SAN FRANCISCO (KCBS RADIO) – Harmful algae blooms have shown up throughout Discovery Bay, according to a recently submitted report to the Water Resources Control Board's HAB Incidents Reports Map.

Last Wednesday, a report was filed warning people not to go into the water, to "stay away from algae and scum in the water," said the report.

The advisory also recommended people to not let their pets or children near the water, "drink the water, or eat scum on the shore," said the report.

The advisory is bay-wide, and people are also advised not to eat any shellfish from this water.

Earlier this month, the Regional Water Quality Control Board sampled the water and the results showed harmful algae blooms present, according to a release issued by Contra Costa County Health Services.

The algae produces cyanotoxins, which can be harmful.

One segment of the area, Reclamation District 800, is conducting a study in Willow Lake beginning in Mid-May through August on harmful algae in the water, in an effort to try and reduce the portion of algae present.
