This document consists of a fax transmission from Parametrix, Inc. to Scott Tobiason at the Port of Seattle, dated March 29, 1999, transmitting water quality data logs and flow weighting calculation worksheets for WGR (water quality) samples collected from receiving streams on February 22, 1999. The attached field data logs record measurements such as pH, temperature, dissolved oxygen, and water levels at a site designated 'WC,' along with observations of rain, sheen, and water color during sampling. A flow weighting calculation worksheet for the 'Walker' site summarizes subsample volumes and calculates a total storm flow of 33,030 units for a 30-inch pipe.
