Saginaw Bay is 61 degrees. The walleye are feeding up shallow as the water cools, the second run of the year. The Kawkawlin reaches the bay a half mile down the shore, and the Saginaw River up the way is running 170 cfs, dropping. If you make the run up to the AuSable, it is at 905 cfs and 49 degrees, still cold. The local base-50°F heat calculation stands at 2258 degree days against this site's modeled reference of 2518, equivalent to running about 260 days late on that reference curve. This is a model comparison, not a measured date shift for every species. Separately, USA-NPN reports an accumulated-heat anomaly of +325 degree days against its own normal. This source uses a separate reference and is not interchangeable with the local model comparison. Daylight is 10 hours 51 minutes, shortening about 2.9 minutes a day, and the soil at six inches is 52 degrees, warm enough for morels and the warm-season garden. Brook and brown trout are coloring up and moving onto the gravel: the brookies in spawning orange, the browns going buttery gold with crimson spots. It runs with the leaves turning. Fish carefully and give the redds a wide berth. Out at Pinconning, the deer are in the pre-rut, scrapes and rubs opening up. On the bay, 8 notable birds are being reported, including Forster's Tern and White-rumped Sandpiper. Bay County is in abnormally dry on the latest Drought Monitor.
Correlation: First hard frost and Walleye fall feed-up overlap on the calendar right now. Watch whether they track together as the years bank up.
Where the year stands, read from the day's numbers and the calendar. Written each morning, kept as a record. Not a field report.
A waxing gibbous moon hung over the Flats last night, and the sandhill cranes that have been gathering there in their thousands will be restless under it. The season is running a full month behind itself, and the maples along the AuSable are only beginning to consider turning, where by rights they should be past peak. Soil warmth holds at 72 degrees, which keeps woolly bear caterpillars crossing the roads in no hurry. King salmon are pushing up into the river mouths from the bay, and brook trout are due on the spawning gravel in the headwaters. Asters still carry enough color to draw the last bees. Walk the Shiawassee Flats dike road at first light and count the cranes before they lift.

The signals nature is giving right now, and what each one points to on the rivers, in the woods, and in the garden.
All seventy-one events, filed under the month each one peaks in. These are the ordinary dates, the year as it usually runs here. This year is running about 39 days behind normal, so the heat-driven ones are arriving off these dates by about that much. The months are uneven on purpose. May carries fifteen of them and January carries two, which is what the year is actually like here.
The lakes sit at their yearly low and the great horned owls are already on eggs. The first insistence that something has begun while everything looks finished.
Bucks drop their antlers into the snow and the eagles settle onto nests. Nothing is green, but the year has committed itself.
Sap runs in the maples, red-wings come back to the cattails, and the woodcock begins his sky dance at dusk over wet ground. The first month you can hear the change.
Ice leaves the inland lakes, steelhead push up the tributaries, and the Hendricksons come off the AuSable. On the bay the northeast wind season opens.
The crowded month, and the one that rewards attention most. Lilac, morels, warblers, apple blossom, the median last frost, and oak leaves reaching the size of a squirrel's ear.
Fawns in the tall grass, fireflies over the ditches, and the Hex hatch on the AuSable, which is the one night of the year the big trout feed without caution.
The bay comes to its warmest and its calmest, the lakes to their seasonal peak. Basswood in bloom, and the year holding still for a few weeks.
Trico spinners at first light, katydids after dark, and the first goldenrod along the roadsides. The turn begins well before anyone admits it.
Velvet comes off the antlers, the warblers go back south, and the sugar maples show their first color in the crowns.
Peak color through the northeast, the first hard frost on the garden, and trout moving onto the spawning gravel. The walleye feed up for winter.
The rut, the cranes staging, the swans going south. The last of the moving, and then the woods go quiet.
Ice takes the inland lakes, and in some years the snowy owls come down out of the north. The year closes as quietly as it opened.
