The purpose of this report is to assess the current state of Kathlyn, Seymour, Tyhee and Round Lakes (the Smithers Lakes) as it relates to designated uses. Water quality objectives were prepared by Boyd et. al. in 1985 for the four Smithers Lakes, and they were updated by the Ministry of Environment, Lands and Parks (MELP) Water Quality Branch in 1996 (Table 4). In this report we present the results of monitoring completed in 2001 and 2002/03 to assess attainment of water quality objectives for the Smithers Lakes. The 2002/03 sampling program was more comprehensive than the 2001 program and this report focuses on 2002/03 data. We include calculation of a Water Quality Index value and ranking for each lake and determine if the water quality objectives are still valid or need to be updated.
