(KNZA)--A public health advisory for a local lake has been upgraded, while an advisory has been issued for another local lake due to the presence of blue-green algae.

The Kansas Department of Health and Environment said in a news release Thursday that Holton's Elk Horn Lake has been upgraded from "watch to "warning" status.

KDHE also said the Hiawatha City Lake remains under " warning" status.

The release said a health watch has been issued for the Atchison County Lake.

12 lakes in the state are currently under warnings, with 11 under watches.

When a warning is issued, KDHE says water contact should be avoided.

Fish may be eaten if they are rinsed with clean water. However, only the fillet portion should be consumed and all other parts discarded.

For lakes under watch status, people are encouraged to avoid areas of algae accumulation, and keeps pets and livestock away from the water.

You should clean fish well with potable water and eat only the fillet portion.
