Was reading the wikipedia article on Potato Creek State Park, and can across this excerpt, describing the creation of a reservoir, Worster Lake:
'About a century after the area was converted into farmland (and as many fields were becoming less productive), Darcy Worster began re-creating natural areas, as well as lobbying to dam the creek to create a reservoir for fishing and recreation activities. He often sent hand-crafted insects to "bug" state legislators.'
