Lycott Environmental | AUGUST 4, 2014

SPECIAL NOTCE: The lake has not been chemically treated yet this year due to a delay receiving our permit from the CT DEEP. For years, copper-based products have been used to treat the algae, but the DEEP fisheries department held up the permit for the copper-based chemicals this year due to concerns about herring populations below the dam and trout populations within the lake. We were granted the permit last week but will be using a peroxide-based chemical as an alternative for the algae treatment. Further investigation into the new DEEP policy and assessment of the effectiveness and feasibility of the perixode-based chemical will be conducted. LH members will be updated in the coming months.

Of note, the plant growth in the lake is different than recent years. Because the algae growth is lighter than usual, the water is very clear, allowing light to easily penetrate shallow and mid-depth areas promoting weed growth. Additionally, it’s possible that with less competition from the algae, the weeds have more nutients (phosporous & nitrogen) available to fuel growth and abundance.

Lycott Environmental is scheduled for MONDAY, AUGUST 4, 2014 to perform the below water quality management items:

– Survey current weed and algae growth throughout lake.
– Manual removal or herbicide application as needed for invasive and nuisance aquatic weeds in swim/recreational areas.
– Algaecide application to reduce nuisance filamentous algae (green/brown slime on bottom).
– Algaecide application for microscopic algae as needed (floating algae that causes green water).
– Water sampling for water quality monitoring.

Lycott typically performs the work using a small motor boat launched from Beach 6.

LAKE USAGE
Lycott posts chemical application notifications (yellow 8.5″ x 11″ paper) at applicable beaches during or immediately after all chemical treatments. The notifications contain details of water usage restrictions which are generally minimally interruptive to lake recreation.

PLEASE keep an eye out for the posted notifications and adhere to any noted usage restrictions. If chemicals are applied directly in a swim area, it is advised to remain out of the water in that area for one hour.

HOW CAN YOU HELP?
**Feeding your lawn feeds the weeds and algae in the lake. Minimize or eliminate lawn fertilizers. As an alternative, consider using organic fertilizers with low or no phosphorous (the middle number is phosphorous, ex., 18-0-4).

**Manually remove nuisance aquatic weeds and filamentous algae from near-shore swim areas.

Please contact your District Rep with any questions or concerns.
