DESERT SPRINGS, Utah (AP) -- Crews recently completed work on a barrier in the Virgin River Gorge aimed at blocking invasive species to help save endangered fish.
Work is done on a $300,000, 6-foot-high concrete barrier that will block invasive species from Lake Mead and its tributaries from getting into the southern Utah section of the river.
That section is the only place where the Virgin River Chub and Woundfin thrive.
The two species were almost wiped out as of about five years ago. Invasive species like the Red Shiner swam upstream from the lake and started to displace the native species.
Last week wildlife officials reintroduced 3,400 chub into the river. The new barrier is the last of that type of structure planned.
