Trying to identify a submergent weed that looks like a cross of Eurasion milfoil and Coontail. It grows in mats. When pulled it stinks like garlic (good fertilizer when dry). When it blooms in late,late spring or early summer, no flowers seen with naked eye, but it creates a foamy scum (maybe this is how it spreads). you can pull out with a garden rake but it is a heavy mat. If someone can ID this - would areation control the spread. I did notice in some years when windy'er (perhaps do to El Nino) it spread less after pulled (maybe just coincidence).
