Abstract
Cyanobacteria, also known as blue-green algae, are capable of emitting cyanotoxins which are harmful to humans and animals. Harmful Algal Blooms (HABs) occur when cyanobacteria multiply to great densities. Mantua Reservoir in Box Elder County, UT, experiences seasonal HABs, which has resulted in seasonal reservoir closures.
The EnVision team investigated the cause of HABs at Mantua Reservoir by collecting samples from the reservoir’s known point sources and frequently visited recreation areas. The samples were analyzed to determine total phosphorus, nitrate, and cyanotoxin concentrations. The team concluded that excessive phosphorus loading in the reservoir is most culpable for the annual HABs the reservoir experiences. Consequently, the EnVision team recommends a dual faceted approach: implementation of a watershed management plan with the objective of reducing phosphorus loading and a targeted approach to eliminate cyanobacteria that are currently present in the reservoir.
