A sewage spill in Moses Lake’s waters in the Knolls Vista neighborhood reported Wednesday has resulted in a seven-day no contact advisory from the Grant County Health District.

This means the public should not swim, fish, or have any contact with lake water in the impacted area. The public is also advised not to irrigate using lake water.


The sewage spill was initially reported to be spilling into Parker Horn near Downtown ML at around 6 p.m. Wednesday, Aug. 28 by a resident living in the 300 block of West Northshore Drive. The Moses Lake Fire Department, along with the City’s Waste Water Division, responded to the call. Waste water employees worked on the leak and capped the leak around 11:30 p.m. according to the City of Moses Lake. The City stated that employees determined that there was a baseball-sized hole in the side of the pipe which was more than likely a result of an aged un replaced pipe.


Immediately following the spill, the Grant County Health District issued a health advisory with assistance from Grant County Sheriff's Office's Emergency Management. The Health District and Emergency Management contacted more than 70 homeowners along Northshore Drive advising homeowners to discontinue irrigating from the lake until further notice. The Health District is also installing public health advisory warnings in the affected areas. This release does not affect drinking water and no sewer services were affected.


In a statement earlier this afternoon the City of Moses Lake stated,

"City staff is working on options to discontinue the use of the aged pipe with the goal of keeping this issue from happening in the future."
