South Fork State Recreation Area, which is seven miles south of Elko, has tested positive for quagga mussel DNA.

No adult quagga mussels or veligers (larval stage quagga) were found in that waterway, according to the Nevada Department of Wildlife. The reservoir is not considered infested at this time. Infestation is declared when adult quagga mussels are found in a body of water.

All boats entering or exiting the South Fork State Recreation Area will be subject to a mandatory inspection. NDOW is telling all boaters leaving South Fork to remove their plug, drain all water and dry their boat for at least five days before using that boat on another waterway. Alternatively, these boats can undergo commercial decontamination.

Mandatory inspection will continue until the end of October.

Quagga mussels can cause irreparable damage to a waterway.
