A sharp, clear morning turning into a bright day, with a soft NNW wind and pressure leaking away. The productive water at Spies Lake will be around reed fringes and open pockets. The productive run goes night into morning. Start on the obvious water and expand from there. Fish follow the bait in autumn, so find one to find the other.

Spies Lake is a Marinette County water, Wisconsin side. The water sits 863 feet up. Around 29 acres of surface means several distinct areas to work. It is low-lying compared with other Wisconsin water we list. The nearest town is Niagara, 26 miles away. Green Bay is the closest city, 61 miles away. Close by you also have: Butterfly Lake 0.6 miles, Jug Lake lies 0.7 miles on, Silver Lake 2.4 miles, Morgan Lake lies 2.7 miles on and Lily Lake 2.7 miles. The nearest boundary is a fair way off.
The records we hold are silent on depth, so plan to find it yourself. The shallow end warms first and pulls fish in ahead of the rest. On a natural lake the weed line and the shelf beyond it do the work. Records held for Marinette County cover brown trout, rainbow trout, largemouth bass and bluegill. The county figures include rivers and lakes alike. Spies Lake fishes better once you know its edges.
Averages move between 13°F in January and 68°F in July. A solid cap is the normal state through winter. Break-up comes around mid April, and the run that follows is short and strong. Averages place the thaw at mid April and the freeze at early December. The middle of summer slows a little, with dawn and dusk carrying it. That shapes the year on Spies Lake.
Access is not recorded for this water. Mapping shows an empty shoreline: no ramp, no jetty, no marked entry. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Read any posted signs at the access point rather than assuming. Some stretches are reserved and marked as such on the ground. Butterfly Lake at 0.6 miles is the sensible second choice. Treat access at Spies Lake as something to verify.
