May 12, 2000 - First there was the fish-cam, then the bear-cam…now visitors to the World Wide Web can see "Lake Superior Cam."

May 24, 2000 - Mainstreet Radio's Leif Enger reports that on the Rainy River, the border between Minnesota and Canada, lake sturgeon is rising. Surviving near obliteration by commercial fishing and polluting paper mills, the sturgeon has resurfaced as a gamefish of almost mythical power. With the coming of summer, anglers by the hundreds of thousands are stalking Minnesota's lakes and rivers. Their objective, almost always, are walleye, northern pike, panfish and trout. Yet for a few anglers, a walleye holds no attraction; a twenty-pound northern, no allure; a rainbow trout, no romance…but lake sturgeon is a different matter.

As Daniel Zwerdling reports for NPR News and ARW, there's a moral to this story: when humans try to outwit nature, it can strike back with a vengeance.
