http://www.wisconsinaquaculture.com/Search_For_WAA_Members.cfm I have had places in Rhinelander, Adams, and also owned "grass lake" near Crandon currently trying to get a pond fishable in the Adams area...seems there are no fish now but apparently had fish at one time or another. That dark water might be stain from the pine trees and to a certain extent it helps keep algae down.
Just bought a aerator from keystone the 1/4 HP model and needed almost 250 feet of line but it really is boiling the water. Like you I cant get up to our spot very often but manage about once a month for a couple of days. Our goals are similiar but I am going to go with perch and bass maybe a few BG. My pond only 7-8 foot deep so intend to have a small energy type aerator for an open area in the cold winters
