2001-07-09EXH AR020456: Draft Meeting Notes – Low Flow Analysis, STIA Third Runway 401 Permit, July 9, 2001
These draft meeting notes from a July 9, 2001 technical meeting cover low flow analysis related to the 401 Permit decision-making process for Sea-Tac International Airport's Third Runway project. Attendees from the Department of Ecology, King County, Port of Seattle, and several consulting firms discussed methods for determining low stream flow impacts and mitigation requirements across affected watersheds. Key topics included biological effects on fish habitat, a proposed 0.1 cfs mitigation flow for the Des Moines Watershed, and the use of 2-year 7-day low flow rates to guide mitigation planning. -

2001-07-02EXH AR023805: Email Chain – Non-Hydrologic Effects Water Rights Relinquishments & Summer Low Flow Analysis
In a July 2, 2001 email chain, Kelly Whiting of Metro King County raises concerns about the analysis of 'non-hydrologic' effects related to water rights relinquishments and their impact on summer low flows in a Sammamish River watershed study. Whiting questions the assumptions made about non-respondents to a water withdrawal survey, arguing that the rates assigned to them appear disproportionately high compared to trends shown by actual survey respondents. The email requests a walkthrough during an upcoming Thursday meeting to clarify how these figures would be incorporated into a low-flow mitigation plan. -
2001-07-02EXH AR023807: Email Whiting to Kenny — Ecological Input Stream Hydrology Mitigation
A July 2001 email from King County engineer Kelly Whiting summarizes ecological recommendations regarding proposed stream flow mitigation measures. A lead stream ecologist advised that mitigation plans be compared against existing stream hydrology to avoid abrupt changes that could disrupt biological processes, such as sudden summer flow increases confusing fish behavior. The ecologist also emphasized that water quality factors like temperature and dissolved oxygen are as important as flow rates, and suggested introducing reserved water gradually through ponds or wetlands rather than directly into streams. -

2001-06-14EXH 303: Draft Meeting Notes — Low Flow Analysis, STIA Third Runway 401 Permit, Jun 14, 2001
These draft meeting notes from a June 14, 2001 technical meeting cover the low flow stream analysis conducted as part of the 401 Permit Decision-Making process for Sea-Tac International Airport's Third Runway project. Attendees from the Department of Ecology, King County, Port of Seattle, and consulting firms identified five additional technical tasks, including verifying groundwater basin calibration parameters for Walker Creek and Des Moines Creek, documenting embankment infiltration rationale, and assessing water availability for proposed low stream flow mitigation measures.
