Analysis
Dissolved oxygenby flow
Moderate Note that the largest declines in dissolved oxygen concentrations occur at low flows. This is partly due to a combinationof decreased water agitation and higher temperatures (low flow conditions are often naturally associated with the warmsummer months). Decreases during low-flow conditions may be exacerbated by oxygen demand from organic material
and in-stream biochemical oxygen demand.
Fecal coliform by
flow
Moderate 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 any period with the higher
flows, fecal coliform counts exceed the regulatory standard about 50% of the time. During low flows and dry conditions,
the standard is met well over 75% of the time. This would also be the safest time for any recreational uses (boating,
swimming, wading, etc.), although the amount of water in the stream may limit recreational uses to wading.
Phosphorus by
flow
Very Good to
Good
Concentrations of phosphorus only exceed the planning guideline at higher flows. This suggests that the excess
phosphorus is originating from non-point sources. The similarities between the phosphorus and suspended solids data
suggest that the phosphorus may be associated with suspended sediment.
Suspended solids
by flow
Very 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.
