Curious neighbors gather to see how native prairie buffers are being used at Lake Delhi, on the Maquoketa River, to reduce erosion, filter pollutants and add natural beauty.

The Maquoketa River WMA formed in 2017 with 34 member cities, counties and SWCDs. The watershed spans nine counties and includes just over a million acres. In collaboration with the University of Iowa and Iowa DNR, planning and public affairs graduate students are working with us to complete the final version of our watershed management plan. Within the watershed, we’re working with communities to address water concerns and demonstrate best practices for soil health and reducing erosion. We’re excited about what the future holds for the WMA!
