  1. Seeking Water Security: Harvesting Glacial Meltwaterand Early Snowmelt with Managed Aquifer Recharge AWRA–CAS Water Security Conference 16-18 September 2019 Beijing Michael E. Campanawaterwired.org @WaterWiredMaria T. Gibson@groundwatergeekgroundwatergeek.comOregon State UniversityCorvallis, OR

  2. Talk Organization Glacial Meltwater & MAR How Did We Think of This? Where Can This Be Done? Early Snowmelt and Floods Issues Things to Accomplish Yakima River Basin Project

  3. What is MAR? Managed Aquifer Recharge is the intentional recharge of water to suitable aquifers for subsequent recovery or to achieve environmental benefits. The managed process assures adequate protection of human health and the environment.Western Australia Government: http://bit.ly/2eLyLoFFor terminology see: https://bit.ly/2OyXxeU

  5. What Can MAR Do?It can reducevulnerability to climate change and hydrological variability. It can help control overpumpingand restore groundwater balance. It can recharge aquifers, control saltwater intrusion or prevent land subsidence. It can also sustainor improve the functioning of ecosystems and groundwaterquality; mitigate floods.

  7. How Did We Think of This?MEC visited Copiapó, Chile, in the Atacama Desert, in 2008

  8. Copiapó ( c. 160,000) is on the banks of the Copiapó River - which flows!Averages about 19 mm (0.75 inches) of rain per yearMining is a big industry, along with agriculture (table grapes, olives, tomatoes, some citrus)

  9. Concern for Water Supply Agriculture and mining use large amounts of water Conflict over water resources Accelerated glacial melting Subsurface storage of meltwater?

  10. Where Can MAR Be Done? Some Places Where MAR of Glacial MeltwaterMight Work (Sufficient Water Available) Andes; Karakoram, Pamir, Himalaya, and related mountain ranges and Tibetan Plateau; Rocky Mountains; Alps; Zagros and Caucasus Mountains; Pyrenees; Cascade RangeNote: Annual glacial runoff just to the Gulf of Alaskais 57 cubic km (> 46 MAF ~ 2 full Lake Meads!)See: https://bit.ly/2UmfIK4Annual loss of snow & ice: 369B tonnes, > 50% fromNorth America.

  11. White River Glacier, Mt. Hood, Cascade Range, Oregon(thanks to Anne Nolin)

  12. Early Snowmelt We are seeing early snowmelt in the Cascade Range of the Pacific Northwest Streamflow is peaking earlier, causing potential issues with flooding, landslides, water storage, environmental needs, etc. These issues will be exacerbated as the temperature warms The McKenzie River hydrograph following the Oregon precipitation map illustrates this This early snowmelt is also occurring in the Yakima River in Washington State and elsewhere

  13. Mean Annual Precipitation in Oregon The State of Water Resources in Oregon: Location

  14. Streamflow – McKenzie River Basin 1948-52, 2001-05, Future(Jefferson et al., 2008: http://bit.ly/2eAXtcb) Peak flow has shifted from spring into winter – possible flood hazard and storage issues Decline begins earlier and summer flows are lower

  15. Flood FlowsAside from harvesting early snowmelt, MAR could be useful in mitigating flood hazards and recharging aquifers by storing flood waters. Seerecent case study in Texas(which gets littlesnow!):http://bit.ly/2ZR2UyT

  16. IssuesNot SustainableLegal and Institutional Subsurface Availability & SuitabilityDownstream/Ecosystem IssuesConflictAssorted Technical IssuesEconomicsNeed

  17. Things to Accomplish1) Identify Suitable Areas2) Identify Legal, Institutional & Other Issues3) Cost, Need, Local Enthusiasm

  18. Yakima Basin1) 15,700 square km; rises in Cascade Range, flows SE to Columbia River 2) c.360,000 people; productive agriculture - $4B annually; IWRMplan adopted(see https://bit.ly/2usfiTS)3) Tribal interests - Yakama Nation 4) Important salmon habitat (ESA)

  19. Yakima River Basin (YRB) Project1) Identify suitable MAR horizons in Columbia River Basalt aquifers (highly compartmentalized)2) Store ‘excess’ surface water via wells in CRBs or infiltration3) Withdraw water as needed to supplement irrigation and ecosystem needs4) Funded by Washington Dept. of Ecology

  21. The Water King’s Three Commandments! • “A fool and water will go • go the way they are diverted.” • – African proverb • 2) “There are lies, there are damn lies, and there are hydrologists’ reports.” – Texas legislative hearing, 2 February 2016 • 3) Bottled water = $3.2M/acre-foot • (see #1)
