Figure Overall Project
Team AssessmentA
Chloride by flow(Cl not frommodels)
Inconclusive (nowinter data) As the field data used to develop this figure do not include sampconclusions regarding chloride from this figure.
Dissolved oxygenby flow
Good Note the slight decline in the concentration of dissolved oxygencombination of decreased water agitation and higher temperaturwarm summer months).
Fecal coliform byflow
Moderate to Poor Generally, a pollutant that is present at high concentrations durin(fecal coliform, in this case) is attributed primarily to non-point years) would only contribute during the high flows when substa
period with the highest flows, fecal coliform counts exceed the the standard is met more than 75% of the time. This would be thswimming, wading, etc.), although the amount of water in the st
Phosphorus byflow
Moderate to Poor Concentrations of phosphorus are greatest at high and low flowparticularly noticeable during low flows as well as non-point loasuspended sediment).
Suspended solidsby flow
Very Good toGood
The concentrations of suspended solids increase with increased The suspended solids may come from runoff that carries a sedimstream sediments.
