Boards are back in the dam

We hope everyone is staying healthy and faring well. Perhaps the lake can give us some peace and respite and more time to observe the migratory birds. (A wood duck has been observed in the second basin.)

As of 8 a.m. this morning (March 20), the boards are back in the dam, starting the refill.

We have been exploring calculations for flow rates based on measurements from the past (empirical approach) and on standard formula based on the width of the weir (aka spillway) and depth of water (theoretical approach).

We now have a consolidated data base with at least 10 years’ measurements that we’ll post on the LBA web site. A big thanks to Theresa O’Riorden, Conray Wharff and Dave Gray who have taken turns over the years to acquire this data.

The major 1987 Camp, Dresser & McKee Diagnostic Feasibility Study has been added to the Water Quality menu here on the LBA website.

Place your bets now as to when the lake level will over-top the boards!

Stow Con Comm hearing tonight on Eversource project

There is a Stow Conservation Commission Public Hearing tonight that may be of interest to the Lake Boon community.  It relates to the Eversource transmission line project and its effects on the lake and our wells.  While the approvals for the project are being appealed, Eversource is trying to move forward.  Both the Sudbury and Hudson Conservation Commissions are challenging many environmental aspects of this plan, with the Hudson commission reportedly mentioning the threat of contamination of Boon Lake at the EFSB hearing.  It is unknown whether the Stow Conservation Commission will challenge the plan.  Interested parties should attend tonight and make any concerns heard regarding the safety of our lake and our well water:  Wednesday, March 4, 2020 at 8:00pm, Stow Town Building, 380 Great Road, Stow

For background, the Eversource/DCR Notice of Intent, Stormwater Report and Plans, and final EFSB decision have been posted on the Stow Con Comm’s web pages here:

Update: temporary delay on replacing boards

Update: A few people have requested that we delay refilling the lake a couple of weeks, to give time for spring cleanup etc.

After checking in with the Stow Conservation Commission, we will delay putting the boards in until the week of Mar 16.  We can’t put it off later than that, per the Order of Conditions.

The Lake Boon Commission reports that now that the ice is gone, the boards will be put back into the Barton Road dam, and the lake will start to refill.

The boards will go in sometime during the week of March 2 through March 6. It will then take a few weeks, depending on rainfall, to bring the lake back up to its usual height, expected by April 1.

The net rise will be about 14 inches.

If you have any questions, please contact Dan Barstow, Lake Boon Commission, at

The Lake Boon Commission will also do a standard phosphate measurement, as part of their monitoring of lake health.

Meanwhile you can do your bit too—here is one tip to help keep the lake water cleaner and help prevent overabundance of algae and weeds.


“Healthy Lake Boon” seeks volunteers

Do you want to volunteer to help make Lake Boon a healthier place?

The Lake Boon Association is organizing a working group to review some of the data and studies about Lake Boon, recommend solutions most likely to help, work with the governing bodies, and support successful implementation.

If you want to participate in whatever way you can, please confirm to David Gray at  We’ll accept volunteers anytime, but we’d appreciate a response by February 29.

We have plenty to do, and so much appreciate everyone’s help.  Please let us know if you have special interests or expertise.  Sample tasks are:

  • Review and summarize one of the lake studies (we have about a dozen)
  • Provide expertise in lake biology (several residents have this expertise)
  • Help prepare key recommendations
  • Collect data about the lake based on test kits, observations, etc.
  • Support recommendations during Stow and Hudson meetings…

    . . . and of course, do your own part to help take care of Lake Boon!

Dave Gray, Dave Siewierski and Dan Barstow have offered to get things rolling.

We call this effort “Healthy Lake Boon”.  I’m sure we can all get on board with that goal.


Dave G., Dave S., and Dan B.

Here’s more detail:

Lake Boon is such a wonderful lake, yet it faces several health-related issues such as invasive weeds, algae blooms and possible cyano-bacteria.

Over the past few decades, several studies have analyzed the nature and challenges of the lake, and recommended possible solutions.  We have implemented several of them, such as weed treatment, controlled drawdowns and enhanced road drainage.  Yet this past year, the lake had to be closed because of possibly dangerous bacteria, and the end of season surface algae across the lake reached historic levels.

Through a combined effort of Lake Boon Commission, Lake Boon Association, Stow and Nashoba Boards of Health, Hudson and Stow Conservation Commissions et al, we want to make sure we take the best next steps to care for the lake, have improved testing and communications, and otherwise do all we can to care for our wonderful lake.  We need to do this on an integrated “total lake management” approach that will connect the multiple factors and solutions.

LBA is taking the leadership role here, to collect and review previous studies, consider key recommendations, and propose solutions to the various ruling bodies in Stow and Hudson.  This would include possible changes in treatments, improved data collection where warranted, and better communications among the various agencies and Lake Boon residents.  LBA has already started a section on the LBA web site for water quality.

Fortunately, we have a wealth of volunteers to help—residents who are ready, willing and able to help collect data, review the most useful recent lake studies, and support actions we all may need to take for better stewardship of Lake Boon.

We’d like to have initial recommendations in time for this spring . . . coming up soon!

Thanks for volunteering!
