[quote=maura;498277]You might find it really useful to reinforce going forward off your leg promptly away from the water. Includea voice command such as "walk on" but insist that you get an immediate response. Use a stick if you need to.
Treat the issue with the water as a disobedience to your leg aids, rather than about the water, per se.
I agree with this. Once your horse comes off your legs everytime you'll be able to ride her in so many different places. I perfer spurs over a stick, reason being, with the stick your don't have both hands on the reins or infront of you. If you are urgeing your horse forward with a stick and she goes to vear off you'll have a harder time keeping her straight with only one hand. Also, using spurs your can escolate pressure. If you can ride your horse without haveing to spank her everywhere other than water crossing then she knows how to come off your legs, so why use something that's not attached to your legs. I'm not saying you should jump on and start jabbing your horse with some spurs, what I'm saying is you start with a bump from your leg, then another, then roll(not jab) your spur up the side, then add some more pressure while rolling then bump her with the spur. I garantee you that the spurs will be more effective and easier to use then a stick or flag.
If she truely is affraid of water, try some sending excersizes. Lung her around the water and every few circles around take a step or two towards the water. You could stand 5 feet from the water and send her between you and the water, keep doing it getting closer and closer, only going closer when she's really good at it.
