Algae blooms possible
During the summer, Lake Byllesby Reservoir is subject to algae blooms. They can occur at any time throughout the season and depend of many factors. These algae blooms can contain blue-green algae, which can be harmful to humans and pets.
When the algae is present in the lake, we suggest the following:
- Do not swim, waterski, or tube if the water looks like spilled green paint or pea soup
- Avoid swallowing water and watch small children and pets who may ingest water
- Rinse off with clean water after swimming
- Stay away from areas of scum when boating
