Division of Mining, Land and WaterWater Resources Section
Alaska contains more than 40%of the Nation’s surface-water resources.
DNR-Major Water IssuesImpact to aquifers from population growth in Matanuska-Susitna Valley north of Anchorage.Cumulative impacts to Anchorage area streams and aquifers due to increasing use of groundwater for cooling commercial/government buildings.Increased water use for mining projects Growth in water use for oil and gas development.20+ proposed Hydroelectric Projects due to the rising cost of energy.Alternative Power Generation

Alaska’s Geothermal Resources
Mount Spurr – Recent Geothermal Lease Sale
Alaska is located in the Pacific Ring of Fire.
Geothermal Projects Throughout Alaska
Geothermal on the Island of Akutan – Beginning to drill exploration wells summer 2010
Hydrokinetic – River & Ocean Tidal• Hydrokinetic Technology use vertical or horizontal axis
turbines similar to those developed for wind generation• Currently there are 5 FERC applications for Tidal• One River project has been tested in Alaska near Ruby• Studies and permitting occurring for 7 projects
throughout Alaska
Rt: Ruby project Above: Ocean Renewable Power Company’s Design
Question• How would you regulate hydrokinetic?
• In-River under water turbine – water passively turns it
• In-River sitting on the surface turbine - water passively turns wheel
• Tidal – sitting on Ocean floor
