1. NORMANOCH ASSOCIATION AQUATIC PLANT MANAGEMENT PLAN 2015

2. HARVESTING HERBICIDE  Harvesting partially removes aquatic weed mass but only small amount of Phosphorus and Nitrogen.  Alleviates boating lane obstruction in Stehr and Myrtle channels in response to complaints  Causes silt disruption due to turbulence in shallow areas causing spread of nutrients.  Is inefficient and costly =/>$10,000/year  Fragmentation and loose cuttings have spread Eurasian Water Milfoil into main body of the lake.  Most lakes are abandoning harvesting for above reasons.  Use of herbicides is a first for NA in managing aquatic weeds  Unknown numbers of water consumers - but none along Stehr tract –they have their own water supply system  Emotional and strong feelings of some members against its use. Must help them understand.  Cost effective – systemic will have up to a 3 year effectiveness saving $20,000 in Sterh Tract  Sonar (Fluridone) for Stehr Tract  Clipper for EWM in selected lake areas.  Consultant 100% supportive of plan since plan is < 10% of lake area.  Herbicides used widely at other lakes Owassa, Kittitiny, Mohawk, Mountain.  Owassa has water consumers also.  Totally biodegrades

3. EWM INFESTATION AREAS Stehr Tract  Approximate area to apply herbicide 25 acres.  Very dense EWM between Alfano’s and entrance to Blue Ribbon  Some areas of Stehr Tract will be exposed in fall drawdown but not area of EWM.  Suitable for Systemic type (Sonar) Lake Areas  North Shore –about 3 acres  Causeway Cove – about 6 acres  Dam Cove – about 4 acres  West Shore – about 2 acres  Total area approx. 15 acres  Suitable for Contact type (Clipper)

5. RECOMMENDATION 1  Notify members by letter  Invite to a meeting in February or March to ask questions  Test Treat the 25 acre Sterh Tract area with a systemic product called Sonar.  Two 15 ppb treatments over 2 week period.  Only irrigation restriction  Will be effective control for 2-3 years  Minimize or eliminate harvesting.  Lake drawdown will help shallower areas.

6. RECOMMENDATION 2  Apply a contact product, Clipper to control EWM in selected areas in the lake proper, i.e. the North Shore, West Shore, Causeway, or Dam coves in heavily infested areas.  This will provide some degree of control over EWM.  A survey in July will provide valuable information for a future decision making in 2016.  Clipper is a contact product that has takes very little time (2 days) to knock down the weeds.  It too has no water use restrictions except irrigation.  Clipper is a proven effective and fast acting control of EWM

7. BUDGET COSTS FOR CONTROLLING EWM  Sonar for Stehr Tract  $12,000 for 25 Acres  Total Cost for both treatments$22,000  Clipper for Spot treatment  $690/acre  $10,000 for 15 acres
