"Ngoku lixesha lokuqala ukulungiselela iimpembelelo zezikhukula ezinokubakho ecaleni kwechibi nomlambo iMendenhall."
I-Suicide Basin iqalile ukuqukuqela phezu kwedama layo lomkhenkce kwaye abantu abasezantsi kweMendenhall Glacier bafanele ukuba balungiselela iimpembelelo zezikhukula, kodwa akukho nto ibonisa ukuba ukususela kusasa ngoLwesihlanu kukho ukukhululwa kwamanzi kwisikhukula esiqhumayo, ngokutsho kwamagosa eNational Weather Service eJuneau.
Esi sisele, esiye safumana ukukhutshwa kwamanzi minyaka le okwaziwa ngokuba yi-jökulhlaups ukusukela ngo-2011, sigcwele kwaye “ukuhla kwamanzi okufana namanzi agcwala idama lomkhenkce kubonwe kusasa ngoLwesine,” ngokutsho kwengxelo ye-NWS Juneau ekhutshwe ngentsimbi ye-11 kusasa ngoLwesine kwiwebhusayithi yokubeka esweni iSuicide Basin. Le ngxelo ithi kuthathe iintsuku ezintandathu ukususela kwixesha apho isisele sigcwele khona de kube kukhutshwe amanzi kunyaka ophelileyo.
“Kwakuba nje kufunyenwe ubungqina bokutsalwa kwamanzi angaphantsi komkhenkce, kuza kukhutshwa isilumkiso seNkupho,” itshilo ingxelo.
Uhlaziyo olupapashwe ngo-9 kusasa ngoLwesihlanu luthe “imeko ayikatshintshi” ngosuku oludlulileyo.
U-Andrew Park, ingcali yemozulu kwisikhululo esikufutshane nomkhenkce, uthe kudliwanondlebe ngoLwesine ekuseni ukuba ukuchitheka kwamanzi “akuthethi ukuba kukho ukukhutshwa kwamanzi okwangoku.”
“Loo ngumyalezo ophambili — esiwaziyo ukuba ukho kwaye simele silinde ulwazi oluthe kratya,” utshilo.
Nangona kunjalo, kubantu abakuloo ndawo “ngoku lixesha lokuqala ukulungiselela iimpembelelo ezinokubakho zezikhukula,” ingxelo ekhutshwe yi-NWS Juneau iphawula.
Ukusukela ngoLwesine ekuseni, inqanaba lamanzi oMlambo iMendenhall beliziimitha eziyi-6.43, xa kuthelekiswa neenyawo ezimalunga ne-4 ekuqaleni kokukhutshwa kwawo kunyaka ophelileyo. Kodwa uPark uthe into ebalulekileyo kubunzulu besikhukula kulo nyaka kukuba amanzi aphuma ngokukhawuleza kangakanani kwisinki xa idama lomkhenkce liqhekeka.
“Ukuba uvuza kancinci akuyongxaki kangako,” utshilo. “Kodwa khupha onke loo manzi ngaxeshanye unokuba neengxaki ezinkulu.”
I-US Geological Survey ifake izixhobo ezintsha zokubeka esweni kwibhulorho yoMlambo iMendenhall eBack Loop Road ngoLwesine kusasa ukunceda ukukhokela amalungiselelo okukhupha amanzi kwiSuicide Basin. Kunyaka ophelileyo xa kwakhutshwa amanzi nge-5 ka-Agasti, i-USGS yaxhomekeka kuphela kwi-Mendenhall Lake stream gauge yayo.
URandy Host, ingcali yezamanzi kwi-USGS, uthe isantya sokulinganisa amanzi siya kuvumela ukuba kubekho uqwalaselo olongezelelekileyo lwamanzi adlula emlanjeni.
“Iza kwenza iqonga, into esiyibiza ngokuba bubude begage, njengokuba umlambo uphakame kangakanani,” utshilo. “Kwaye emva koko iza kwenza isantya somphezulu. Iza kulinganisa ukuba amanzi akhawuleza kangakanani kumphezulu.”
Uninzi loMlambo iMendenhall ngoku luzaliswe ngamatye okukhusela izakhiwo emva kokuba izikhukula zonyaka ophelileyo zitshabalalise kakhulu unxweme lomlambo. Izikhukula zitshabalalise kancinci okanye ngokupheleleyo izindlu ezintathu kwaye ezinye izindlu ezingaphezu kwamashumi amathathu zineengxaki ezahlukeneyo.
UAmanda Hatch, onendlu ezaliswe ngamanzi angama-intshi asibhozo kwindawo yokukhasa kunyaka ophelileyo, uthe ulungiso olukhulu lokukhusela ngakumbi ikhaya losapho lwakhe lusandula ukugqitywa.
“Asikhathazeki kakhulu kuba siyiphakamisile indlu kangangeenyawo ezine,” utshilo. “Kodwa sinayo imoto yombane, ngoko ke ukuba izele ngamanzi siza kuyithutha imoto siye endlwini yomhlobo. Kodwa sikulungele.”
Indawo yokukhasa yendlu nayo iqinisiwe ukuze ikhuseleke kwizikhukula, utshilo uHatch. Uthe i-inshorensi ayizange ihlawule umonakalo kunyaka ophelileyo, kodwa uncedo lwentlekele kunye nenkxaso-mali efunyenwe yi-federal Small Business Association incede ekwenzeni ukulungiswa nokuphuculwa kube nokwenzeka.
Ngaphaya koko, utshilo uHatch, akukho nto ingako inokwenziwa ngaphandle kokujonga okwenzekayo.
“Akukho nto ichazayo ukuba kuza kuhamba njani, akunjalo?” utshilo. “Kusenokuba phezulu. Kunokuba ngaphantsi. Kunokuba kancinci. Kufuneka silinde ukuze sibone. Ndiyavuya ukuba uluhlu lwethu lugqityiwe ngoko akufuneki sikhathazeke ngayo.”
UMarty McKeown, onendlu eyonakele kakhulu eyashiya umngxuma ovulekileyo ngaphantsi kwegumbi lokuhlala, uthe usalungisa ikhaya kunye nepatio eyakhukuliswa yimvula - kwaye ngaphandle kwemali mboleko ye-SBA akafumananga ncedo awayelulindele kwisixeko okanye kwamanye amaziko karhulumente. Uthe "unenkxalabo enkulu" malunga nemeko yangoku, kodwa akaphazami njengoko ejonga imeko yesitya.
“Siza kujonga umlambo size sithathe amanyathelo ukuba kuyimfuneko,” utshilo. “Andizukuqala ukuphuma endlwini yam. Siza kuba nexesha ukuba kukho into eyenzekayo.”
Irekhodi elitsha lemvula ngoJulayi libekwe eJuneau kwinyanga ephelileyo, kunye nengxelo yokuqala ebonisa ii-intshi ezili-12.21 zemvula kwiSikhululo seenqwelo-moya saMazwe ngaMazwe saseJuneau xa kuthelekiswa nokuphakama kwangaphambili kwee-intshi ezili-10.4 ngo-2015. Bekukho imvula enokulinganiswa kuzo zonke iintsuku ngaphandle kwezimbini zenyanga, kuquka ii-intshi ezili-0.77 ezilinganiswe ngoLwesithathu.
Uqikelelo lwemozulu ekuqaleni kweveki ezayo lufuna ukuba isibhakabhaka sicwebe kwaye kubekho imozulu entle efikelela kwiminyaka yoo-70.
URobert Barr, usekela-mphathi wesixeko kwiSixeko nakwiBorough yaseJuneau, uthe imvula enkulu eJuneau iyaxhalabisa kuba xa umlambo uphezulu, akukho ndawo ingako yokukhupha amanzi ukuzalisa umlambo. Uthe iCBJ ifumana iingxelo zemeko yemihla ngemihla ezivela kwi-NWSJ.
“Basinika uqikelelo lwabo oluchanekileyo malunga nokuba i-jökulhlaup ibiya kubonakala njani kumanqanaba ahlukeneyo okukhululwa ukuba ibingakhutshwa ngexesha lengxelo,” utshilo. “Ngoko ke yonke imva kwemini siyayifumana loo nto. Kwaye oko kusixelela kona kukuba ukuba i-jökulhlaup ikhutshwe ngoku, kwi-20% ukuya kwi-60% yomthamo uwonke we-Suicide Basin, nantsi indlela ebeya kubonakala ngayo i-jökulhlaup. Ukuba ibingakhutshwa kwi-100% yomthamo we-Suicide Basin — eyakhutshwa kunyaka ophelileyo kwi-96% — nantsi indlela ebeya kubonakala ngayo i-jökulhlaup. Kwaye ngoku ukuba ibingakhutshwa kwi-100% ibiya kuba mbi kunonyaka ophelileyo.”
UBarr uthe isitya asidli ngokukhutshelwa nge-100%. Kunyaka ophelileyo yayiyeyona volumu inkulu isitya esasikhutshelwe ngayo ngaxeshanye. Kodwa akukho ndlela yokwazi ukuba amanzi aza kukhutshelwa ngesantya esingakanani.
