In relatively shallow water (under about 10-feet) milfoil can completely block access to deeper water for boats and swimmers. In power boats the plant particles are sucked into coolant ducts and block them, tangle propellers and on jet-boats completely block the water intake. We had a jet-ski on the southern parts of Lake Coeur d'Alene (largest lake in Idaho) that had its water intake blocked and became unstable due to the weight of the plant material. We had to dive on the jet-ski to clear the blockage. Milfoil is a perennial and in this are it disappears in the colder months and grows into a problem around the end of June or first part of July. By August the affected areas are choked with the plant. Interesting link... they say that the first documented evidence of milfoil in the USA was in 1942 and that Wyoming is the only state in the lower-48 without documented infestations. Nasty little weed. Apparently they've used triploid grass carp to get rid of it in many areas. I wonder why it hasn't been used here. We have plenty of carp in this lake, however. They're big enough so that when you bump into them (they like to loll about just under the surface) they can practically capsize an unwary kayaker.
