– The state has posted advisories cautioning Iowans to stay away from 11 state park beaches this summer due to toxic blue-green algae blooms.

Residents with homes along the shore of Cazenovia Lake should watch for the presence of additional blue-green algae blooms.

The warmer weather is flawless for a day on or in the lake, but officials are warning of risky blue-green algae returning.

Blue-green algae (cynobacteria) are naturally present in freshwater lakes, ponds and streams in low numbers with no visible blooms.

People and pets should not swim in surface water that is discolored or has surface scum. A 2012 fish kill in Mississquoi Bay was caused by algae, and poor water quality in St. Albans Bay last summer was part of a statewide debate this spring on water quality.

Exposure to the substance can lead to illness, with side effects that may include nausea, vomiting, diarrhea, skin or throat irritation, allergic reactions or breathing difficulties. A low alert means that shoreline areas have the algae that produce toxins, but are below levels of concern. If contact does occur, wash with soap and water or rinse thoroughly with clean water to remove algae.

Avoid bathing, showering, or washing dishes in untreated surface water that is experiencing an algae bloom.
