I spent some time in the pool last night and came up with a bunch of exercises that even non-swimmers can do in the pool as a form of off-ice training.
First, swimming laps is outstanding for building strength and flexibility. I did about 10 laps in various strokes to warm up, including side stroke, which I've always liked for the hip workout. (Since I forgot to bring a cap/goggles, it's also good for keeping your face above water, lol.)
Second, walking/jogging laps. You can use a kickboard, water dumbbell or even a pool noodle to provide resistance. Don't just work out in a forward direction - walk/jog backwards as well. It's good for core and lower body.
Third, grapevines:

I also did some pseudo-skating jumps in the water. Our pool wasn't deep enough to use the steps to jump off, so I just did them from a standstill or a side-tap entry. It was okay; I could pull in and jump up out of the water and I really had to fight for the checked landing position. I'll try a more shallow/deeper area next time.
