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
- 0.21 ft0.06 m Assuming the level stays the same was off by 0.31 ft0.09 m
- Actual level inside our range
- 88% of 432 tests; the range is built to catch 8 in 10
The rise chance uses the same threshold for every lake: 1 ft (0.3048 m).
