Water

Water shortages and problems around Minnesota — and the country — have many wondering what is the true cost of clean and reliable water. This reporting is supported in part by The Water Main, a project of American Public Media.

Finding climate history in the river bottom
The current drought is helping researchers who are studying the history of flooding in the Red River Valley. They’re collecting samples of old trees buried in the muddy river bottom to help build a regional climate picture going back hundreds of years.
Researchers from Minnesota and Wisconsin are trying to figure out precisely what has caused the recent spike in blue-green algae blooms in Lake Superior. Six algae blooms have been discovered in the past decade between Duluth and the Apostle Islands, including one scientists just confirmed this summer.
Drought threatens to empty water wells in parts of Minnesota
Parts of Minnesota saw much-needed rain over the weekend, but it wasn't enough to break the ongoing drought. And the abnormally dry conditions are threatening some private water wells that rely on rain to recharge. In severe cases, shallow wells are out of water.
Swimmers discover zebra mussels have invaded more Minnesota lakes
About 3 percent of Minnesota lakes are infested with zebra mussels, although that number has been growing. They can compete with native species for food and habitat, change the ecology of the lake, cut swimmers’ feet and cause damage to water intake pipes.
New effort aims to hold back water to slow ‘flashy’ Minn. rivers
Unlike this year, Minnesota often has had to contend with high water. Scientists attribute flash flows to more intense rain events and the loss of wetlands that act as natural sponges. New state funding aims to help landowners store more water on their land.
72% of Minnesota is now in severe drought
The hot, mostly dry conditions forecast through the end of July provide no relief to the dire situation. Water levels are low in many lakes and rivers throughout Minnesota, including at Minnehaha Falls in Minneapolis.
Low water makes it harder to play on Minnesota lakes
Going to the lake is a time-honored summer tradition in Minnesota. But this summer, low water on some Minnesota lakes makes launching watercraft more of a challenge than usual.
Drought stresses Minnesota crops, streams and lawns
Farmers in parts of the state are watching crops shrivel in the heat, and homeowners consider whether to keep their lawns green.
Court sends PolyMet permit back to state environmental regulators
A state court on Monday sent a key air emissions permit for the planned PolyMet mine back to the Minnesota Pollution Control Agency, a setback in the company’s bid to open the state’s first copper-nickel mine.
