Lake Michigan shoreline in Ottawa County, Mich., is shown on Feb. 1, 2022. Despite its closeness to the lake, the county has areas where household and business wells are running short of water.

Experts say Ottawa County is a cautionary tale for the state of Michigan, which is trying to leverage its water abundance to build a "blue economy" as climate change brings more drought and depleted aquifers to much of the U.S.
