Palmer/Long/Sturgeon/St. Joe
Palmer Lake is right in the Town of Colon (Magic Capitol of the World) Michigan. It connects to another Lake (Long) via a channel. Palmer empties into the St. Joe river but there is a dam so you cannot get to the river from the lake by boat. There are two DNR boat launches on Palmer both good launches. Below the dam is Sturgeon lake & it is the lake that is connected directly to the St. Joe river. Good Walleye & Smallmouth & a few Crappies too. Sturgeon & Long each have a DNR launch as well.
I've fished all three lakes many times in the past 30 plus years. Not known as crappie lakes but do have a few. Much better Bass & Bluegill fishing. They have also been stocked with Walleye for the past several years so there are some Walleye being caught as well especially on Sturgeon/river. All three also have some respectable sized Catfish & Northern Pike in them too.
Hope this helps.
