Most people have no idea that Iowa has so many aquifers right under the ground we call home. The residents of Belle Plaine had no idea what they were getting themselves into when they decided to drill a well in 1886.
The Belle Plaine Channel caused a disturbance in 1886 when the city of Belle Plaine tried to drill a new well to access it for fire protection.

As the town grew, the need for a dependable supply of clean water grew, as well. The city of Belle Plaine decided to drill a new well. Over 130 years ago, the Belle Plaine Channel let the residents of the small town know just how powerful it was. During the 1880s, people in Benton County, just north of Belle Plaine, encountered gravel and sand aquifers at 300 feet below the surface. We've since learned that the aquifer fills huge portions of an ancient river valley, covered by impervious glacial tills. The tills seal the aquifer and create an amazing amount of pressure.
The town's residents nicknamed the well, "Jumbo." Even after two weeks, it was still putting out over 2,000 gallons of water per minute. The well was finally brought under control after 130 barrels of cement, 40 carloads of stone, and hundreds of feet of 18-inch pipe were installed to stop it.

The reporters' accounts of the events in Belle Plaine during 1886 were sensational, and the modern world named Jumbo The Eighth Wonder Of The World.
They wanted to understand the current situation underground and find out if the underground river was still as violent as it was in 1886. They ultimately decided to recap the site without looking too closely, for fear of a repeat performance from Jumbo.

If you stop by, local self-appointed tour guides may tell you that they study Jumbo in school, even 130+ years after the amazing underground river spewed for 13 months straight.
Residents don't live in fear that they'll get to see Jumbo wreck their modern-day town. There aren't any rumblings from below, and everyone seems to know better than to go around randomly drilling wells in this area.
Are there any other catastrophic well-drilling incidents in Iowa’s history that prove the power of our underground rivers? Let us know in the comments.
