Abstract
This report summarizes a technical basis for maintaining a tidal instream flow standard based on a principle of (a) minimum depth of flow for fishery habitat and (b) attenuation of chlorides. The proposal is to replace the existing 7Q10 flow rate standard as required by the DRBC with a 7Q10 flow depth equivalent to protect fishery habitat and chloride standards to address water quality concerns. The current 7Q10 flow rate standard is difficult to measure due to the two – way tidal nature of the White Clay Creek.
