Note 1: All results refer to the number of fecal coliform colonies found in a 100 ml. sample of water. Washington Administrative Codes (WAC) 173-201A, Section 030, establish the standard of 50 colonies per 100 ml of water for Class AA streams, which includes McAleer and Lyon Creeks.
Note 2: The main branch of Lyon Creek experienced sewage contamination, and elevated levels of fecal coliform, in early September 2005 resulting from a pipe break at a pump station in Mountlake Terrace upstream of Lake Forest Park.  Mountlake Terrace officials declared that fecal coliform levels had returned to normal ranges on Lyon Creek several days prior to the collection of the samples reported here. Sample L6 was from a branch of Lyon Creek not effected by the sewage spill.
