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: 0.53 ft0.16 m Assuming the level stays the same was off by 0.72 ft0.22 m
Actual level inside our range: 72% of 432 tests; the range is built to catch 8 in 10
When we said a rise was possible (20–40%): 28% of those 32 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 Joe Pool Lake

Joe Pool Lake is a U.S. Army Corps of Engineers reservoir on Mountain Creek in the southern Dallas-Fort Worth area, spanning Tarrant, Dallas and Ellis counties. The dam was completed in the mid-1980s for flood control and water supply. It is named for Congressman Joe R. Pool, who pushed for the project. Mountain Creek Lake is just downstream.
