T’is the season for raking leaves, and we can assure you that our lake is no happier than any of us to have to absorb decaying leaves. Cupsaw really doesn’t need more nutrient to feed next year’s weed and algae growth. We can all help:
- Please keep leaves away from our storm drains and adjacent curbs. (If you have a landscaper, ask them to pick up curbside leaves by drains.) Rain washes leaves into the storm drains, clogging them. Decayed leaves wash into the storm drains and it all ends up in the lake.
- Don’t compost leaves close to the lake or any of the streams that empty into the lake. Same principal: We don’t need these leaves adding to the lakes biomass.
You may have noticed one step taken this fall to protect our lake water quality. The town dredged the settling pond at 234 Cupsaw Drive (Northeast end of the lake). This helps reduce the amount of nutrient reaching the lake from that stream, which has tested high in phosphorous. Our test team checks nine inlets regularly so that can address problem areas.
Thanks again for your cooperation.
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.
September 2018 General Membership Meeting – Monday, 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.
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.
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.

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.
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.
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.
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.
