As colder weather is upon us, the ice on the lake should always be considered as unsafe, and members should use extreme caution at all times.
Use of the lake is considered AT YOUR OWN RISK, and parents should talk to their children about ice safety. We strongly caution you against the use of motorized snow blowers on the lake.
1. You must be a member of CLIA to be on the frozen lake. All guests must be accompanied by a member with a current badge.
2. Ice Skating is at a member’s own risk. Please wait until ice is at least 4 inches thick.
3. Ice fishing restricted to area south of East Point and at least 50 feet from shoreline.
4. No power augers are permitted on the frozen lake, holes must be filled in before leaving.
5. No bonfires are allowed on the frozen lake.
6. No motorized vehicles of any kind are allowed on the frozen lake.
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.
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
The Cupsaw Environmental Committee works hard to make Cupsaw the best lake it can be. Here are just some of the efforts this group has undertaken:
- Goose Management-
- Kayak chases early in the morning to discourage geese
- Goose patrol to clean up after the occasional goose visitor in Spring
- Solar powered blinker light at lanes to discourage bedding down at night
- Back up USDA contract for removal, as a last resort. (Hasn’t been needed)
- Weed Management-
- Herbicide treatments in April and May
- “Weed rope” beyond the 3rd dock to catch dying weeds
- Canoe pick up of floating weeds around weed ropes and lanes
- Herbicide booster in June in shallow areas
- Algae Management-
- Aeration system to reduce internal phosphorus release
- Alum treatments in May and June to drop out nutrients (2016 & 2017)
- Canoe pick up of floating filamentous algae in swim areas
- Introduction of beneficial bacteria (June 2017)
- Copper Sulphate treatments in July and August as necessary
- Watershed Management
- Rain Garden (by Boy Scouts) near Volleyball court to slow erosion from courts
- Encouragement to pump septics regularly
- Encouragement to use lawn fertilizer sparingly
- Water Circulation
- Ensuring paddle wheel operation which is key to beach water quality
- Use of water movers near lanes and in deep cove areas
- Lake Testing and logging
- Weekly State testing for coliform count (always way below criteria)
- Monthly testing for algae presence by our aeration company
- Periodic testing by our own committee in our own lab
- Near daily testing and logging Secchi depth, temp, and goose sightings
- Four years of data logging to verify results of lake treatment measures
- Meetings and Outreach
- Monthly Environmental Committee Meetings
- Meetings with Erskine and Skyline environmental committees every other month
- Participation at NJ Coalition of Lake Assn’s meetings (4 times annually)
- Member of board of directors of NJ Coalition of Lake Assn’s
As a result of these efforts:
- Our State testing of beach water is regularly <10 for coliform, <200 is the requirement
- Our Secchi disk clarity has been improving year to year for 4 years
- Our lake swimmers and sailors have had fewer weeds to contend with
- We no longer contend with goose droppings on our beach
However, we can’t get too confident; we are dealing with nature. It is a lake, we will have weeds and algae, but we need to keep up with our best efforts.
