Attached is a map of populations of Large leaf pondweed (Potamogeton amplifolius) and also Filamentous algae found at West Hill Pond during our June 21st, 2018 aquatic plant survey. The below photos show what the filamentous algae looks like. The second photo is particularly bad and is from the spot marked with the “severe filamentous algae” green triangle. It’s also one of the spots where we had relatively high nitrate nitrogen during our seepage survey. We are looking into this spot more carefully now as we’ve found for two years now that it has large filamentous algae covering.

Update September 25th – We have received a preliminary engineering plan which describes the repairs to the gate house area we have been discussing. The repairs include replacing the gate house with an on-grade solution which will not limit future Perkins road snow plowing activity. Estimates presented for this work generated by our engineering firm agree with the lower side of our own preliminary estimation assuming the towns still help by providing some supplies (sandbags), the machinery and operators as planned. The expected total budget for engineering and repairs remains $80,000 funding for which has been met.
Water level is at the maximum drop expected, about four feet from the mean normal water level. The photos show that it may still be possible to launch hand-carried craft such as kayak or canoe to the water over the ramp. It is unlikley that a trailer launched vessel could be successfully launched.
Work is proceeding on the draft permit plans [4mb] which will serve as the basis for the construction plans when approved.

Donations go to help restore the dam at West Hill Pond.
West Hill Pond is a natural glacial lake with water level raised by the addition of a dam located at the lake’s north end. difference between subject matter and thesis follow url how much time for cialis to work go here go here https://academicminute.org/paraphrasing/aircraft-maintenance-planner-resume/3/ essay essay writing services review creative writing description of happiness doses lamictal comes in how do i write a letter on my ipad pro cover letter essay high quality papers call for paper in management journals viagra com bebida faz mal ways to make your paper longer essay proposal example university thesis statement outline essay free online research articles https://www.aestheticscienceinstitute.edu/medical/media-pastilla-levitra/100/ paul mccartney taking viagra animals life essay help with top university essay follow url answers help with homework please viagra jacksonville teenage pregnancy essay online homework service viagra dose for bph enter viagra ice cream where to buy how come viagra didnt work how much sildenafil to take The dam raises the lake level about nine feet. So imagine the impact of no dam. Water would retreat to a distance from the current shore virtually inaccessible to existing docks and boat launch ramps. With limited boat access, there would be significant impact to recreation use and property values. In fact, the purchase of dam and water rights back in 1964 was seen as a means of protecting shorefront owners from capricious summer withdrawals impacting lake water level. Before the West Hill Pond Association (WHPA) acquired water rights the water was often drawn down in summer to where one could walk out one hundred and fifty feet or more from shore before encountering water.
The State of CT began a process several years ago of evaluating all dam impounded water bodies in the state of Connecticut for safety and risk impact. West Hill Pond, on account of its dam and spillway structure, and potential zone of inundation (downstream flooding) was deemed to require an enhanced Emergency Action Plan which is an updated and far more extensive version of our existing Emergency Operations Plan developed and certified by Professional Engineers. This was to evaluate to potential zone of inundation and specific properties at risk should there be a catastrophic event. In addition, we were required to complete an engineering evaluation of the dam infrastructure and provide details on the structure itself, and operability during a major (100 year) storm event. It was during this evaluation that we identified repairs and changes the WHPA would like to perform to improve the long term viability of the dam.

In order to make the identified repairs, the plan is to lower the lake between 3 and 5 feet by October 1, 2017. This compares to a planned 2017 drawdown of 3 feet as defined by the WHPA water level policy. This greater water level drop is also considerably earlier than the typical October water level drop. Stakeholders are advised they should be prepared to remove boats and floating docks by the end of September. With this schedule, work can commence and be completed before the first frost.
Initial cost estimates for the repairs run from $50-$80,000. Both towns that straddle the lake, Barkhamsted and New Hartford, have agreed to provide highway crews and materials for the area surrounding the project and are being cooperative. Unfortunately, no State of Connecticut funding can be expected. Accordingly, the bulk of the financial burden for reconstruction of the dam will be borne by those of us who live on or enjoy the use of our lake. This is why your financial help to repair the dam is essential.
Please make a contribution today to preserve our treasured lake. Make your CHECK payable to West Hill Pond Association — which is a Charitable Nonprofit Organization – 501(c)(3) — contributions are tax deductible as per IRS guidelines.

Internal Loading versus External Loading Dilemma
The lake phosphorus loading model used a common internal release rate of 1mg/m2/day to estimate 60kg/yr TP load. However, that release rate needs to be refined to better reflect West Hill Pond.
External nutrient load from appears to be different in base-flow vs. stormwater flows. Stormwater flows had lower phosphorus and nitrate than the base-flow values suggesting that largest contribution of water to base-flows of streams is from septic systems. These concentrations appear to be diluted by rainwater, suggesting that stormwater runoff drains minor impervious areas and is collecting only minimal nutrients from these surfaces.
o Continued monitoring of streams during both base-flows and storm events is recommended.
o A perimeter study of seepage water during the fullest extent of winter drawdown is recommended.
o A Very Near Shore Conductivity Sweep during late summer is suggested.
A summer aquatic plant survey was completed by the West Hill Pond Association’s Limnologist in July. We hired an aquatic plant mitigation team which spent 2-1/2 days removing the targeted aquatic plant communities. (more…)
Those of you that follow lake water level management know that this fall/winter (2016/17) is the “big drop” – an extra foot of drop (three feet as opposed to two feet) – which happens just once every five years. There have already been Inland Wetland Commission applications submitted (and approved) for work by homeowners set to be performed this fall. Water level management begins in October with the goal of reaching the full drop by October 15th. (more…)

Public Hearing Town of New Hartford
Amendments to the Zoning Regulations
In 2015 the Town of New Hartford updated its POCD which among many other things included a section recognizing the need to “Protect West Hill Pond.” The Plan set forth several action steps for doing so. Earlier this year the town held an open “Round Table” forum to determine the most urgent item in the POCD. Protecting West Hill Pond came out on top. As a result the town has developed proposed zoning amendments – special protections for the R-4 zone (West Hill Pond watershed) alone – which are to be presented at the July 13th public hearing.
A recent article in the Danbury News Times about the issues facing Candlewood Lake from blue-green algae had us thinking about the blue-green algae sampled at West Hill Pond last summer.
Blue green algae – also known as Cyanobacteria – has become a visible concern in recent years to lake managers throughout the world. Cyanobacteria are prokaryotes rich in proteins that obtain their energy via photosynthesis. Their high protein makes them less attractive to the Zooplankton grazers found in freshwater lakes that prefer the cellulose rich phytoplankton (Eukaryotes). This lack of predation on Cyanobacteria gives it a selective advantage over other phytoplankton. Today, Cyanobacteria grabs headlines not because of its creating life-enabling oxygen, but for its more insidious side. Certain Cyanobacteria are the source of cyanotoxins implicated in neurodegenerative diseases such as Lou Gehrig’s, Alzheimer’s and Parkinson’s disease. Cyanotoxins are a much broader category than just neurotoxins, and include hepatotoxins, endotoxins and cytotoxins as well. Managing the lake to limit the possibilities for large Cyanobacteria blooms is one of our highest priorities. (more…)
