| Study QA Project Plan Description | Cherry and Ames Creeks are not on the federal Clean Water Act Section 303(d) list for dissolved oxygen (DO). Low DO conditions have been documented during varying temperature and discharge conditions. This suggests an independent mechanism may drive this condition, and emphasizes the need to understand the physical, biological, and hydraulic properties that affect DO in the flood plain. Seasonal depletion of DO in the flood plain habitats of Cherry Valley is at times severe enough to kill fish or otherwise make those habitats inhospitable. It is critical to understand what causes the depletion if it is to be addressed. Identifying the mechanism behind the impaired DO conditions is paramount to protecting important salmon rearing and migration corridors in the lower Snoqualmie River watershed. |
