The Swan-Canning River is the estuary adjacent to Perth, the capital of Western Australia, and its seaport, Fremantle at the mouth.

The use of red, yellow and green for denoting different levels of concern in environmental report cards has its origin in human perceptions of color.

The Maryland Coastal Bays Program report card was released at an interesting venue in Ocean City in late afternoon, June 30.

The 2009 Chesapeake Bay report card release was held at Gunpowder Falls State Park in Baltimore City on May 18.
