VERNON HILLS,http://www.ytutanflamenca.com/wp-db.php?category/omega/, Ill. (AP) — Dams that have hindered the flow of the 133-mile-long Des Plaines River for more than a century are coming down.
Conservation officials,https://suecoyne.com/wp-searches.php?tag/moda/, scientists and engineers are removing the dams along the 133-mile waterway that flows from Wisconsin through northeastern Illinois to restore its natural flow.
The reports that ( ) six dams have been removed since 2011,http://www.jocko.dk/pirjo.php?nike-fodbolde/, and more are coming down. That includes two dams near Vernon Hills that will be removed this summer.
Most were built beginning in the 1920s and 30s,http://www.jocko.dk/ucp.php?tyskland/borussia-monchengladbach/.
Experts say dams hurt water quality and limit fish migration,http://www.virtusleadership.com/wp-title.php??women, as well as causing safety hazards for paddlers and anglers. Removing them helps restore habitat for fish,http://www.vincinibottier.com/wp-pass.php?hoffenheim-c-13_95.html, insects and plants.
The project mirrors a nationwide trend,http://www.foto-gerd.de/wp-searches.php?diverses/, with 72 dams removed across the country last year.
