NOTICE (11-03-2019) -- KINGDOM DAM REPAIR AND RECENT STORM
Repair work on Kingdom Dam was completed on October 30th but a storm bringing severe rains (4+ inches) and extremely high winds soon followed, so the lake rose VERY rapidly and water is now well over spillway. Luckily, the water level of the lake was low when the rain came (since it was lowered to allow for the repairs) and so shoreline damage was minimal. Unfortunately, however, many of the dirt and gravel roads around the lake were also impacted by the rain, suffering mild to severe erosion damage. Below is a short video of the dam, showing water flow level; above are two photos -- one showing water road erosion at the end of Kingdom Dam road, near the dam; the second is of Branch Brook (a segment of Brandy Brook).

SUMMER 2019 - Record of Events
ROAD CLEANUP --On Saturday, June 22, 2019, at 9 a.m. around two dozen Association members came together to help clean up more than 3 miles of Lincoln Pond Road extending eastward and westward from Lincoln Pond. The large number of volunteers helped us complete the task in a little more than an hour. That might be a new record! Thanks to all who helped!!!!
ANNUAL MEMBERSHIP MEETING --
Our annual meeting was held on Saturday, July 20, 2019 at the Sienkiewicz camp (39 Lower Pond Way). We had a fine turnout with around 40 attendees. The minutes of the meeting are available here: LPA Meeting Minutes 7-20-19[FINAL].pdf
ASSOCIATION PICNIC -- On Saturday, August 10, 2019 several dozen Association members and their families came together for our annual picnic. A good time was had by all -- and the rains held back!
News and Announcements (2018-2019)
* Lake Champlain Basin Program grant for invasive plant survey and management program (5-25-2019 update). We were awarded up to $13,800 to help us develop a lake management plan and to support a public educational effort focusing on preventing the spread of aquatic invasive plants. We've initiated our public education efforts by building and installing invasive spread prevention leaflets in outdoor literature boxes near formal and informal boat launch sites. We have placeed a total of four information boxes around the Pond (see photo to the left). We have also hired a subcontractor, Northeast Aqiuatic Research, to develop a comprehensive aquatic plant survey and a long-term management plan for controlling our milfoil beds; they will begin their work shortly.
Their final report and recommendations, anticipated in the late fall or early winter, will allow us to begin our milfoil control work; it will also put us in a better position to obtain larger grants to assist us in implementing our subcontractor's recommendations.
* Invasive Plant Tracking Survey (10-5-2019 update). We began working with the APA (Adirondack Park Agency) and APIPP (Adirondack Park Invasive Plant Program) on an Invasive Plant (milfoil) Tracking Survey
to supplement and complement our Lake management plan (see above). Training sessions were scheduled, Association members were trained, and we completed our tracking over several days in August and September. We expect the results of our work -- the tracking data and map -- will be ready in November (we'll post it here when we receive it from APIPP.
* Essex DPW Road and Related Work Plans (10/5/2019 opdate):
DPW was unable to complete repair work last November on the road erosion caused by storm water flowage at the intersections of Lincoln Pond Road and both Twin Brooks and
Francis Myers Drive. They placed us on their calendar and finally completed the work in July.
We obtained all the permits necessary -- including the permit from Essex DPW -- to allow us to conduct hand dredging of sand deposits filling in the south side of the causeway bridge/culvert. We hoped to schedule the work for late summer or early fall, when we anticipated the water level would be substantially lower-- but the water level remained quite high so we might put off the work till next year rather than take it on this fall.
Over the 2018/2019 winter, we began discussions with the Essex County DPW toward ultimate replacement of the culvert bridge with a higher, wider, and deeper one across the causeway. They agred that the bridge should be widened to around 40 feet to permit free flowage of waters from the upper to the lower pond (what they expect DEC will require). We explored possible designs, but without external grant funding, this job will have to wait till the normal culvert life replacement date -- around the year 2038. If undertaken today, the cost is expected to be around $700,000. BUT if federal or state grant funding could be obtained, we would be able to fast-track the project. We are now exploring possible grant sources.
* Kingdom Dam/Water Level Issue (UPDATED 10/5/2019): The Pond water level is still high - at around spillway level (which is now higher than the former-- pre-dam reconstuction -- spillway height).
11/15/2018] The curbs on the notch section were not installed properly and DEC is contacting the contractor to address this problem; the slabs were not joined to their concrete base correctly and water seepage is occuring below them. Nonetheless, the lake level is now quite high as a result of recent rains and snow.
[9/17/2018] From Tom Lincoln (9/11): "Concrete curbs will be delivered this Thursday [9/13] and they expect to be installing them on Monday 9/17 weather permitting." Work has begun. Lake level has been lowered. Culvert bridge water level very low and boat passage is restricted.
We will post photos once the work has been completed.
[9/10/2018]: Update from DEC engineer Tom Lincoln: "With the rain in the forecast, the contractor will not be back on site until Thursday [9/13] at the earliest. Depending on the storm totals, they may not be on site until next week.
We are targeting 4” below the notch for a pond level during the work. Once complete, and after the water is flowing over the spillway again, things will be entirely run of river.
We will pass along updates as we get them."
[8/28/2018]: From DEC engineer Tom Lincoln: "I was told today that the target date is September 10th to begin work but that could shift. Our DEC biologists have asked that all drawdown work be done by 10/01. It sounds like we are on track for that as the work should proceed fairly quickly. The contractor should only need the water a foot or less below the notch. I am not sure roughly how low it is now, but boaters should plan accordingly after Labor Day for lower water. After that it will be up to Mother Nature to get the water back to the notch level while a baseflow of water is maintained downstream."
[May, 2018]: Here is a selection from an early May 2018 correspondence from DEC's managing engineer, Tom Lincoln, on the Kingdom Dam/Water level issue (on correcting the dam elevation and raising the water level height of the lake):
"The modification to the dam is the installation of concrete curbs across the spillway crest. The spillway portion raise is five inches and the notch raise is seven inches. I made a pitch to our staff about reducing the notch depth, and they agreed it would be acceptable. That is why the notch raise is greater than the rest of the spillway. That should improve things during unusually dry times where there will be a higher pond surface.Clough Harbor was having difficulty getting a contractor to do the work but has reached out to other groups that have done good work with them in the past. DEC Fisheries and Wetland staff gave permissible dates of mid-June to September 30th to complete the work. Given that the water has to be below the notch elevation to install the curb, we asked Clough Harbor to set up construction to occur after Labor Day. Depending on the weather conditions, ideally the water would be lowered beginning just after Labor Day weekend. This would avoid impacts to the residents during the season.
For the 2018 season,
I was able to get the DEC staff to agree to install cinder blocks and/or sand bags to block the existing notch. That will keep the water surface as high as possible for this year at the dam. Those will be installed as the spring flows are reduced and the water is near the spillway crest.
Lastly I wanted to reiterate that the dam is still set to operate as run of river as mandated by Fisheries staff during the permitting phase. There will not be different winter and summer elevations for the pond."
FOLLOW UP -- The cinder blocks and sand bags mentioned above have been installed. Corrective work on the Dam will take place after Labor Day this year (2018). Tom Lincoln recently (8/1/2018) sent the following construction plans for the entire Dam project. He noted that the set of plans is "from the end of the construction as the dam now sits. There will be some elevations that are corrected in a future set after the work is done this fall, but the alignment and configuration of the dam is accurate."

* REPORT ON JULY 31, 2018 SPECIAL MILFOIL/INVASIVE PLANT MEETING: Leigh Walrath from the APA and Tim Post from DEC -- with Gerry Zahavi and Wayne Johnson -- met to tour Lincoln Pond on the morning of July 31 to evaluate the extent of our Milfoil infestation. They then made a presentation to Pond Association members at 10:15 AM, discussing different approaches to milfoil control, grant $ sources, state regulations, and long term management recommendations. The presentation took place at Camp 6, 39 Lower Pond Way (Sienkiewicz's camp). Here is a copy of the powerpoint presentation made by Leigh Walrath: Lincoln Pond Presentation.pdf
