Cyanobacteria bloom emerges as July heat arrives

appeared near Lowell in late June as summer heat began pushing water temperatures into bloom territory. The outbreak is not surprising: of the roughly 50 water bodies in the immediate area, twenty are now impaired by nutrients streaming in from cropland runoff.

What makes this bloom instructive is what's missing from the landscape. The wetlands that once filtered this agricultural drainage were systematically drained beginning in the 1800s, converting water-retentive ground into tillable fields. That historical choice eliminated the natural treatment system that worked at no cost and no maintenance. Current remediation efforts — pond construction, filter strips, in-stream restoration — are now attempting to rebuild, piecemeal, what the original wetland complex once provided freely.

Polyphemus Moth appears at peak midsummer emergence

July 29, 2026

(Antheraea polyphemus) emerged near Clarksville this month — a single sighting on July 9th, right at the peak of the species' fleeting adult flight window. These are among the largest silk moths in North America, with a wingspan of up to about 5.5 inches (14 cm), and are named for the Cyclops of Greek myth, their hindwings marked with pale eyespots that mimic the mythical creature's gaze.Adults emerge mouthless and live only a few days — a brief, frantic window for mating before they vanish. The real work of the species happens in the long caterpillar stage, which spends the summer feeding on oak, maple, birch, and cherry leaves. In midsummer, when the big silk moths are at the peak of their brief season, a single sighting like this one is worth pausing for.

Polyphemus Moths recorded 35 times in 60 days this summer

July 29, 2026

(Antheraea polyphemus) have been turning up steadily since late May — 35 observations across 60 days, from residential streets in Grand Rapids to rural townships near Lansing, with the most recent confirmed sighting at Whistle Stop Park in Byron Center on July 26.These are among the largest silk moths in North America, with wingspans reaching six inches. The large eyespots on their hindwings — giving the species its name from the one-eyed Cyclops of Greek myth — serve as a defense against predators during the adults' brief final days. Adults live only a week, never eat, and exist solely to find a mate.The larvae feed on oaks, maples, birches, and cherries, making the species a tracker of woodlot edges and riparian corridors across a range of settings. That these moths are turning up from urban parks to farm-country woodlots suggests broadleaf tree cover is widely distributed here, though presence records alone don't tell us how well connected those patches are.

Ionia County's dryness spreads from zero to near-total in two weeks

August 13, 2026

Ionia County shifted from completely free of drought conditions to nearly blanketed in abnormal dryness in just two weeks, a pace worth pausing on. Through most of this spring and into late July, the U.S. Drought Monitor showed 0% of the county registering any dryness at all. Then, in the week ending August 3, that jumped to nearly 69%, and by the week ending August 10 it had climbed to over 99% of the county classified as abnormally dry.That's an unusually fast onset, the kind of shift that outpaces the slow, gradual drawdown this landscape typically sees as August wears on. The Lansing Loamy Plain sits within the broader Southern Michigan/Northern Indiana Drift Plains, a mosaic of till plains and moraines where soils generally hold moisture well into summer; a swing this abrupt suggests conditions turned quickly rather than built gradually.For now, none of that dryness has crossed into moderate drought, and that distinction matters. In the week of August 12\u201318 last year, the county wasn't just abnormally dry, it already had nearly 17% of its area in moderate drought or worse. So this year's dry spell arrived faster but hasn't yet deepened the way last year's did by mid-August.No streamflow gauge close enough to this stretch can currently confirm whether the creeks and wetlands here are already running low, so the story right now is about the dryness classification spreading rather than about confirmed low water. Given how quickly it moved, the next few weeks are worth watching closely. Grand River Waterway tracks conditions across this drainage and is a good source to follow as this develops.
