“Flushing” the Lagoons

You may have noticed the lagoons being partially lowered (e.g. by 4-6 inches) and then re-filled a few days later.   The City of Alameda is performing these partial lowerings every two weeks during the summer months with the intent of increasing water turnover.     Periodically “flushing” the lagoons helps to lower the average water temperature and mitigate against algae growth.
