If you’re wondering what aquaponics is, you’re not alone.  Tracing its roots back to the Aztecs and rice cultivation in South China, aquaponics is a combination of aquaculture and hydroponics – growing fish and plants together in a symbiotic system.  Basically, the plants keep the water clean for the fish to grow, and the fish fertilize the plants. Both help the other to survive and thrive.

A wide variety of foods—lettuce, beans, broccoli, cucumbers, peas, herbs, strawberries, melons, and tomatoes, for example—all flourish through aquaponics farming.

You can actually feel the wonder while discovering a new side of the U.S. Forest Service at Shedd Aquarium’s new Great Lakes Exhibit At Home on the Great Lakes.

The Shedd Aquarium, on famous Lake Shore Drive in Chicago, unveiled the exhibit as part of its renovation of the facility’s historic Local Waters Gallery. The exhibit features exciting new interactive components. Visitors experience a connection to the Great Lakes through hands-on learning and up-close encounters with native Great Lakes species.

“There is a strong connection between the health of national forests and the health of the Great Lakes,” said Regional Forester Kathleen Atkinson. “The Forest Service is thrilled to collaborate with the Shedd Aquarium to raise awareness about the interconnectedness of these resources.”

The Chesapeake Bay Watershed, the largest estuary in North America, covers 64,000 square miles and includes more than 150 rivers and streams that drain into the bay. Roughly one quarter of the land in the watershed is used for agricultural production, and agricultural practices can affect the health of those rivers and streams, and ultimately the bay itself.

While the health of the Chesapeake Bay has improved since the 1970s, excess nutrients and sediment continue to adversely affect water quality in local rivers and streams, which contributes to impaired water quality in the bay.

After nearly a century, a five-mile stretch of the Lower Oak Grove Fork of Oregon’s Clackamas River will have native fish swimming year-round in this restored stream once again.

Early in the 20th century, the growing communities around Portland needed hydroelectric power. The Oak Grove Fork dam, located in the foothills of the Cascade Range some 30 miles east of the city, was one of several in the region built to help fill that need.

Unfortunately, by impounding the steam’s water and diverting it for power generation, the river was denied its natural seasonal rise and fall which hindered the movement and spawning of fish.

Lake Tahoe, the country’s highest alpine lake, is no goldfish bowl.

But U.S. Forest Service fish biologists with the Lake Tahoe Basin Management Unit said they’re well-acquainted with the big goldfish – several pounds and up to 4 to 8 inches long – living in the large freshwater lake along the border between California and Nevada.

To date, the Tale of Two Rivers conservation campaign has generated an original microbrew, an annual cycling event, a paint-a-thon and a movie screening.

Now up: a modern quilting bee.
