Understanding Dutchess County’s Water

Drinking Water Quality Overview

EPA SDWIS

Dutchess County's water systems carry a failing grade, scoring 39.8 out of 100. Over the past five years, EPA SDWIS records 65 health-based violations — a pattern that public water utilities are required to disclose and correct.

River & Streamflow Status

USGS NWIS

USGS NWIS gauge data (as of 2026-05-14T14:15:00.000-04:00) puts TENMILE RIVER at 271.0 cfs — running somewhat below its historical average at 84% of mean. Streamflow is a leading indicator of drought stress, sediment load, and dilution capacity: low flows concentrate pollutants and warm water temperatures, stressing aquatic life and, in surface-water-dependent systems, the source water quality for treatment plants.

Monitoring Network

EPA WQP

EPA's Water Quality Portal (WQP) aggregates monitoring data from federal, state, and tribal agencies. Dutchess County has moderate coverage with 22 active monitoring sites with 14,255 recent measurements on record. Predominant monitoring categories include organics, pesticide and physical. More monitoring sites generally indicate greater scientific attention to local water conditions — and provide the baseline data that regulators use to set future impairment listings.
