Tidal station water level rises above prediction

October 21, 2026

3 views

Water level at the nearby tidal station measured 1.380 m on 2026-10-21 at 15:00, standing 0.296 m above the predicted level for that time.¹ Positive deviations of this magnitude reflect storm surge or extreme tidal forcing; the observed level remains within normal tidal range but signals atmospheric or hydraulic conditions driving water higher than the astronomical prediction.¹

Fall caddisfly emergence signals clean water

October 21, 2026

Multiple caddisfly taxa were observed in early October, including Pycnopsyche antica on 2026-10-10 and (Limnephilidae) on 2026-10-01. These pollution-sensitive insects indicate cool, clean, well-oxygenated water needed for their larvae to develop. Fall emergence of caddisflies at this ecosystem's latitude peaks in October as temperatures drop.

, flagged as Threatened, was observed on 2026-10-14 in Esopus and on 2026-10-01 in New Paltz. Mid-October sightings align with autumn staging behavior as the lungless species prepares for winter dormancy in cool, moist refugia, with activity expected to tail off sharply as soil temperatures drop.
