Watts Bar Lake tomorrow
A forward-looking outlook for planning a Watts Bar Lake outing tomorrow. Built from the next 24 hours of National Weather Service hourly forecast data, TVA's published 3-day generation schedule, and the live water-temperature reading from the dock probe. Re-rendered every minute as the inputs update.
Wind window
Forecast peak sustained 8 mph, averaging around 5. Calm enough for any boat in any cove.
TVA generation pre-schedule
TVA shows 1 of 5 generators expected to run at Watts Bar Dam tomorrow, predicted average outflow 5,280 cfs. Schedule can change without notice; verify before launching tailwater.
Where to launch
Calm forecast. Any ramp works; pick one based on where you want to fish. All ramps are listed with directions.
What's likely biting
Water is at 69.4°F, in the typical 65–75°F range for May. The active species this month are Largemouth Bass, Smallmouth Bass, Bluegill & Shellcracker (Redear). Look around shad-spawn banks, grass edges, isolated milfoil/hydrilla.
How this is built
The wind window comes from the NWS hourly point forecast for our specific grid cell. The TVA pre-schedule comes from TVA's predicted-data REST endpoint, the same data that drives TVA's own lake-info app. The ramp recommendation matches tomorrow's expected sustained wind against a wind-protection score on each public ramp; sustained over 25 mph routes you to a sheltered embayment ramp like Caney Creek or Spring City. The species call uses the current water-temperature reading and the seasonal pattern in the fishing knowledge base; species recommendations do not change minute-to-minute, so the page caches them per day.
None of this is binding. The forecast can be wrong. TVA can change generation on short notice. Wind picks up faster than the model expects. Treat this as a starting point, then check again in the morning before you launch.
