Economical way to waterproof a door

We have a walk out basement door that sits at the bottom of a 3-steps down. Right below the door is an external sump pump. Every 5-6 years the lake we live on floods. Is there an economical way to seal the door to prevent water from coming in. I don't care if it means we can't go out the door, we never use it anyway.

I've seen flood barriers online for about $1000 that screw in. But wondering if there are are ideas on how to do it affordably? Like get a piece of aluminum and screw it into the frame then silicone seal it? It would have to stand a winter outside, too.

If not used, remove and block it.

If you never use it you could brick or built a concrete damn around it the max height that water has ever risen. If you build it several feet away you may still have access to the door if need be.

If the door is the only egress you probably shouldn't remove or seal it permanently. Have you tried sandbags? They are a very effective way of blocking water.

My cellar door has a drain just inside the door. Any water that enters there is emptied into my sump.

Thanks for the advice!

One of the challenges is the drainage pipe from around the house goes to the sump pump then there is a second drainage pipe that goes directly into the lake. When the lake water rises water flows up the pipe the goes into the lake and goes directly to our basement door - which sits at the bottom of a 3-step stairwell.
