How Ice Jams Form (Source: NWS, USA Today)
Most Likely Locations for Ice Jams is Where the River’s Transport Capacity is Exceeded • Obstructions in the Channel – Islands, Locks, Bridge Piers, Docks • Changes in the Channel – Narrowing of the Channel, Bends, Gorges, Intact Ice Cover • Change in the Channel Depth – Deep water to Shallow water • Merger of River Channels
Economic Impacts - Ice Jams • Damage Totals Approximately $125 Million Annually • Interference with Navigation • Reduced Hydropower Production • Channel Erosion and Damage to Channel Training Structures • Other Costs - Fish, Wildlife and Their Habitat (Source: CRREL)

Ice Jam Training and Mitigation Workshops 2009 • 2/9/2009 Washington Volunteer Fire Department Washington, CT Attendance: 19 • 2/25/2009 Montgomery County EMO Fonda, NY Attendance: 35 • 3/3/2009 Warren County Sheriffs Office Lake George, NY Attendance: 17
Thermal Breakup vs. Mechanical Breakup • Ice Cover Melts in Place • Direct Sunlight Plays a Large Role • Surface Color Influences Sunlight Absorption, Dusting • Water on Ice Decreases Reflection, May Promote Melting • Open Water Areas Absorb Sunlight • Hydrodynamic Forces Acting on Ice Cover Exceed Cover Strength • Results from an Increase in Flow • Precipitation Event • Snowmelt Event • Dam Operation (Source: CRREL)
Attempts To Control The Ice Regime To Lessen The Impacts Of Ice Related Problems Include: • Fixed Structures – Tension Weir, Sloped Block Ice Control • Ice Booms • Channel Modification • Dusting, Hole Drilling • Mechanical Weakening (Source: CRREL)
Mechanical Weakening • Immediate Strength Reduction. • Four Most Common Methods: Excavation - Bulldozer, Clam Shell Blasting Dynamite, Aerial Ice Cutting - Trencher, Ice Saw Ice Breaking - Amphibious Excavator, Vessels, Wrecking Ball (Source: CRREL)

Ice Breaking Ice covers can be broken prior to natural breakup using ice breaking vessels or construction equipment. Downstream movement of the broken ice should be enhanced to prevent localized breakup ice jams. Ice breaking is particularly useful to ease navigation in larger rivers and lakes. (Source: CRREL)
Video of Amphibex on Nechako River in British Columbia (Source: Prince George Citizen)
The Amphibex story, in my mind, is all about modern-day technology working with Mother Nature to create what is now a long, open channel that gives the water some place to go, and the water level has dropped substantially, " he said. "So the little green grass hopper was able to work only nine days, but you know what, it did a great job. " Quote from Prince George Citizen 1/29/08
A Dangerous Ice Jam Mitigation Activity! (Source: CRREL and NBC 2 News)
Conclusions • Ice Jam Training and Mitigation Workshops have had Some Success Mainly with Excavation Methods (Bulldozer, Clam Shell) • Other Methods Need to be Utilized Including Sloped Block Ice Control Structures in Non-Navigable Bodies of Water as well as Hydroseeding and Ice Breaking on Larger Bodies of Water
