Inflow forecast

model output — not a measurement

NOAA’s National Water Model, short-range run issued Jul 14, 10 AM CDT, for the 2 gauged tributary reaches feeding Lake Texoma. The model routes rainfall that has already fallen plus near-term forecast precipitation.

Dashed = forecast. Values are at the gauges, not at the lake — water takes hours to a couple of days to travel downstream from the gauges to the lake. National Water Model via NOAA/NWS · public domain.

The “naive lake effect” spreads the projected inflow volume over the lake’s estimated current surface area, ignoring travel time, channel losses, upstream storage decisions, and releases — it is a scale reference, not a prediction of the actual lake level. During floods, watch the live dashboard instead.
