Five seasons of area totals.

What MDC published for each managed area, 2021-2022 through 2025-2026. Whole-area numbers only. MDC does not publish blind or pool history, so this is each area as a whole, not a spot within it.

2025-2026 day by day

Every row shares the same dates, so read straight down. Gaps are days MDC did not report, not zero-bird days. Tap a season in the table above to switch.

No river row here: no USGS gauge with daily records is clearly tied to this area's water.

These tables describe past days. They are not a forecast, a small day count means a shaky number, and one thing lining up with another does not mean it caused it. Temperature and wind are from Malden FAA Airport, about 11 miles away, for sunrise to mid-morning on MDC's posted date.
