Water quality standards violations are common during the low flow periods of summer. Runoff from livestock operations appear to be the major problem, followed by treated municipal sewage discharges and urban runoff. Major water uses include fishing and livestock watering. The city of Hartselle discontinued use of Flint Creek as a water supply in 1993. Groundwater is used as a water supply for about 5 percent of the watershed population.
Tests show that about half of the wells are contaminated with coliform bacteria.
A fish health assessment study conducted in the fall of 1993 revealed very low numbers and varieties of fish and poor health conditions. This was one of the worst fishery health conditions observed in the Tennessee Valley. Other cooperators have worked under contract through 319 grants, or have provided support through their normal program activities.
