Elks (which are usually known as "moose" by United Statesians or Canadians) are the biggest deer, and can jump very well, I'd say they can clear higher fences than wolves. They can also both swim (up to 20 km) and wade, and even dive (submerge) with no problem, often eating vegetation from the lake or river bottom (they can hold breath for ~50 seconds).
They actually are capable of submerging to escape wolves, though against a single human they would prefer to just run, running faster than any hunter.
Reindeer don't frequent my country, but the photos of reindeer fences in Finland I saw suggest that 2m should be enough. As all deer then cam jump forward (though not as far as elks it seems), and of course can swim.
If I was implementing jumping, I would correlate it with size somehow, for example calf couldn't jump as far as adults. But I know that even youngest reindeer calves can outrun a human.
