Hi Province Lake Community,

NH DES sampled the lake today and got a reading that is still above the state limit, so the advisory will remain active and the signs will remain up.  We will keep you posted when they sample again.  Their official announcement is below ..



Hi All,

Province Lake was resampled today, 11 October 2023. The cyanobacteria density continues to exceed the state limit of 70,000 cell/mL, so the advisory will remain active. The highest observed density was 122,000 cells/mL with other samples collected ranging from 3,667 cells/mL to 41,560 cells/mL. Please keep signs posted at public access points. NHDES will arrange for sampling again in the next two weeks.

If people ask for updates on the current cyanobacteria advisory status, please direct them to the Healthy Swimming Mapper. If you click on the advisory symbol, you can see our most recent sampling date. When advisories are lifted, the red symbol for the waterbody will no longer be on the map. 

Please forward this email to other residents / community members who need this information. If they would like to be added to the email distribution list, please have them sign up through this form to be directly included on future communications from NHDES. If you prefer to no longer receive these sampling updates, simply respond, and indicate “unsubscribe”.

Thank you,
