Ten North Umpqua Hydroelectric Project impoundments were surveyed for aquatic invasive species during the summer of 2012. One non-native submersed aquatic vegetation species (Potamogeton crispus) and one non-native snail species (Radix auricularia) was detected. No crayfish or mussel veligers were collected and no non-native zooplankton species were encountered.
