The lake was surveyed once again on June 21. Rich and I were on the boat during the trip around the lake and only a few milfoil plants were spotted on the north end. These were treated. No phragmites plants were observed.
Due to some lake owners’ concerns about having “soft” sand, PLM tried to take muck samples to determine how much, if any, organic material is covered under the top layer of sand. Organic material is a “fertilizer” for plant growth. They were unable to take a valid sample due to excess sand and minimal other material. We are not recommending muck pellets until we get a better analysis of the sediment. If your sand gets softer and mushier the deeper you walk out into the lake, you may be able to make it firmer by raking. This helps in several ways – it turns over the sand and releases any organic material which then dissipates, it reduces your plant growth, and it reduces the snail and clam population. I found it worked quite well for me and firmed up the sand in deeper water.
