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.

Tidal station water level rises above prediction

October 21, 2026

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. 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.
