| Impact Description | Nitellopsis obtusa has been associated with increased water clarity in inland lakes, which could in part be due to their association with zebra mussels (Dreissena polymorpha) as a favored substrate. In spite of increased water clarity from the mussels, the dense growth of N. obtusa actually reduces light availability for other submersed flora. |
