Does El Salvador have any cs?

I tried "El Salvador, waterways." Looks like there is just one navigable river, and no cs that can be used by boats. See 1st site below. Several other sites also said there is just that river that can be used by small boats. Then, I looked up "irrigation cs, El Salvador." The few sites I found said there are no actual functioning irrigation cs, just a few that are basically just ditches. See 2nd site. Oh, and Google is worthless, so limited. I always do far better using Yahoo Search.
