Aug 20-24; Iowa Mussel Blitz on Iowa River, Coralville Dam to Hills (weather & water permitting). This will repeat exactly the 2014 sampling which indicated a downturn in the Iowa River mussel population.  During 2005 to 2014, extreme conditions on the Iowa River (both record floods and extreme low water in winter) did seem to stress this population. The 2018 Blitz hopes to confirm both increased numbers of various mussels, and natural reproduction of re-introduced Higgins eye mussels. Volunteers are welcome, with or without mussel experience.
