💧 Reservoir Info Background

Straight from the source — NYC DEP

Cannonsville and Pepacton control flow on the West and East Branch. Live data straight from DEP.

Levels & Capacity nyc.gov ↗ Release Rates nyc.gov ↗

Cannonsville → West Branch · Pepacton → East Branch · Main Stem gets both · Beaverkill & Willowemoc are freestone, unaffected

When reservoirs are near capacity, DEP releases cold bottom water ahead of a spill — good for trout, but flow can rise with no rain in sight.
