Colebrook River Lake through the year
The band is the lake's own normal: where the level has run on each calendar day, 1997–2026. The summer drawdown — and how this year sits in it — shows up without reading a single number.
This year vs the years that matter
This year's trace against last year and the driest and wettest years on record — the drought-context question every lake regular asks.

Full pool, datum, and the gauge
"Full pool" here means the conservation pool — the level the lake is designed to hold for water supply and recreation, not the flood-control space above it. The full explainer covers flood pool and dead pool too.
| Full pool | 710.00 ft NGVD29 · per USACE New England District (Colebrook River Dam) full-pool reference |
|---|---|
| Gauge | USACE series CRD.Elev-Pool.Inst.15Minutes.0.DCP-rev · U.S. Army Corps of Engineers Access to Water data |
| Datum | NGVD29 — The top of the normal pool is 710 ft and flood storage starts at 708 ft, so a summer drawdown on this lake shows up as a long way below full pool. |

LakeDates reports lake level, not ramp status. Whether a given ramp or marina is usable at this level varies ramp by ramp — call the marina before you tow.
