I live north of the metro in East Bethel so not to familiar with south metro lakes. Minnetonka, Prior, Medicine, seem to have some popularity. On the north side the Chisago City area Green, Chisago, Lindstrom, Center, and Comfort are usually productive for pan fish, northern, walleye and summer bass. Big Marine also holds some nice crappie to 14" and larger Sunfish. Forest Lake and a bit west Coon lake also holds a variety.
Last year I did a fairly extensive look at DNR lake surveys within a 3 hour drive north of the metro and came up with this list that looked promising for Walleye. I have fished a few during summer, but not all, with fair success. Here is the list. This is typically what you will find on the DNR Lake Finder site only their survey will be for all species. I just took the walleye info. The Navionics link BringAnExtension listed should give you great contours for any of the lakes your interested in.
Scored a lowrance Elite 5Hdi today for $169.99 (awesome sale). Plan to use this on ice and in boat for GPS purposes. Paired with the navionics app, excited to compare accuracy side x side.
If interested in the sale, it's at a store that rhymes with meander fountain..
This is an upgrade for me, I have used the app with good success. Hoping this new unit will be a bit more accurate.
