...Abnormally Wet Start to August keeps Devils Lake Levels
An active weather pattern during the start of August has led to an
abundance of rainfall in the Devils Lake Basin. Normal rainfall
during this two-week period is around 1.25 inches. Rainfall during
this period has been well above normal with most areas receiving two
to five inches of rainfall. The added rainfall, combined with
extremely wet soils, contributed to high runoff and stream inflows
into the lake. The outlet pumping and the typical late-summer
evaporation effects have not offset the inflows and, as a result,
the lake levels continue to remain unseasonably high.
The water level at Devils Lake is currently around 1450.2 feet.
Considering the typical lowering of lake levels during the late
summer and the full capacity of the outlet pumps, the lake was
expected to be lower than the current level by this time.
Considering the above, the National Weather Service`s North Central
River Forecast Center, along with its Weather Forecast Office in
Grand Forks ND will update the Devils and Stump Lakes
Probababilistic Hydrologic Outlooks next week.
