How well this outlook has done here

We tested the 2-week outlook on past years at this lake, as if made once a week with only what was known that day.

On average it was off by: 0.80 ft0.24 m Assuming the level stays the same was off by 1.01 ft0.31 m
Actual level inside our range: 83% of 432 tests; the range is built to catch 8 in 10
When we said a rise was possible (20–40%): 35% of those 29 times it ended 1 ft0.3 m or more higher

The rise chance uses the same threshold for every lake: 1 ft (0.3048 m).

About Whitney Lake

Whitney Lake (Lake Whitney) is a U.S. Army Corps of Engineers flood-control reservoir on the main stem of the Brazos River in Hill County. Whitney Dam was completed in 1951 and controls runoff from about 17,600 square miles of Texas and New Mexico. Lake Granbury is upstream on the Brazos.
