Understanding Rooks County’s Water

Drinking Water Quality Overview

EPA SDWIS

Rooks County's water systems carry a failing grade, scoring 2.7 out of 100. Over the past five years, EPA SDWIS records 57 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 2026-05-14T13:30:00.000-05:00) puts SF SOLOMON R at 0.2 cfs — well below its long-term average at 0% 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.
