Lake Update

Its been 6 weeks since we were closed based on a NJDEP HAB (harmful; algal bloom) test.  We were asked not to retest until the algae bloom completely dissipated.  This bloom was persistent because of repeated heavy rain events washing new nutrients into the lake throughout September.  Now that the lake is back to normal, we’ve asked the DEP to retest and we expect to be cleared by the NJ DoH soon.  

Tests for HABs is a new thing.  We’ve always tested well for the weekly bacteria tests the state requires.  But HAB tests will become more frequent, so we have to take aggressive measures to reduce the nutrients coming into our lake, e.g., support of a town septic pumping ordinance and filtering at those inlets which we have tested to be our worst source of phosphorus.  Our members can also help by pumping septic tanks every three years, using bio friendly washing liquids (Seventh Generation and Natures Promise), using less lawn fertilizer and mulch, and keeping storm drains clear.

Thanks in advance for your cooperation.

General Membership Meeting

September 2018 General Membership MeetingMonday, Sept. 24 at 7:00pm @ CLIA Clubhouse

All CLIA members are welcome to attend.

Remember, this is your lake and this meeting is an opportunity to stay informed with matters surrounding this community and to make your voices heard.

If you are unable to attend, there is always the option to reach out to committee members via Contact Us Page.

Lake Closure

Cupsaw Lake is closed for swimming and wading due to a harmful algae bloom (HAB) with high levels of cyanobacteria in a DEP test taken this week. We will need two clean tests before we are permitted to reopen. The next test is scheduled for next Tuesday. The beach area will remain open and boating is permitted, but please exercise caution to avoid water contact.

Love Your Lake

The Cupsaw Environmental Committee invites the general membership to a 90 minute “love your lake” meeting on Tues, July 24th 7:30pm at the clubhouse. We will share our activities with aeration, lake treatments including blue dye and alum, lake testing, watershed management, and goose control. All are invited; we welcome your ideas.

Please direct questions to Alan Fedeli or Tom Conway. Thank you.

Environment Committee Update

Benefit of Regular Septic Pumping
Scientists at the leading NJ Lake Management company report that with regular septic pumping we can reduce the nutrients flowing into our lake by 20 to 30%.  What a difference that would make to the health of Cupsaw Lake.  As a rule, we should be pumping our septics at least every three years.  Please help.  Spring is a good time to get this done before we allow runoff to add nutrients to our lake that cause excessive growth of weeds and algae. 

 
Aeration Upgrade
We and several lake management experts have concluded that our aeration system is undersized.  As a result, the benefits of improved dissolved oxygen are offset by the mixing of nutrient rich bottom water in summer months.  We are going to add diffusers to the deep end to correct this problem.  We will test to determine the benefit of this upgrade.
 
Blue Dye
The use of blue dye was so successful last August that we plan to use it again this year.  In fact we plan to apply it in the Spring and then have a booster shot in the Summer.  The purpose is to block the UV rays to slow the growth of weeds and algae.  It is food grade, thus safe for our swimmers.

On behalf of the Dam Committee…

Please DO NOT disturb the rocks on the face of the dam. They are there to protect the dam from erosion. 

They are a specific type of rock which the lake has to purchase at great expense.  Throwing them on the ice is not acceptable.

Letter from CLIA Nov 22, 2017

Dear Cupsaw Members,

As 2017 comes to an end, the CLIA Board would like to thank all the volunteers, groups, committees, and members who gave so generously of their time and expertise. One of our most important and final projects for this year, the resurfacing of the deep end wall by the diving area, was partially funded by WAA (Women’s Athletic Association). A big thank you to that organization! Please continue to check the website and email newsletters for fun winter activities.

We wish you all “Happy Holidays and a Happy and Healthy New Year!”

The CLIA Board
