the "lower" Ocklawaha River downstream of Rodman Dam (Kirkpatrick Dam) would exhibit most of the same in-stream vegetation.

BASS FISHING OUR FREE-FLOWING RIVERS AND CREEKS

 

Experienced stream anglers know that the highly prized game fishes of the South's creeks and rivers--whether they be cold-water rainbow trout in the tumbling, free-stone mountain brooks of the Blue Ridge or largemouth bass in the cypress-lined, 73-degree F limestone spring runs of Florida--"hold" in a suitable area where they can face upstream to watch for any downstream-moving prey while being prepared to quickly ambush and eat it. In-stream rocks and submerged portions of natural wood (tree branches, "stobs", and trunks) along with undercut river banks are prime current-breaking, holding cover for all forms of riverine freshwater bass (black and/or striped). As far as fishing in swift-flowing rivers is concerned, the emergent and submerged water plants growing at a depth of from 3 to 8 feet are probably the most important aquatic "weeds" for largemouth bass structure. Surface-floating and/or top-matted water plants are normally less significant as bass-attracting habitat in streams because they offer very little strategic interruption of the current flowing beneath them.
