Description During 2003-2005, a monitoring study was conducted to determine the effectiveness of Total Maximum Daily Load (TMDL) clean-up efforts in the lower Snoqualmie River basin. Results show that bacteria levels have improved at most sites, but more effort is needed to meet water quality standards. Dissolved oxygen levels in the mainstem Snoqualmie have generally remained the same. More study is needed to determine if dissolved oxygen TMDL targets are met during the August-October critical period. Report recommendations include (1) specific studies to determine sources of water pollution, and (2) additional pollution-control actions.
