Owings Mills, MD-Join Maryland Public Television (MPT) for a week's worth of all things Chesapeake Bay-from food and art to wildlife and pressing environmental issues-with MPT's third annual Chesapeake Bay Week, April 21-29.

Both children and adults will delight in over 20 hours of captivating and original programming that celebrates our national treasure-and even gives viewers a chance to donate volunteer hours to clean it up during MPT's first annual Chesapeake Bay Week Volunteer-a-thon, airing live Sunday, April 29 at 7 p.m.

Highlights of this year's Chesapeake Bay Week include:

• A special edition of MPT's award-winning Outdoors Maryland, Hidden Rivers, airing Tuesday April 24 at 7:30 p.m., will explore the little-known impact of Maryland's storm water runoff-chemicals, petroleum products and other pollutants from paved surfaces-that eventually make their way into the bay.
• A closer look at the first permanent British colony in the New World in Jamestown: The Buried Truth, airing April 25 at 8:30 p.m., as archeologists recount major discoveries that provide a more complete story of what really happened at Jamestown.
