Science Panel Meetings: Utah Lake Water Quality Study
The Utah Lake Water Quality Study Science Panel is a disciplinary-based panel whose members have scientific expertise relevant to Utah Lake. The Panel identifies data gaps, provides recommendations to the Steering Committee, oversees research activities, and implements a process for independent peer review, among other responsibilities.
Next meeting
Science panel meeting: May 28, 2026 11 a.m. to 1:00 p.m.
