Inflow forecast

modeled

NOAA’s National Water Model, short-range run issued Nov 14, 3 PM CST, for the 2 gauged tributary reaches feeding Lake Texoma. The model includes rain that has already fallen plus the near-term rain forecast.

Dashed lines are forecast. Values are at the gauges; water takes hours to a couple of days to get from there to the lake. National Water Model via NOAA/NWS · public domain.

The “net lake effect” is the forecast inflow volume minus the water leaving the lake now (44 cfs, Red River at Denison Dam, right now), held steady over the forecast period and spread over today’s surveyed surface area (TWDB) (before releases it would be +0.02 ft). It ignores travel time, channel losses and any change the dam operators make, so it gives a sense of scale, not a prediction. During floods, watch the main page instead.
