Streams still running low weeks after the drought "ended"

August 10, 2026

Streamflow gauges across the Loamy High Lime Till Plains are still reading well below the recent seasonal average this week (August 4-10) - at Fall Creek at Millersville, the latest reading was 7.23 ft3/s against a 90-day average of 230 ft3/s - even though the county's drought was officially declared over back in spring 2026. That gap between the paperwork and the water itself is worth watching. A multi-month drought built through last fall and was technically cleared months ago, but soils and stream baseflow don't reset the moment a monitor lifts a designation; recharge lags behind rainfall, especially once the evapotranspiration demand of August heat sets in.

That means the streams and the ground around them are heading into peak summer stress already carrying a deficit, with less water in reserve than a normal late-summer week would offer. For the native forb stands and specialist insects reported here in July, this matters less as a direct threat than as a thinner margin: a dry spell or hot stretch that a fully recovered system might absorb without strain now lands on ground that hasn't finished catching up.

Against that backdrop of reduced baseflow, wastewater discharge quality carries more weight than it would in a wetter year, since there's less clean water available to dilute it. The BELMONT & SOUTHPORT ADVANCED WASTEWATER TREATMENT PLANTS have an open permit violation on record, though no parameter-level details on the discharge itself were available this session. A stressed, low-flow stream is generally a condition under which effluent problems have less capacity to be diluted, but we don't have data here confirming what, if anything, this facility is currently discharging or what effect it's having downstream - that's a gap worth watching rather than a conclusion to draw yet.

None of this is catastrophic on its own, but it stacks: a slow hydrological recovery, a summer heat load, and a permitted discharger out of compliance are converging on the same stretch of the plains at the same time. Watching how the till plains' streams and their associated prairie remnants fare through the rest of August will say a good deal about how much resilience is actually left in the system versus how much is being assumed because a drought declaration expired.

Eagle Creek Reservoir faces convergence of compliance and algal risks

July 14, 2026

Eagle Creek Reservoir, the city's primary drinking-water source, carries a federal impairment listing — the only water body among 34 nearby systems requiring a formal cleanup plan. This designation reflects years of mounting pressure that converge most acutely during summer heat.Two major wastewater treatment plants serving the area remain in permit non-compliance, continuing to discharge nutrients into a system already stressed by seasonal heating. July is peak season for toxic algal blooms — the conditions that threaten both ecosystem health and public safety are now fully aligned.

Northern catalpa draws summer insects

June 6, 2026

The air around the northern catalpa carries the weight of summer heat and the faint sweetness of its late-season blooms. These threatened trees stand scattered through Indianapolis's neighborhoods, their broad heart-shaped leaves casting wide pools of shade. If you are walking beneath one now, look up through the canopy for clusters of white flowers marked with purple and yellow spots, each bloom shaped like a small trumpet opening to the longest days of the year.The northern catalpa times its flowering to coincide with peak insect activity. While most trees finished blooming weeks ago, catalpa waits until deep summer when the breeding season reaches its height. Each flower cluster holds dozens of individual blooms, each one producing nectar accessible to insects with varying tongue lengths. The flowers open in sequence over several weeks, extending the feast through July's heat when other nectar sources have dried up or gone to seed.This timing draws the Eastern Eyed Click Beetle and dozens of other insects to the catalpa's crown. The click beetle, with its distinctive white eyespots on a black thorax, visits the flowers for nectar but also hunts smaller insects attracted to the same blooms. Catalpa flowers pull in everything from tiny sweat bees to large carpenter bees, from hover flies to butterflies. The tree becomes a temporary feeding station where predators and pollinators share the same branches. Beetles browse the flower clusters while bees work individual blooms just inches away. The catalpa's extended flowering period supports multiple generations of insects through the peak breeding season, when females need extra energy for egg production and males compete for territory.The relationship extends beyond the flowers. Catalpa leaves feed the larvae of the catalpa sphinx moth, which appears nowhere else in the ecosystem. Adult sphinx moths emerge in waves throughout summer, their thick bodies and rapid wingbeats making them important pollinators for evening-blooming plants. The tree's broad leaves also shelter jumping spiders like the Dimorphic Jumping Spider, which hunts the smaller insects that gather on the leaf surfaces. When catalpa pods form in late summer, they provide winter shelter for overwintering insects, extending the tree's support through the cold months.The white trumpet flowers catch the afternoon light filtering through the broad leaves above. Each bloom opens for just a few days before dropping its petals, but new ones continue opening in the cluster. Listen for the steady hum of wings around the flowers, the sound of summer's breeding season sustained by this threatened tree's perfectly timed abundance.

Eastern redbud pods harden in late spring

May 22, 2026

The air carries the green weight of full leaves at Virginia Fairbanks Art & Nature Park, where late May has settled into the steady work of growth. Eastern redbuds stand among the maples and oaks, their heart-shaped leaves now broad and darkening, no longer the tender yellow-green of early spring. The showy magenta flowers that lined their branches in March are gone, replaced by something quieter but no less purposeful.Flat brown pods hang in clusters from the redbud branches, each one the length of a thumb and narrow as a coin. These are the tree's next generation, packaged in papery cases that rustle when the wind moves through them. The pods developed from the flowers' ovaries, swelling through April as the tree poured resources into seed production. Now they hang like small leather purses, their surfaces beginning to harden and their edges starting to curl.Inside each pod, four to eight seeds lie flat against the walls, dark brown and kidney-shaped. The redbud has invested heavily in this moment. Unlike many trees that scatter thousands of tiny seeds, redbuds produce fewer, larger seeds with substantial food reserves. Each seed carries enough stored energy to send a taproot deep into the soil and unfurl its first pair of rounded leaves before it must begin photosynthesis. The pods protect this investment, their tough walls keeping moisture in and insects out while the seeds complete their development.The timing matters here in central Indiana. Redbuds flower early, before most other trees, when pollinators are scarce but eager. By late May, when the forest canopy has closed and competition for light intensifies, the redbud's work shifts from capture to release. The pods will continue hardening through summer, their walls becoming brittle and their seams weakening. Come autumn, they will split along their edges with small pops, spilling seeds onto the forest floor. Some seeds will germinate the following spring, but many will wait longer, lying dormant in the leaf litter until conditions align just right. This patience serves the species well. Redbud seedlings need gaps in the canopy to establish themselves, and those gaps appear unpredictably when storms topple larger trees or disease opens clearings.The Great Crested Flycatcher calls from somewhere in the canopy above, its voice cutting through the softer sounds of leaves moving against each other. If you are standing beneath a redbud now, run your fingers along one of the hanging pods. Feel how the surface has changed from the soft green of early development to something firmer, more decisive. The tree has made its commitment to the future, and these small brown packages carry it forward into seasons not yet arrived.
