Ontario, clear water lake that has a good amount of milfoil but this grass is around. It’s typically to the top of the water in as high as ten feet or more. It’s sparse, bass do not seem to relate to it like the molfoil 

 

 

My belief is "Clasping leaf pond weed"

 

@Ski is correct. -- that is clasping leaf pondweed -- it is the primary native deep-growing vegetation in northern natural lakes.  This is usually what people (Mark Zona, and In-Fisherman for instance) mean when they say "cabbage."

 

Bass very much do relate to it, but because it is so tall, and often grows in large fields, they can be at any depth and any location.  Lakes vary widely in how dense it is, and how much it is mixed with other stuff like milfoil, coontail, etc. 

 

Most of the natural lakes in our area (W. Michigan)  have at least some of it, but it can get choked out by stuff like invasive Eurasian Milfoil and Curly-leaf pondweed.

Coontail or milfoil?

@Bandersnatch I would guess coontail. Milfoil usually has its leaves more spaced out on the stem. I’m not 100% though. 

It's hard to tell -- milfoil tends to collapse when out of water and it kind of looks like it's doing that, even with all the algae, while coontail usually holds its shape better. Coontail also tends to branch more and gives sort of a "christmas tree" look in the water. 

This is a good reference from FL DEP.

Here is a decent one, but from Rutgers so more northern specific

 

 

And here's a guide from State of Michigan, drawings rather than photos, but good summary and descriptions of the main plants around here:

Took me a min to find it again, but here’s one that covers the TVA river/lake system.

I'm casting my vote for Coontail but it's hard to get a sense of scale with the photo.
