Despite the rainy spring and early summer in the metro, watering restrictions remain in place in some cities.
Tim Cowdery, a Hydrogeologist with the U.S. Geological Survey, says what may have seemed like a lot of rain really wasn't.
"We had a really wet spring and early summer, which over the long term, is a very short period of time,” Cowdery said. He adds surface water fluctuations happen on a much shorter cycle, fluctuations in the groundwater occur on a much longer timetable.
In addition to circular changes to groundwater levels, Cowdery says high-use rates can deplete underground water supplies.
"When you see ground levels fall, it's a clear indication that the amount of water being pumped out is exceeding the water that's leaking in," Cowdery said.
Dean Lotter, city manager in New Brighton, says the city is trying to preserve water. "We do have odd-even restrictions in the city of New Brighton."
Lotter says water restrictions are in place to help overall conservation efforts. "So even though we've had a lot of rain, yes, that adds to the surface water, but that doesn't necessarily replenish the aquifers."
