CYANOBACTERIA WARNING REISSUED – AUGUST 12, 2024

Hello PLA Community,

Unfortunately the Cyanobacteria Warning has been reissued for Province Lake.  This is based on bloom reports and pictures shared over the weekend and not a new sampling.  They will be back on Friday to resample.  See official announcement below.

Regards,
The PLA

Hi All,

I apologize for the confusion, but we will be “re-opening” the cyanobacteria warning on Province Lake. Over the weekend, several people reported increased bloom conditions. Please see the pictures attached. Bloom conditions have reappeared along the south shoreline on Bonnyman Road. We are reopening the warning without additional sampling because we already know there is cyanobacteria in the system (sampling on Friday indicated continued cyanobacteria presence below bloom densities), and from the pictures it is evident that the density will be above the recreational use guideline. Please let me know if you have any questions. We will plan to resample again on 8/16. Please post signs again at public access points.

WaterbodyProvince Lake, Effingham and Wakefield
StatusWARNING
Issued8/2/2024 – reissued 8/12
Bloom Description (picture attached)Thick green clouds of material and light green films on surface of water.
Cyanobacteria TaxaDolichospermum
Cyanobacteria Density (cells/mL)535,000
NotesBloom appeared again 8/10 and 8/11 at several locations along the south shoreline.

Warnings are issued when cell counts exceed 70,000 cells/mL. NHDES advises lake users to not wade or swim in or near the vicinity of a bloom during a warning. Please also keep pets and livestock out. The warning is intended as a precautionary measure for short term exposure. Please see our newly updated FAQs for more information.

Warnings remain active until the bloom subsides. I will reach out to you before then for updates. If you have information on where accumulated material is being observed at that time, please let us know to guide our sampling efforts. You can also see warning details on the Health Swimming Mapper.

To the health officer or other official responsible for posting signs, please post cyanobacteria warning signs at all public access points. We have a new version of the sign available for use. Please feel free to print and use this new sign until we can deliver a laminated version to you. Please let us know how many and the address to drop off new signs if you are interested. NHDES will be in contact again once the warning is lifted and signs can be removed.

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 to be directly included on future communications from NHDES. If you prefer to no longer receive these sampling updates, simply respond, and indicate “unsubscribe”.

CYANOBACTERIA WARNING REMOVED – AUGUST 9, 2024

Hi All,

The Warning for Province Lake has been lifted.  See official notice below.  The signs will be coming down shortly.  However, as we all know, blooms can come and go quickly, so please keep your eyes open.  Have a great weekend.

Hi All,

The cyanobacteria warning at your lake has been removed, please see below for details.

WaterbodyProvince Lake, Effingham and Wakefield
StatusWARNING REMOVED
Issued8/2/2024
Removed8/9/2024
NotesFour samples were reviewed, three from Bonnyman Rd, and one from Sunset Rd. All had densities ranging from 6,867 – 11,200 cells/mL Dolichospermum. The rain may have suppressed densities, but community members reported that water conditions had improved from last week. Please let us know if bloom conditions appear again next week.

While the bloom accumulation has dissipated, NHDES advises that lake-goers look out for discoloration or surface accumulations in the future. Please continue to monitor your individual shoreline for changing conditions.

The cyanobacteria warning signs can now be removed from public access points.

Thank you all for your communication. If you see cyanobacteria in the future, please report it through the bloom report form

CYANOBACTERIA TREATMENT OPTIONS DISCUSSION FOR ANNUAL MEETING 2024

As you know, the annual meeting will have a couple of guest speakers that are experts on ways to help mitigate cyanobacteria blooms. In addition, you should be aware that the board created a subcommittee in the fall of 2023 to look into possible treatment options for when there is a bloom. The subcommittee primarily used the list of options from the US EPA website and dug deeper into options that, at first glance, seem possible for Province Lake.

The attached table is a summary of that work. The first 3 columns are directly from the EPA website. The last three are case studies, additional information and Province Lake potential. We thought it would be good to allow you to review this before the meeting and therefore we are providing this to you now. The long and short of this is that there is no “silver bullet”. Any option would require approval and permitting from NH DES, and we are not sure what involvement would be required of Maine DEP. Most are very expensive, and to obtain funding through grants etc. will not be quick. The best and longest term solution is to limit the nutrient load into the lake. This will be the primary focus of the guest speakers. After the speakers, there will be some time to talk about the table attached.

As a reminder, the meeting will take place on Saturday July 27 at Edge Lake Farm at the Golf Course. Social meeting starts at 9:30, with the actual meeting beginning at 10. We hope to see you there.

BOARD NOMINEE’S AND BYLAW UPDATE FOR VOTE AT ANNUAL MEETING

We wanted to share information with all members who are interested in voting at the annual meeting. There will be at least three items that will require a vote that we felt you should review in advance of the meeting. We will be approving the minutes from last year’s (2023) meeting and you can read those on our website under “News & Important Info” then “PLA Annual Meeting Minutes”. We also will be voting in new officers and directors and you can read their bios in the attached pdf file. Finally, there is a very minor change to the bylaws where we added a function that the Treasurer does. You can see that edit in the pdf below and it is track changes, so the edit is highlighted in Red.

We hope you are enjoying the summer and we hope to see you at the annual meeting on July 27th at 9:30am at Edge Lake Farm.

CYANOBACTERIA ADVISORY REMAINS – JUNE 18, 2024

NH DES performed sampling at the lake on Tuesday, June 18th.

Unfortunately, visible blooms were noted along Bonnyman Road, and sampled concentrations were higher than the state limit … official notice below.

Hi All,

The cyanobacteria warning remains at your lake, please see below for details.

WaterbodyProvince Lake, Effingham and Wakefield
StatusWARNING (ADVISORY) remains
Issued6/4/2024

Cyanobacteria TaxaDolichospermum
Cyanobacteria Density (cells/mL)4,420,000
NotesThe cyanobacteria density continues to exceed the state limit of 70,000 cell/mL, so the warning will remain active. Four other samples were collected, but not reviewed due to program constraints. Severe bloom conditions were observed along all sample sites on Bonnyman Road. No bloom was observed on the North shoreline along Bailey Road.

Please keep signs posted at public access points. NHDES will arrange for sampling again next week. Warning details can also be found on the Healthy Swimming Mapper. If you click on the warning symbol, you can see our most recent sampling date. When warnings are lifted, the red symbol for the waterbody will no longer be on the map.

Two locations had severe bloom accumulations (reported above, and 483,750 cells/mL), while the other three had low cyanobacteria presence (1,200 – 9,800 cells/mL). The high bloom densities were observed on the south shoreline. A sample from the north shoreline had the lowest cyanobacteria density.

Please keep signs posted at public access points. NHDES will arrange for sampling again next week. Warning details can also be found on the Healthy Swimming Mapper.

CYANOBACTERIA BLOOMS OBSERVED – JUNE 3, 2024

Hi Province Lake Community,

Unfortunately, several blooms have been observed around the lake over the last couple days, including this morning.  This has been reported to NH DES and they are analyzing the samples to determine if the signs need to go up or not.  We just wanted to get the message out that blooms have been observed and that we all should remain vigilant.  Attached is a picture from this morning. 

Once we hear more from NH DES, we will communicate that to you.  Again, if you see something like the picture attached, stay out and especially keep children and pets out.

Regards,

The PLA
