A sign warns about the electronic fish barrier at the outlet of Lower Gar Lake near Milford, Iowa, on July 30. The device has successfully stemmed the invasion of Asian carp, officials say.

MILFORD, Iowa | Three years after two Asian carp were netted in East Lake Okoboji, officials believe they stopped the voracious aquatic invaders.

The invasive species swam into the lakes during flooding in 2011. One species, silver carp, poses a safety hazard due to its propensity for leaping from the water when startled.

Officials believe a $1 million electronic fish barrier should be enough to keep more Asian carp from entering the lake system and threatening the $300 million tourism industry. Officials believe the fish can't reproduce in still lake waters, so keeping more carp from swimming in will protect the lakes from being overrun.

It can happen. A South Dakota lake was so overrun by Asian carp and other undesirable fish that officials will kill off all of the fish and restock. Such drastic action shouldn't be necessary in the Iowa Great Lakes, officials say.

1. Are there no gar in gar lake?

Seems like a gar would be able to dispatch an asian carp or two.
