Miscellaneous edits

Added drinking water source

From what I understand, special districts, such as forest preserve districts, are not legally part of the county government—though in the case of the FPDCC, the county board serves ex officio as the district's board

Added fixme; deleted ownership tag (special districts, such as forest preserve district, are not legally part of the county government—though in the case of the FPDCC, the county board serves ex officio as the district's board—from what I understand)

Minor correction

I'm fairly certain that Kankakee River State Park (and most/all other Illinois State Parks) fits OSM's criteria for "nature reserve", and not "park". National and state parks tend to be significantly different in concept from "regular" parks.
