An Automated Hydrologic Threshold Alert System for the Umpqua River Basin, OR Holly C. Hartmann, Department of Hydrology and Water Resources, University of Arizona, Tucson, AZ Robin Hartmann, The North Umpqua Foundation, Roseburg, OR
The Place: Umpqua River “From the Crest to the Coast”
1951: 31 miles flyfishing only 1988: 33.8 miles Wild and Scenic 1997: Tributaries closed to all fishing due to coho listing
The Hydropower Project 1945-1956 8 headwater dams, penstocks, canals Relicensing Process 1992-2004 Instream flows Eliminate ramping
Ramping: Increasing and decreasing flows to maximize power production Ramping: Juvenile salmonids strand on ledgerock and thousands die
Powerhouse shut-down, bypass valve malfunction, alarm system failure, operator oversight Flows: 904 cfs 338 cfs in 1 hr
Reporting delay and over-correction of flows resulted in difficulty assessing the damage. Cost: $250K+
Goals: • A tool to PUSH information • Real time reporting • Quicker response and assessment • Empower agencies and community: credibility and effectiveness
Stakeholder driven research to assess utility of modern forecasts, and information CLIMAS Research advances in satellite based detection of snow and precipitation Synergy Adoption RESAC/EOS HyDIS Advances in GIS, internet mapping, data management & visualization UA-HWR: User-Driven Hydroclimatic R&D User driven product development User driven application development Synergy between researchers and users
Automated Hydrology Threshold Alert System Part 1 -- Alert Detection and Notification • Obtain real-time data • Test against thresholds • Notify individuals: email, cell phone Clarify thresholds Alert Levels Yellow = Hiccup Orange = Heartburn Red = Heart Attack
Automated Hydrology Threshold Alert System Part 1 -- Alert Detection and Notification • Obtain real-time data • Test against thresholds • Notify individuals: email, cell phone Clarify thresholds Part 2 – Respond, Report, Review: Interactive Website • Summarize threshold exceedance events: ‘Live Forms’ • Community assessment of event, cause, impacts: ‘Live Forms’ • Archive stable ‘.pdf’ reports for annual review
Project ImplementationStakeholder Process Meeting One: Information and Interest • Proposal presentation • Indication of stakeholder support
Project ImplementationStakeholder Process Meeting One: Information and Interest • Proposal presentation • Indication of stakeholder support
Project ImplementationStakeholder Process Meeting One: Information and Interest • Proposal presentation • Indication of stakeholder support Meeting Two: Agency Reps Meeting Three: Conservation Groups • Anticipated conflicts, opportunities? • Which gauges, scope? • Use of end products? • Meaningful report info?
Project Implementation Meeting Four: Reach Agreement on Alert Specifics • Focus on mathematical representation of thresholds in hydropower license • Allowed PacifiCorp operators to be heard on natural flows and the challenge of predicting them. Meeting Five: Refine Alerts after Trial Run • Review alert language, event report design • Adjust frequency of alerts, duration of alert period • Design monthly summaries, web pages, web forms
