In 2020, Izaak Walton League member Tom Perazella started creating a rain garden full of native flora that would provide food and habitat for wildlife.

In 1924, Will Dilg, the League’s first president, urged chapters along Iowa’s polluted Cedar River to collaborate and present the problem to the state’s Board of Health. Chapters agreed - and won their case.
