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
0.88 ft0.27 m Assuming the level stays the same was off by 1.20 ft0.37 m
Actual level inside our range
86% of 432 tests; the range is built to catch 8 in 10
When we said a rise was possible (20–40%)
14% of those 22 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 Lake Travis

Lake Travis is the main flood-control lake of the Highland Lakes, on the Colorado River northwest of Austin, formed by Mansfield Dam in 1942. It stretches about 65 miles upriver to Max Starcke Dam near Marble Falls, and the Pedernales River enters it from the southwest. Because it takes in floodwater, its level has ranged nearly 100 feet between record low and record high, and it can rise many feet in a day after major storms.
