Mix well with fingers as this your last chance to make sure no crab shells are in mixture. Pour crabmeat into Dutch oven, over vegetables. Pour water and lemon juice into bowl swishing around to pick up remaining crabmeat on sides of bowl. Mix well and cook for 15 minutes with lid on over a medium low heat. Add 3/4 cup bread crumbs to crab and vegetable mixture.
