Suicide Basin is currently releasing water into Mendenhall Lake and Mendenhall River. At this time, it is too early to know the scale of the outburst. Please avoid the Mendenhall River for the safety of yourself and others until further notice.
Residents in the vicinity of the river, especially those to the west of Riverside Drive, are strongly encouraged to make an evacuation plan and prepare a go-bag in case of emergency.
CBJ and local weather agencies will monitor river conditions closely over the coming hours. If the river appears to be approaching flood levels, CBJ will work with CCFR and JPD to alert residents in the area and issue evacuation warnings if necessary. CBJ is prepared to open sheltering services in the event of a major flood.
Additional updates will be provided when more information is available.
