Eugene -Springfield Area Natural Hazards Mitigation Plan <br />6. Appendices <br />released would breach Lookout Point and Dexter dams, increasing the potential impact <br />to the Eugene -Springfield area. <br />In 2010 and 2011, the Portland District of the U.S. Army Corps of Engineers updated <br />the Dam Failure Inundation Maps and the Emergency Action Plans for their projects in <br />Lane County. Copies of these maps have been provided to Lane County and the cities <br />of Eugene and Springfield for emergency planning purposes, however distribution of <br />the maps is restricted because they contain sensitive information. Persons wishing to <br />obtain copies of the maps should contact the Portland District of the U.S. Army Corps <br />of Engineers. <br />H.4.2 Probability of Future Occurrence <br />To evaluate the probability of a collapse, the dam type for each high hazard potential <br />dam in Lane County should be considered. Table H-2 provides additional information <br />for each dam including type, year built, owner and Emergency Action Plan status. <br />Table H-2 Additional Data on NID High Hazard Potential Dams <br />County <br />Dam <br />River <br />Storage <br />Year <br />Da <br />P <br />Owner <br />Name <br />acre feet <br />Built <br />Type <br />im <br />Lane <br />Cottage <br />Coast Fork <br />50,000 <br />1942 <br />RE <br />Y <br />Corps <br />Grove <br />Willamette <br />River <br />Lane <br />Dexter <br />Middle Fork <br />29,900 <br />1955 <br />RE <br />Y <br />Corps <br />Willamette <br />River <br />Lane <br />Fall Creek <br />Fall Creek <br />125,000 <br />1965 <br />ER <br />Y <br />Corps <br />Lane <br />Dorena <br />Row River <br />131,00 <br />1949 <br />RE <br />Y <br />Corps <br />Lane <br />Lookout <br />Middle Fork <br />477,700 <br />1953 <br />RE <br />Y <br />Corps <br />Point <br />Willamette <br />River <br />Lane <br />Blue River <br />Blue River <br />89,000 <br />1968 <br />RE <br />Y <br />Corps <br />Lane <br />Hills <br />Middle Fork <br />356,000 <br />1962 <br />RE <br />Y <br />Corps <br />Creek <br />Willamette <br />River <br />Lane <br />Cougar <br />South Fork <br />219,000 <br />1964 <br />ER <br />Y <br />Corps <br />McKenzie <br />River <br />Lane <br />Fern <br />Long Tom <br />121,000 <br />1941 <br />RE <br />Y <br />Corps <br />Ridge <br />River <br />Lane <br />Walterville <br />McKenzie <br />345 <br />1951 <br />PGRE <br />Y <br />EWEB <br />Storage <br />River <br />Pond <br />6-133 January 2020 <br />
