Analysis
Dissolved oxygenby flow
Good Note the decline in dissolved oxygen concentrations at low flows. This is likely due to a combination of decreased wateragitation and higher temperatures (low flow conditions are often associated with the warm summer months).
Fecal coliform by
flow
Moderate to Poor Generally, a pollutant that is present at high concentrations during high flows and low concentrations during low flows(fecal coliform, in this case) is attributed primarily to non-point sources. Note that during periods with the highest flows,
fecal coliform counts exceed the regulatory standard nearly all of the time. During low flows, the standard is met
consistently. This would be the safest time for any recreational uses (boating, swimming, wading, etc.), although the
amount of water in the stream may limit recreational use to wading.
Phosphorus by
flow
Good Concentrations of phosphorus are greatest at high flows. This suggests the dominance of non-point sources ofphosphorus. Note also that the minimum concentration increases at low flows, possibly due to background phosphorus
sources such as non-contact cooling water.Suspended solids
by flow
Good The concentrations of suspended solids increase with increased flows, suggesting contributions from non-point sources.The suspended solids may come from runoff that carries a sediment load, from stream bank erosion, or re-suspended
stream sediments.
