Notes
King County Department of Natural Resources review comments on the Port of Seattle’s July 2001 Low Flow Impact Analysis and Flow Impact Offset Facility Proposal. The review evaluates HSPF hydrologic modeling, impact assessments, and conceptual designs for reserve storage facilities intended to mitigate low flow impacts in Des Moines Creek, Miller Creek, and Walker Creek basins. The reviewer identifies gaps in documentation, raises biological concerns about early summer flow reductions affecting salmonids, and recommends monitoring programs for stream biology and water quality.
