US Army Corps of Engineers BUILDING STRONG ® Temperature Target and Evaluation Criteria of the Middle Fork Willamette River Dan Turner Environmental Engineer Portland January 27, 2015

BUILDING STRONG ® PORTLAND DISTRICT 2 Outline  Overview  Operational Target update  Evaluation Criteria  Discussion  Preliminary Alternative Analysis Goal: elicit feedback in time to solidify operational target and evaluation criteria by 60% draft (due in March)

BUILDING STRONG ® PORTLAND DISTRICT 3 Middle Fork Willamette  3 dams ► Hills Creek ► Lookout Point ► Dexter Big Cliff Detroit

BUILDING STRONG ® PORTLAND DISTRICT 4 Overview  Middle Fork Willamette Downstream Fish Passage and Water Quality / Temperature Control Alternatives Study  Temperature analysis based on water quality model scenarios  Temperature targets I need: ► Operational target (aka model input target) ► Alternative evaluation criteria  Continuation of previous meetings …

BUILDING STRONG ® PORTLAND DISTRICT 5 Update: Operational Target  Used to guide operations (either model or real) on a specific day.  Time variable, instantaneous temperature  Sets a goal, like a rule curve  Determines how much flow should be passed through different outlets

BUILDING STRONG ® PORTLAND DISTRICT 6 Update: Operational Target

BUILDING STRONG ® PORTLAND DISTRICT 7 Alternative Evaluation Criteria  Used to evaluate temperature impacts after the fact.  Should highlight important times and places  Proposing using the percent of days not achieving (daily mean temperature).

BUILDING STRONG ® PORTLAND DISTRICT 9 Upstream Mix (‘no dam’) Calculation  ‘Without Project’ estimate of temperature  Function of: ► upstream temperature measurements ► ratio of flow between tributaries ► 0.11 °C / mile maximum warming ► Assumptions that ungaged tributaries are insignificant or similar to gaged tributaries  Based on Rounds 2010
