Some news on 5/21/09 about the invasive species curly leaf pondweed in volney from the Lake Detective Steve McComas of Bue Water Science.
From Steve McComas
to Steve P — I did some curlyleaf work on Volney a few years back. Based on lake sediment conditions, Volney sediments are not conducive to supporting heavy growth of curlyleaf pondweed. That is good news. If you were to consider harvesting, a good contractor is Rick Thompson at Midwest Weed Harvesting (Savage MN, 763-238-1012)
Costs are about $160/hr which are equivalent to $350 to $600 per acre based on how heavy curlyleaf growth is and how far the harvester has to travel to a drop-off point. The lighter the growth and the closer the drop-off area, then the lower the cost per acre.
I’ve attached a chart that shows three types of curlyleaf growth: light, moderate, and heavy. Volney has mostly light to moderate growth.
I’ve also attached a Volney Lake sediment survey. The results indicate that we would not expect long-term heavy growth of curlyleaf based on the lake sediments.
Take care,
Steve McComas

Could you recommend a contractor to do this and any guess as to the cost.Thank you.Steve P, Treasurer Lake Volney Assn.
