BLUE LAKE IMPROVEMENT ASSOCIATION NEWS LETTER FALL 2012

Weevil – Update

Good news for the weevils this year, bad news for the Eurasian mil-foil ( non-native ) weed. In mid July, Enviroscience was back on the lake to do their 2012 survey of the weevils activity this past year. As most of you that have visually studied the lake have seen, it has improved in most areas ( primarily the ends ) with 40 to 50% less weeds from last year according to their scientist Sarah Lomske. Both myself and board member Sue Ellen Dolan accompanied her on the survey in late July. She was pleasantly surprised at the effect the weevils have had in the two and half summers they have been with us. I reminded her that last year they added almost twice as many as were contracted, ( free of charge ) due to the extra weevil they had propagated from Idaho where they came to us from. She stated that we were probably 1 to 2 years ahead of schedule and the need for any this year was unnecessary. We will get her final survey in a few weeks to give us an in depth overview of their progress. I will post her complete survey on our website at http://www.bluelakeimprovement.org/ when received.

Weevil – Update
EnviroScience was back at Blue Lake checking on our weevils in mid-July . There was visual evidence of the weevils eating the Eurasion milfoil on both ends of the lake. The 2nd installment of weevils, approximately 10,000 per end, was also introduced to the lake in early July. EnviroScience gave us twice the amount of weevils this year as they had a lot left from their stocking program, for the same amount of money.
EnviroScience returned to the lake in early September and did a thorough survey of the lake for the summer. Jeff Townsend and Sue Ellen Dolan accompanied the two EnviroScience scientists and were pleasantly surprised to see the weevil hard at work. The west end appears to have a significant amount of weevil damage to the milfoil and was in much better shape than a year earlier. The east end showed some improvement ,especially in two areas where the weevil had made a visible impact. The east end having a denser population of milfoil will take at least 2 to 3 more years of eating on the milfoil to show real improvement. EnviroScience will give us a complete survey report some time in late October. BLIA will post it on it’s website www.bluelakeimprovement.org when we receive it. Click to read more …
