Study: Urban Development Degrades Streams

Nov 21, 2012

Scientists recently looked at what urban development is doing to streams in Portland and eight other U.S. cities. They found that urban development can mean trouble for invertebrate species.

That’s especially true in pristine waters running through forests.  Development from expanding cities can make streams flow faster.  It also changes habitat and increases pollution.

A study by the U.S. Geological Survey found that all that can kill insects like mayflies, stoneflies and caddisflies.

Hydrologists from the Natural Resources Conservation Service call the latest snow survey results "March Madness in Idaho."  Storm after storm hit the state in March, marking one of the greatest one-month changes in snowpack on record.
