Brigham City weighs treatment options for Mantua Reservoir toxic algae blooms

Brigham City officials are actively evaluating new treatment strategies to combat toxic algae blooms at the Mantua Reservoir. The urgency for a solution follows the failure of the city's previous management approaches to deliver the lasting results required to keep the water safe for public and animal use.

On July 8, the Bear River Health Department issued an official danger advisory after laboratory testing revealed toxic algal levels exceeding safety thresholds. This advisory has severely limited recreation at the reservoir, causing concern for local residents who rely on the area for summer activities and highlighting the persistent nature of the blooms.

The ongoing issue is a significant concern for the Box Elder community, as the health of the reservoir is tied to both environmental sustainability and the local tourism economy. City officials are under pressure to identify effective, long-term solutions that will allow the reservoir to return to safe, operational status as quickly as possible.
