Federal authorities are reporting a toxic algae blooms in Lake Powell, the nation’s second-largest reservoir.
The algae isn’t likely to harm downstream users that depend on Lake Powell’s water supply. But retired federal water scientist David Wegner says we need to keep a close eye on smaller reservoirs that feed directly into the drinking supply.
"Many of our water treatment plants that take water directly from a surface water source like a reservoir or lake, perhaps they don’t have the facilities to actually clean and ensure that that water supply is adequate for the public," Wegner said.
Wegner says major water agencies in Phoenix, Denver and Los Angeles are stepping up monitoring efforts.
