Understanding Garfield County’s Water

Drinking Water Quality Overview

EPA SDWIS

Garfield County's water systems carry a failing grade, scoring 29.2 out of 100. Over the past five years, EPA SDWIS records 44 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 2026-05-14T14:00:00.000-05:00) puts Skeleton Creek at 3.0 cfs — well below its long-term average at 9% of mean — low-flow conditions worth noting for water-dependent ecosystems. 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. Garfield County has limited coverage with 2 active monitoring sites with 2,085 recent measurements on record. Predominant monitoring categories include not assigned 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.
