1 Management Perspectives: Kate Day and Caty Clifton Blue Mountains Adaptation Workshop, April 23, 2014 La Grande, OR

2 Top Down Flow sensitivity VIC peak and low flow model projections (Wenger et al) Bottom Up Regional Snowpack Vulnerability Mapping in the Blue Mountains (Kramer and Snook, and Luce), OSU geohydrologic model outputs (Safeeq et al)

3 Management Issue: Infrastructure - Roads Management Issue: Water Uses (Consumptive) Moving towards adaptation Watershed conditions influenced by climate and hydrologic changes, and non climate stressors Current and future conservation and restoration strategies and priorities (Management Actions)

4 From: Water, Climate Change, and Forests, Furniss et al, 2010)

6 Subwatersheds with >5% FS ownership 498 Total

7 Kramer and Snook, 2014, Luce et al, 2014

8 Flow Data. Western US Stream Flow Metric Data Sets Used in Analysis Interior Columbia and Pacific Northwest Wenger et al, 2010

9 Roads Vulnerable to increases in flow magnitude Also vulnerable to timing of flow and precipitation more resource impacts if high flows come during times of high use

10 Umatilla River, January 1965, Upper Left Desolation FR 1000, May 2011, Middle Left NFJD FR 5200, May 2011 Lower Left Pine Creek June 2010, Upper and Middle Right FR 39 Lake Creek CG access road Lower Right June 2010

13 2080 Bankfull Flow Change Predictions on Streams within 300ft of Roads

15 Miles of road in each category No Data <1 1-10% % % >30% Total % of total road miles

17 Maps show areas of greatest vulnerability and are a first step to assessing vulnerability Tie in with local forest and district-level knowledge Crosswalk with bottom-up analysis products (Safeeq et al) Further refine priorities with GRAIP and/of GRAIP Lite NetMap Data generated can inform TAP, Legacy Roads program, WCF, and Key and Priority watersheds. Working on analysis using W95 VIC parameter to look at change in timing (and potentially magnitude) of higher flows.

27 Implement water conservation practices Anticipate requests for storage and flow augmentation Resource inventory - Getting our data house in order BMPs An ounce of prevention Active Restoration Priority Watersheds and Activities Legacy Roads Program and Subpart A (Transportation Analysis) Environmental Education and Community engagement on water conservation and restoration

28 Priorities for active restoration, based on R6- Aquatic Restoration Strategy and National Watershed Condition Framework.

29 In 2011, the National Forests classified Watershed Condition, prioritized based on current management strategies, and selected 17 priority subwatersheds for active restoration investment
