Lake Erie walleye in full swing; Grand River running 6,890 cfs post-flood

What's Biting

What's Next

The Grand River's current flow of 6,890 cfs (USGS gauge 04119000) is elevated but trending in the right direction after the severe mid-April flood pulse documented by MI DNR. As the river drops toward more typical late-spring levels, shoreline access and wading positions will open progressively through the first week of May. Walleye and any holdover steelhead will be stacked in slower tailwater seams, inside bends, and behind mid-channel structure where the current deflects — those are the spots to prioritize while flows remain brisk.

On Lake Erie, the post-spawn walleye pattern that carried Tomasek to the NWT opener title is still fully active, per Outdoor Hub. Post-spawn fish typically scatter to reef edges, rocky transition zones, and hard-bottom structure in the 15-to-30-foot range and feed aggressively through early May before staging deeper as surface temps climb. On The Water's conversation with Captain Joe Fonzi reinforces that goby-driven forage has elevated average Erie walleye size — matching goby color profiles and profile in jigging presentations has been a productive approach this season.

The Full Moon on May 1 compresses the most reliable feeding into the first and last 90 minutes of daylight. Midday activity across both the river and lake fisheries will be slower. On rivers like the Grand, full-moon phases also correlate with increased walleye movement into shallower feeding lies after dark — low-light hours are worth the commitment if conditions allow.

Smallmouth bass should be approaching pre-spawn staging on both Lake Erie and Lake Huron through this weekend. Captain Fonzi's Lake Erie discussion on On The Water points to quality fish on rocky transition structure; look for bass holding on points and gravel-to-rock transitions in 6 to 15 feet of water. A jerkbait or tube on light line is the classic pre-spawn approach. Note that Michigan's statewide bass season opener typically falls in late May — check current MI DNR regulations before harvesting.

For the weekend, target Grand River walleye at first and last light when the combination of dropping flow and moonrise creates optimal conditions. If the river continues its downward trend, mid-week could open additional wade-fishing access that has been underwater since April.

Context

Early May is a genuine hinge point for Michigan freshwater fishing — several major transitions are happening simultaneously. Steelhead runs on rivers like the Grand typically peak in late March through April and wind down through May; by the first week of May, the main push is usually past its prime, with darker holdover fish the primary quarry. This season's extended high water, flagged by MI DNR as severe flooding through mid-April, likely compressed the peak window and moved fish through faster than normal, leaving fewer in the system now as flows recede.

Walleye across the Great Lakes typically complete spawning from late March through mid-April, meaning post-spawn fish are now dispersing and feeding aggressively — the NWT tournament results on Erie confirm that pattern is running on or slightly ahead of schedule. In the Grand River corridor, walleye historically stage in the lower river reaches through spring before dispersing to summer habitat; at 6,890 cfs, fish will favor deeper slower water and won't be accessible in typical wading spots yet.

For Lake Huron, Great Lakes Now reported that a newly restored reef at Channel Island in Saginaw Bay was completed last October, adding nearshore spawning structure intended to support native fish populations. This spring is the first full season with that structure in place — it is worth watching as a productive early-season spot for walleye and perch anglers targeting Saginaw Bay.

No direct comparative data in the current intel feeds allows a precise early-versus-late assessment for 2026 overall, but the mid-April flooding documented by MI DNR almost certainly slowed river-system warming by several days relative to a dry spring. Lake Erie surface temperatures appear to be tracking near seasonal norms based on the active walleye tournament bite. Overall, conditions are playing out close to a typical early-May Michigan pattern — river access constrained by runoff, Great Lakes species transitioning post-spawn, and bass season building toward its late-May opener.
