    Team Assessment

    Analysis

    Dissolved oxygenby flow

    Good Note the decline in dissolved oxygen concentrations during low flows. This is likely due to a combination of decreasedwater agitation and higher temperatures (low flow conditions are often associated with 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. The infrequent sewer overflows (once every 2-5

    years) would only contribute during the high flows when substantial non-point loads are already present. Note that during

    any period with the highest flows, fecal coliform counts exceed the regulatory variance standard. During moist conditions,

    the counts are above the variance standard over 50% of the time. During low flows, the variance standard is met all of the

    time. This would be the safest time for any recreational uses (boating, swimming, wading, etc.).

    Phosphorus by

    flow

    Moderate to Poor Concentrations of phosphorus are greatest at high and low flows, although concentrations are frequently greater than the

    planning guideline under all flow conditions. The higher concentrations at flow extremes suggests a background source ofphosphorus that is particularly noticeable at low flows (perhaps due to inputs of non-contact cooling water) as well as non-

    point sources of phosphorus at high flows.

    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.
