TWIN FALLS, Idaho — Officials are closing Shoshone Falls Park to all visitors beginning Friday, September 29, in an effort to contain and treat the infestation of quagga mussel larvae found in the Snake River.

Centennial Park has also been included in the closure.

Earlier this month, portions of the Snake River in Twin Falls were shut down from public access for water access and sporting after the invasive species larvae was detected.

During the closure, Shoshone Falls Grade at the intersection to Dierkes Lake Park will be closed to all vehicles, cycling, and pedestrian traffic. Trails in Shoshone Falls Park will also be closed. Dierkes Lake Park and its trails will remain open to the public, but water access is prohibited in the lake.

The length of the closure is unknown at this time, as ISDA treats the area spanning between Twin Falls and Niagara Springs.

A town hall on the issue will be held 5pm on Sunday, Oct. 1 at Twin Falls City Hall and it will be live-streamed to City of Twin Falls website.

Quagga mussels are one of the most aggressive species in US waters, and larvae can be easily spread by watercraft and gear used in the water, i.e. waders, fishing lures, paddleboards, oars, etc.
