Understanding Yalobusha County’s Water

Drinking Water Quality Overview

EPA SDWIS

Yalobusha County's drinking water received a D grade, scoring 47.0 out of 100. Over the past five years, EPA SDWIS records 3 health-based violations — a small cluster that warrants attention.

River & Streamflow Status

USGS NWIS

USGS NWIS gauge data (as of 2024-04-10T13:00:00.000-05:00) puts OTOUCALOFA CREEK CANAL at 3.5k cfs — running significantly above its long-term average at 2047% of mean flow. 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. Yalobusha County has limited coverage with 9 active monitoring sites with 4,152 recent measurements on record. Predominant monitoring categories include physical and organics, other. 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.
