Lake Weeders Digest (LWD) offers a wealth of information for those seeking new and innovative ways to address problematic aquatic plant issues such as milfoil, hydrilla, curly leaf pond weed and sediment or lake muck removal. LWD is also researching new invasive issues such as snails and zebra mussels. Their products offer much more than just lake rakes, under water weed cutters, and lake muck removal tools. They provide resources and education to arm the lakeshore owner with better techniques. Send an email Lake Weeders Digest.
I particularly like a page of their site that addresses beaches and how to use procedures other than truckloads of sand to create an appealing swimming area.
