Flowage pic

This is a man-made flowage created when a local creek was dammed some years ago and features some of the finest scenery in the region year around.  The flowage contains many fish species, but does not give them up easily. There is also abundant wildlife – birds, ducks, geese, deer, a wolf pack or two.

This is one of those remote areas where a vehicle can be faintly heard for several miles and it will seem to take forever to go by not getting much louder as it does. This shot was taken last August at dawn.The photographer is camped nearby.

Lampreys offer lessons in federal Asian carp response

Federal officials trying to prevent invasive Asian carp from infiltrating the Great Lakes are using many of the same techniques used to fight the sea lamprey, a parasite that was once as feared as Asian carp but has been largely brought under control.

Though the work has been long and costly, lamprey populations have been cut by about 90 percent in the Great Lakes, suggesting that an Asian carp invasion — should it occur — would not necessarily cripple fishing and recreation industries as feared.
“When a lot of people say, ‘The game is over’ when it comes to Asian carp getting into the Great Lakes, I don’t think so,” said Michael Hoff, invasive species coordinator at the U.S. Fish and Wildlife Service. “It’s a different game we play. But it’s not over.”
Federal agencies have used toxic chemicals and barriers to keep lampreys at bay, as they are now doing with Asian carp. Researchers also use pheromones to attract or repel the lampreys, interfering with their spawning patterns.
The U.S. Geological Survey is developing the same technology to fight Asian carp, said Leon Carl, the agency’s Midwest regional executive. Though the project was discontinued due to lack of funding, recent federal research funding through the Great Lakes Restoration Initiative will allow it to move forward, he said.
If the lampreys provide precedent, though, the Asian carp response will remain expensive for decades. More than 60 years after lampreys first invaded the Great Lakes, the federal government continues to spend $20 million to $30 million per year fighting them, Carl said
