Eurasian Watermilfoil is a submerged aquatic plant that grows in still or slow-moving water. It probably arrived in North America in the 1940s. It quickly spreads by growing off of broken stems, crowds out native plants and forms dense mats that interfere with recreational activity.

Parker Dam Road: The “Thread of Life” Back Country Byway: 11 miles below the dam with interpretive pullouts re history and nature along the Colorado River
“It can likely be safely assumed that this area will never be returned to a natural state even if there were no man-made structures, as long as the dam is intact. That is the trade-off for the human presence here, and why the re-vegetation effort of various groups is so important.” — On the Road – Needles to Blythe
