(KNZA)--A public health advisory has been issued for Horton's Mission Lake due to the presence of blue-green algae.

That word came Friday in a joint release from the Kansas Department of Health and Environment in conjunction with the Kansas Department of Wildlife and Parks.

The release says the lake has been placed under " watch" status.

Two other area lakes also remain under " watch" status--the Atchison State Fishing Lake and Atchison City Lake #9.

The Atchison County Lake near Horton remains under " warning" status.

For lakes under “ warning” status, KDHE says direct contact with the water 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, KDHE says people are encouraged to avoid areas of algae accumulation and keep pets away from the water. Boating and fishing are safe. However, you should clean fish well with potable water and eat the fillet portion only
