Climate & Future Water Management
How is climate predicted to change in Hood River
County? (Modeling for 2030 – 2060)
How will water availability for irrigation be
affected?
What are the alternatives?
What will fish habitat availability look like under
these alternatives?

Options to Increase Water Availability
Using more Groundwater (currently evaluating potential impact & recharge possibilities)
Increasing Reservoir Storage
Potable Water Conservation (comparatively low impact)
Irrigation Water Conservation – conveyance, on-farm, fallowing of annual crops
Hydropower- reduce summer diversions, off-set with winter diversions

Effects of Sub-optimal Irrigation Practices
Poor crop performance due to insufficient or uneven application of water (Ex. application rate exceeds absorption rate of
soil, some trees get too much, some not enough)
Leaching fertilizer out of root zone; washes into ground water or surface water- waste of money
Surface runoff leads to soil erosion on slopes
Higher labor cost
![Page 19: Hood River Water Conservation Strategy - ODFW Home … · Hood River Water Conservation Strategy: ... Surface runoff leads to soil erosion on slopes ... demand + increased conservation](https://reader033.vdocument.in/reader033/viewer/2022051601/5ad9a44f7f8b9ae1768c1de4/html5/thumbnails/19.jpg)
Benefits of Improved Irrigation Practices
Optimize fruit yield and quality (reduce incidence of cork
spot & alfalfa greening in pears)
Optimize canopy development and efficiency: avoid excessive
shade, promote return bloom & fruit set
Optimize inputs & minimize costs (nitrogen, water, pruning)
Ability to adequately water in a low-water year- maintain fruit
size and profit margin
![Page 20: Hood River Water Conservation Strategy - ODFW Home … · Hood River Water Conservation Strategy: ... Surface runoff leads to soil erosion on slopes ... demand + increased conservation](https://reader033.vdocument.in/reader033/viewer/2022051601/5ad9a44f7f8b9ae1768c1de4/html5/thumbnails/20.jpg)
Improving Irrigation Management
Design and maintain
irrigation systems for uniform
and efficient watering
Use soil moisture monitoring
and evapotranspiration
estimates to optimize water
availability to crops (Match
irrigation application to crop
demand)

Future Management Scenarios under
Median Climate Change
“Historic”: Reflects current management practices, infrastructure, and average stream flows (1980- 2010)
“Future”: Climate change but no management, infrastructural, or demand changes
“Increased Demand”: Climate change + increased demand
“Increased Conservation”: Climate change + increased demand + increased conservation
“Increase Storage”: Climate change + increased demand + increased conservation + increased storage

Next Steps
Continue to Explore Innovative Ways to Increase Water Availability
Water Bank- mechanism for temporary leasing of water rights
Shallow Ground Water Recharge-need to conduct feasibility study
Fund Raising
State & Regional funding sources: 4 local irrigation districts recently applied for approximately $7 million from OWRD for distribution piping & reservoir expansion
Environmental Quality Incentives Program (NRCS): federal $ can cover 50% of on-farm irrigation upgrades; OWEB small grants
Local sources? (Example- MFID has a cost-share program)
