Overview of findings
according to the Idaho water quality standards:Idaho water quality standards
"Dissolved Oxygen Concentrations must exceed six (6) mg/l at all times" (p. 151)
So at Mr. Vaughan's, the dissolved oxygen levels were not enough.
Phosphate levels were also a problem throughout the river.
Important bugs - stoneflies, caddisflies, and mayflies - were present up by Daniels but not down at Mr. Vaughan's or at Mr. Palmer's. This indicates pollution.
Turbidity was a problem at Mr. Vaughan's and Mr. Palmer's.
