2021 Oregon Lakes Association Online Seminar Series

Wednesday Nov 3 (2:30-5pm),  Nov 10 (2:30-5pm) and Dec 1 (3-5pm)

Online Zoom meetings 

The Oregon Lakes Association will be holding our Annual Lakes Conference as a series of online, Wednesday afternoon sessions this fall. Session topics are: 

  • CyanoHAB monitoring and detection. Wednesday, November 3rd from 2:30-5 pm
  • Lake physiology and management and OLA Business Meeting. Wednesday, November 10th from 2:30-5 pm
  • Our beautiful lakes: past and present. Wednesday, December 1st from 3-5 pm

Presentations will cover a wide range of topics including desert lakes, climate change, paleolimnology, remote sensing of cyanobacterial blooms, water quality modeling, and lake management. The Conference Agenda and Abstracts are available at this link.

The meeting will be a remote video conference offered through Oregon State University’s Zoom platform. Registration is free for Oregon Lakes Association members and $20 for non-members - or join OLA! Individual annual memberships cost $35. After registration, you will receive an email with instructions on how to join the Zoom meeting including a URL link, phone number, and a password. To participate you can join by computer (video or audio) or telephone. You do not need to load Zoom onto your computer; you can connect with Polycom, Cisco, or other room system if you don’t want to use the Zoom access link.

This meeting is open to anyone interested in Oregon lakes so feel free to alert colleagues or friends who may not have seen an invitation.
