CommentsEurasian watermilfoil has been found here previously. Some samples were given to the herbarium at Utah State Univ. The shorter fronds have closer spacing between nodes, but the longer ones have greater internode spacing that is supposed to be diagnostic for this species. Abundant at shallower depths. A beetle has been introduced by the Utah Div. Wildlife to control this. https://www.inaturalist.org/observations/19638889
