Lamprey at Three-MileContinued from Page 31reaches <strong>the</strong> <strong>Umatilla</strong> River as <strong>the</strong> lampreynavigate The Dalles and John Day dams,and enter o<strong>the</strong>r tributaries (John Day,Hood, Deschutes, Klickitat, Wind Riverrivers, and Herman Creek).“We’re losing 50 percent at everydam,” Jackson said.However, without proper monitoring,it’s hard to say exactly how many arereaching <strong>the</strong> <strong>Umatilla</strong>.“I’d like to say <strong>the</strong> adult returns arefrom our translocation program, but it’sdifficult to say without seeing an adultthat was tagged in <strong>the</strong> <strong>Umatilla</strong> River asa juvenile ,” Jackson said. “We’re talkingabout PIT (Passive Intergrated Transponder)tagging juveniles in <strong>the</strong> <strong>Umatilla</strong> andif we get <strong>the</strong>m back as adults <strong>the</strong>n we cansay <strong>the</strong>y were reared in <strong>the</strong> <strong>Umatilla</strong>.”Current knowledge lends to <strong>the</strong> ideathat lamprey are panmiptic in nature,and may not return to <strong>the</strong>ir natal streamlike salmon.Although <strong>the</strong>y can’t say whe<strong>the</strong>r or not<strong>the</strong> returning adults were progeny <strong>of</strong> <strong>the</strong><strong>Umatilla</strong> from released adults (annuallyas many as 600 to as few as 68, dependingon <strong>the</strong> number ga<strong>the</strong>red from lowermainstem dams) in <strong>the</strong> headwaters over<strong>the</strong> last 11 years, <strong>the</strong> <strong>Confederated</strong> <strong>Tribes</strong>can point with “excitement” to this year’sreturn, which is eight times higher thanlast year’s count <strong>of</strong> 17 adults.A number <strong>of</strong> positive factors can beconsidered, Jackson said, not <strong>the</strong> least <strong>of</strong>which is higher flows in <strong>the</strong> lower threemiles <strong>of</strong> <strong>the</strong> <strong>Umatilla</strong> River. That section<strong>of</strong> <strong>the</strong> river <strong>of</strong>ten dries up between lateJune and October, just before and justafter <strong>the</strong> peak migration <strong>of</strong> lamprey,which cross over <strong>the</strong> John Day Dam in aJuly-to-August window.To remedy that low-water problem,BPA has funded baseline flows <strong>of</strong> about75 cfs through <strong>the</strong> federal <strong>Umatilla</strong> BasinProject, which exchanges water from <strong>the</strong>Columbia River for farmers who leave<strong>the</strong> same amount in <strong>the</strong> <strong>Umatilla</strong> for fishduring <strong>the</strong> spring growing season.Jackson believes that extra water haspushed out into <strong>the</strong> Columbia juvenilelamprey pheromones (a chemicalsubstance that triggers migration andreproduction) that attract adult lampreymoving up <strong>the</strong> Columbia.Prior to 2006, those pheromoneswere stopped at Three Mile before <strong>the</strong>additional BPA-funded flows duringthat peak adult migration period. Once<strong>the</strong> adults entered <strong>the</strong> <strong>Umatilla</strong> River<strong>the</strong>y also were stopped at Three Mile, aconcrete diversion built by <strong>the</strong> federalgovernment to irrigate lands in <strong>the</strong> early1900s, which incidentally caused expiration<strong>of</strong> salmon.But now <strong>the</strong> new lamprey ladder on<strong>the</strong> east side <strong>of</strong> <strong>the</strong> river is giving <strong>Tribes</strong>hope that lamprey can make a comeback.Built with funding from BPA’s 10-yearAccords Project Funding and a U.S. Fishand Wildlife Service wildlife grant, <strong>the</strong>pilot lamprey ladder project is designedto see if lamprey can better reach watersabove diversion dams, in this case ThreeMile Falls Dam. Prior to <strong>the</strong> lamprey ladder,<strong>the</strong> fish – sometimes called eels – hadto use outdated salmon bypass ladders orThis year, for an unknown reason, <strong>the</strong> number<strong>of</strong> adult lamprey returning to <strong>the</strong> Columbia Riveris higher than in recent years.suck <strong>the</strong>ir way up and over about 20 feet<strong>of</strong> concrete to <strong>the</strong> o<strong>the</strong>r side.“Of <strong>the</strong> 138 we counted, 115 used <strong>the</strong>new ladder and 23 used <strong>the</strong> existingsalmon fish way or climbed <strong>the</strong> dam,”Jackson said.The fish ladder, with sharp 90 degreecorners, was not suited to lamprey, whichrely on <strong>the</strong> suction <strong>of</strong> <strong>the</strong>ir mouths toreach <strong>the</strong> waters above Three Mile FallsDam. The new ladder has rounded edgeswith a 45 degree climb so lamprey cankeep <strong>the</strong>ir attachment up and over <strong>the</strong>structure. Fur<strong>the</strong>rmore, <strong>the</strong> ladder isequipped with devices to monitor lampreypassage.Although <strong>the</strong> value <strong>of</strong> <strong>the</strong> fish hasbeen generally dismissed, <strong>the</strong> adaptablelamprey is a traditional and ceremonialfood for <strong>Tribes</strong> throughout <strong>the</strong> region.“The <strong>Tribes</strong> have a vested interestbecause lampreys are culturally significant,”Jackson said. “They are a prizedfish to us.”For years, Jackson said, state and federalagencies have given short shrift tolamprey in favor <strong>of</strong> efforts to protect andrestore salmon and steelhead listed on <strong>the</strong>Endangered Species List. Historically, <strong>the</strong>only use for lamprey has been as bait forsturgeon or as fish meal to feed youngfry in fish farms. In <strong>the</strong> 1930s metrictons were collected on barges from <strong>the</strong>Willamette, <strong>the</strong>n ground into fish meal.Jackson is hopeful that anecdotalresults from places like Three Mile andsubsequent research and monitoringwill give lamprey a chance to continue ahistoric lifecycle that as adapted through<strong>the</strong> ice age, eons <strong>of</strong> volcanic disruption,even <strong>the</strong> Missouri Floods that created <strong>the</strong>Columbia River system.“Salmon have been around for 10 to13 million years. Fossil records showthat lamprey have been on earth for 530million years, since before <strong>the</strong> Jurassic Period,”Jackson said, noting that a CBFWA“white paper” is to be published soonthat will provide <strong>the</strong> research behind <strong>the</strong>historic claim.“Lamprey predate dinosaurs,” Jacksonsaid. “These critters are really old and itbo<strong>the</strong>rs me to think that in my lifetime<strong>the</strong>y could potentially go extinct. It’s notacceptable; it’s unfathomable to think<strong>the</strong>y’ve been around that long and couldbe gone within my lifetime.”Q vote Qnov. 15Q vote QJohn Barkley - BOT Treasurer• Experienced• Qualified• Integrity• Dedicated• Protect, Exercise1855 Treaty Rights• Former General Council Chairman• Tribal Water Commission - 12 yearsas Vice-ChairmanServed on:• TERO Commission• Land Acquisition Committee• Economic & Community DevelopmentComittee• Constitution Review CommitteeAs former Tribal Gaming Manager, Gaming Consultant, 12 years <strong>of</strong> experience with TERO, a parent <strong>of</strong> an NCS student, andexperience in Tribal politics, I intend to build on that experience to realize a long forthcomingTribal water rights settlement, a new school, clinic, new housing and community development projects that serve CTUIRmembers and reservation residents.
