Data Used to Assess Water Quality: | The U.S. Bureau of Land Management sampled Alaska Canyon Creek in August 2002. Fecal coliform bacteria were determined in two samples with concentrations of 3 and 30 colonies per 100 mL, respectively. The second sample exceeded the limit in the objective.

Water Quality Objective/Criterion: | The Lahontan Basin Plan's objective for coliform bacteria states:
"Waters shall not contain concentrations of coliform organisms attributable to anthropogenic sources, including human and livestock waste. The fecal coliform concentration during any 30-day period shall not exceed a log mean of 20/100 ml, nor shall more than 10 percent of all samples collected during any 30-day period exceed 40/100 ml. The log mean shall ideally be based on a minimum of not less than five samples collected a evenly spaced as practicable during any 30-day period. However, a log mean concentration exceeding 20/100 ml for any 30-day period shall indicate violation of this objective even if fewer than five samples were collected." |
