Lake Weohyakapka, Lake Wales: The 9,500-Year-Old Toolkit on the Lake Bottom

Shallow lakes like this one were not always lakes. During the late Pleistocene and early Holocene, when the Florida peninsula was wider, drier, and the water table was much lower than it is now, what is now Weohyakapka's basin was likely a series of shallow ponds, marshes, and exposed flats clustered around freshwater seeps. That made it exactly the kind of place Paleoindian people came to. Game came to drink. Stone could be worked at the water's edge. When somebody dropped a tool, or finished using one and left it, the wet sediment swallowed it before it could weather away. Then the climate warmed, the water table rose, the basin filled, and everything that had been left on those ancient shorelines went under and stayed there.

Microlithic tools are small — flakes, blades, and scrapers worked from chert, often less than an inch or two long, used for fine cutting, hide-working, and hafting into composite tools. They are easy to miss. To find a single one is unusual. To find the largest assemblage in the state, in one lake, suggests sustained occupation: people returning to the same spot for generations because the water and the game and the stone were reliably there.

What is sitting under your boat, in other words, is older than the pyramids by about four thousand years. Older than agriculture in most of the Americas. The bass you are trying to catch are swimming over a workshop floor.

The lake's modern reputation has nothing to do with archaeology. Weohyakapka is one of Florida's premier trophy largemouth bass fisheries, the kind of lake that anglers drive hundreds of miles to fish. Thirteen-pound bass have come out of it. The fishery struggled through a stretch of overharvest before catch-and-release rules tightened it back up, and today it produces what guide Johnny Doub once described as an "absolutely incredible" number of eight- to twelve-pound fish. The shallowness that preserved the tools is the same shallowness that grows the vegetation that grows the bass.

The shoreline has stayed mostly undeveloped. Indian Lake Estates sits on the western edge — a 1955 development that never came close to its planned 15,000 residents — and the Walk-in-the-Water tract of Lake Wales Ridge State Forest covers a lot of the rest, scrub habitat for Florida Scrub-Jays and bobwhites. The SUMICA tract, on the southern end, preserves what was once a logging town and sawmill. There is a public boat ramp and not much else. No marina row. No condo wall. The lake looks, from most angles, about the way it has looked for a long time.

That matters for the tools. The reason an archaeological site of this scale is still legible at the bottom of a Florida lake is that nobody has dredged it, channelized it, seawalled it, or built a causeway across it. The basin has been left alone to do what shallow basins do, which is hold onto things.

Most lakes in this part of the state tell their oldest story through a name on a sign or a plaque near a boat ramp. Weohyakapka tells it through what is actually still down there — flakes of worked chert, in the muck, under twelve feet of water, where somebody left them before there was a Florida to leave them in.
