(Progomphus obscurus) are active at Steele Creek and the Eastland greenway this month — a season when streamflow has dropped to 4.4 cubic feet per second, leaving the watershed at its thinnest midsummer margin. These are among the Piedmont's most faithful stream specialists: their larvae spend years buried in clean, sandy substrate, emerging only where siltation and prolonged low flow haven't yet scoured the streambed bare. Their presence now signals that some stretches of the water are still holding the conditions these insects demand.
The clubtail family has been reading stream health in these sandhills since long before the Catawba people built their towns along the same waterways — and a midsummer pulse at this level is precisely when the ledger gets tested. What persists here tells us about the watershed's true capacity to sustain its most demanding residents.
