Rainwater Basin Plains

Kearney County drought coverage dropped from 99.44% in Moderate Drought or worse during mid-August to 0.59% by September 15, driven by August precipitation of 4 in against a normal of 2.9 in. The August rainfall marked relief from a severe dry spell that had persisted through July and into August.

Mean daily temperatures at Minden station (7 km away) have run 2°F above normal for the high and 7°F above normal for the low over the past 30 days, continuing a warm pattern established during the late summer dry period. Nighttime temperatures have been unusually warm for fall.

Purple loosestrife, an introduced plant species, was documented on September 4 at multiple locations near Gibbon and in Kearney. The species continues to persist in the region through late summer, flowering in wetland habitats across the basin where seasonal and temporary flooding support its establishment.

Great Plains Ladies' Tresses, a state-threatened native orchid, was observed flowering near Nebraska on September 19 during its normal late summer to fall blooming period. The species flowers between August and November in calcareous soils of prairies and fens, with above-normal temperatures in the preceding weeks potentially influencing timing.

A Red-headed Woodpecker was recorded on 2026-09-20 at Bassway Strip WMA. This species is flagged by USFWS as a Bird of Conservation Concern rangewide with a breeding season extending to Sep 10, and the species is listed as Near Threatened. Its presence at the tail end of the breeding season reflects broader declines across its range.
