Fall walleye and smallmouth bite shifts to green weeds and cooling water
Water temperatures across the Twin Cities metro sit in the mid-60s this week. USGS gauges 05289800, 05288580 and 05288705 read 68, 67 and 65°F, while the Mississippi at gauge 05331000 is running 8,150 cfs and gauge 05288500 shows 2,750 cfs. Those readings put fish in a classic fall transition, and the regional intel lines up with it. Fishing the Midwest says the walleye bite turns on as the weather cools, and recommends the plain rig, a bottom bouncer with a plain snell and a nightcrawler, because it keeps catching fish in cooler water. The same outlet says to find living green weeds. As weeds die back and oxygen drops, baitfish and gamefish relocate to the green weeds that remain, so those patches are the first place to look. Their bladed swim jig with a plastic trailer is described as a producer for bass, northern pike and walleye together. Tactical Bassin points to shallow water this month, and says jigs, soft jerkbaits and topwater all play in October. Fish sit near hard structure like dock pilings, laydown trees and rocks. On Lake Superior, the MN DNR Lake Superior Summer Fishing report closed out its season on October 8. Lake trout season ended October 4 and reopens December 1. Salmon, rainbow and brown trout stay open year round in the lake, so check state regs before harvesting.

What's next
Expect the metro stream and river temperatures to keep sliding as nights lengthen. As readings drop from the mid-60s, the shallow weed edges should concentrate more fish, and the walleye bite on bottom-bounced crawlers should improve through the coming days. Smallmouth and pike will likely stay close to remaining green weeds and hard cover while the water holds above the 60s.
The moon is new, so the darkest nights fall this week. Low-light windows at dawn and dusk are usually the best times for walleye, and a slow-rolled bladed jig or a plain rig along weed edges fits those periods well. Midday, tighten up around rock and dock structure and throw jigs or soft jerkbaits, per Tactical Bassin's fall approach.
River flows are steady on the smaller streams (gauges 05289800, 05288580 and 05288705 report roughly 1 to 5 cfs), so expect clear, low water in those spots. Light line and subtle presentations are the safer bet there. The larger Mississippi flow at 8,150 cfs calls for heavier weights to hold bottom.
For anglers heading north, the Lake Superior lake trout closure is now in effect, but rainbow and brown trout stay open on the big lake. Always confirm current rules before keeping fish.
Context
Mid-October is typically the heart of the fall feed in Minnesota. Summer weed beds are collapsing, baitfish are shifting, and walleye, pike and smallmouth start packing on weight ahead of winter. That generally makes this one of the more productive stretches of the year for anglers willing to move until they find green weeds or hard structure.
Water in the mid-60s is on the warm side for the second week of October, so the full turn-over bite may still be ahead. As temperatures fall into the 50s, expect fish to slide deeper and bites to become more concentrated, and the shallow topwater and swim jig pattern to fade in favor of slower jigging with live bait.
