Shirkadda JF Brennan, Inc. ee La Crosse, Wis., ayaa horumar weyn ka samaynaysa mashruuca qodista harada Redwood ee Minnesota.
Marka loo eego Aagga Xakamaynta Wabiyada ee Redwood-Cottonwood (RCRCA), saddex toddobaad markii uu mashruuca socday, JF Brennan waxa uu ka daadiyay in ka badan 76,000 cubic yards oo harada Redwood ah, isaga oo si tartiib ah ugu sii socda yoolka 650,000 oo yaardi kuyuub ah.
"Laga bilaabo usbuuca May 16, Micheal B. dredge wuxuu u dhaqaaqi doonaa meel u dhow biyo-xireenka wuxuuna bilaabi doonaa inuu ka shaqeeyo jihada koonfureed ee goynta ugu qoto dheer si loo soo celiyo harada iyo kanaalka Redwood qotoma qoto dheer," ayuu yiri RCRCA ."Ugu yaraan 100 cagood u jirta biyo-xireenka, iyo sidoo kale 25 cagood oo xeebaha ah, ayaa looga baahan yahay hawlgallada qodista iyo shuruudaha oggolaanshaha."
RCRCA ayaa sidoo kale ku dartay in dheecaanka wasakhda ah ee ka soo baxaya Xarunta Dewatering Confined Dewatering (CDF), oo si kale loo yaqaan balliga dewatering, la sii daayay markii ugu horeysay May 12. Tayada daadinta biyaha waa la kormeeraa si loo hubiyo inay buuxiso heerarka la oggol yahay ee turbidity, fosfooraska iyo Baahida noolaha ee carbonaceous (CBOD).
