Do please correct me if I'm wrong but the base yield of an unworked riverside plains at machinery is 1 food and 2 hammers. You chop the forest and do nothing it becomes 1 food, one hammer, and 1 commerce. A watermill at machinery gives you +1 hammer to a riverside tile, that brings you back to 1 food, 2 hammers, and you get that extra commerce.
And if the lumbermill is on a flat side of the river (not a corner) it will also yield the +1 commerce. Watermill gets no railroad bonus, while the lumbermill does. An IW city with most of the BFC (apart from food tiles) packed with lumbermills and railroads yields an enormous number of hammers, and because the trees are still there you have no worries about the unhealthy hit from IW and coal, power, etc.
This is a mid-late game condition though, and to achieve it you have to sacrifice some potential early hammers from chops within that particular BFC.
I was saying that in short games on small maps you're better off with a watermill because you get a slightly better tile long before you can work a lumbermill for just the cost of some health. My math does of course presume that you're working a riverside tile though.
The best use of that riverside tile if you chop would be a farm or a cottage, depending on what else the city will be working (mines for farms, cottages for other cottages). You can watermill it later, but it's best to improve that tile to something else prior to Machinery.
Also, it goes without saying, that not all chops that you chop have to be within your city's BFC or even within your borders. One of my favorite missions for workers not doing desperately-needed land improvements is "ninja chopping", off in foreign lands right outside their culture chopping down the forests of city sites they might otherwise gain yields from themselves after they settle there. Or up in the tundra, etc. (with units as they train up fighting barbs).
