The drought gripping this part of the Piedmont collapsed almost overnight. Since early June the area had been locked in extreme to exceptional drought, with the most severe category holding at nearly 96 percent coverage for four straight weeks running. As late as this past July the area remained entirely in moderate drought or worse, with over 80 percent of it classified severe or extreme. Then, in a single reporting week, the severe-and-worse categories dropped to zero and moderate drought coverage fell to under 18 percent.
The stream gauges tell the same story with more precision. Flow across the Triassic Basins watershed, from Goose Creek to Third Fork Creek to the Eno River, had been crawling along at a fraction of a cubic foot per second for most of the past ninety days. The most recent reading hit 14.7 cubic feet per second, the highest of the entire record, arriving in exactly the week the drought maps broke. That pattern, a flat and starved baseline followed by a sudden spike, is the signature of a sharp storm ending a long dry spell, not a water table recovering gradually from below.
What that first flush carries downstream is worth watching closely. Third Fork Creek, Ellerbe Creek, and Little Lick Creek, all now running with this new pulse of water, are already listed as impaired under the Clean Water Act. Months of low, warm, oxygen-poor flow tend to let fine sediment and adsorbed pollutants settle quietly into the streambed; a first-flush surge like this one is exactly the kind of event that can scour that material back into suspension, dropping oxygen and clouding the water even without any new source of contamination. Of the eleven permitted dischargers in the watershed, one currently has a flagged violation of its permit limits, though none have risen to the level of formal significant non-compliance, so there's no single clear culprit pointed to by the compliance record \u2014 but the hydrology alone makes the next few weeks here worth a closer look.
