Data and Information Type: | Water column surveys (e.g. fecal coliform) |
Data Used to Assess Water Quality: | The U.S. Bureau of Land Management sampled Dry Creek at three stations on September 23, 2002. Counts of fecal coliform in 3 samples were 1, 39 and 2 colonies per 100 mL.
(Because the objective requires a minimum of five samples in a 30 day period, log means were not calculated.) |
Data Reference: | Water quality data for surface waters on U.S Bureau of Land Management lands in Lassen and Modoc Counties. |
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 wastes. 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 as 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." |
