Union Lake is a reservoir in Michigan, near Oakland County.
Stocking records show that the following fish or strains were stocked here. A historical stocking does not by itself prove that a self-sustaining population remains today.
If you are getting ready to fish Union Lake, keep the first plan simple. This reservoir is in Oakland County. It covers about 468.8 acres. The deepest recorded spot is 110 feet. On a first trip, I would use the wind, water color, visible cover, and any signs of bait to decide where to spend time on Union Lake.
The most attractive shoreline is not always the best structure in an impoundment. Drowned channels, submerged roadbeds, points, and places where current brushes cover deserve the first careful casts.
In spring, check warming flats beside a quick depth change. During summer, fish the hours and depths with the best temperature and oxygen. In fall, follow bait as cooling water makes more of the lake comfortable again.
Give every promising area a fair test, but not an endless one. A few casts along the edge, through the cover, and off the break should reveal whether fish, forage, or useful habitat are actually there.

A lake-specific profile for Union Lake in Oakland County reports a fisheries survey from 2025 and vegetation coverage around 0.6 percent. That combination gives us a more useful picture than the lake name alone: it is a mapped basin with both biological sampling and measured plant habitat.
The current record for Union Lake in Oakland County lists Barred Fantail Darter, Black Crappie, Blackchin Shiner, Bluegill, Bluntnose Minnow, Brindled Madtom, Brook Silverside, Brown Bullhead, Central Mudminnow, Cisco, Common Shiner, and Green Sunfish, along with 15 additional recorded species. That is a starting point, not a promise that every species is common in every season or every part of the basin. For largemouth bass, compare shallow cover with the first firm edge before assuming the fish moved deep. Smallmouth bass make rock, harder bottom, windblown points, and offshore edges worth extra time. A small jig is a clean way to locate the active panfish depth. Stocking is kept separate from present-day abundance: the record lists Brown Trout, Lake Trout, Rainbow Trout, Redear Sunfish, Splake, and Walleye. A release confirms fish were placed here, not that they survived, reproduced, or remain common today.
Match hook size, line strength, and lure profile to the fish actually recorded here. If you release a catch, keep it wet, support its body, and limit handling time. Never move live fish or bait from one water to another.
If the same approach fails in several good-looking places, stop repeating it. Change the depth first, then presentation speed, and finally the lure profile until the fish give a clearer answer.
Use the first hour to identify the productive depth. Once that level becomes clear, look for several pieces of structure that intersect it.
If Union Lake is not showing bait, bites, followers, or healthy cover after a fair try, change depth or move to a different type of water. Do not stay put only because the spot looks good.
Review current Michigan fishing rules, weather, water temperature, and water level. Those details can change, so verify them directly instead of trusting an old report.
