Study links Treasure Valley to Snake River Algae
Researchers from the US Geological Survey say farms and sewer systems in the Treasure Valley region are dumping enough phosphorus into the Boise River to contribute to algae blooms and fish kills in the lower Snake River.

Phosphorus causes algae to grow rapidly, making water murky and depriving fish of oxygen. The data collected during the two-year study has found that Boise River contributes about 30 percent of the phosphorus to that particular stretch of the Snake River, including 72 percent of the form of phosphorus that is linked to algae growth.

The largest sources of phosphorus in the region are wastewater treatment plants, agricultural runoff, and storm water drainage. Installing sediment ponds on local farms may be necessary to remove the phosphorus from the water that runs off of fertilized fields.

Asian Carp Creeping Toward Lake Michigan - A bill currently before Congress could lead to the installation of seismic water guns below the lock to make it harder for the carp and other species to swim upstream.
