That depends on the type of skimmer in ground or above ground and from what material it is made, The water is leaking between gaskets
i think its up
Attempting to obtain step by step diagrams connecting an above ground pool to a sand filter.
If you can get the right skimmer you should not have too much of a problem However if you cant get a replacement you may be able to get out of it by getting a floating pool skimmer with inline leaf basket.
6 inches below skimmer.
The water will spill out through the skimmer, unless the skimmer it is blocked. Otherwise, it will spill over the top. It should not hurt the pool.
Drain the pool until the water level reaches two inches below the skimmer faceplate , remove the face plate using a screwdriver , remove the faceplate and skimmer , then replace the gasket and attach the skimmer and then the faceplate
Cut out the shell to fit, or if smaller fill with concrete mix
I may be wrong but I doubt there is a scum gutter on above ground pools. There may be what is called a skimmer and that is sort of a hollow box like object at one side of the pool - usually located closer to the pool equipment side of the pool. When the pool pump is running you will be able to see water entering the box or skimmer. The purpose of the skimmer is to catch bugs, leaves, etc and to get the water back to the pump. It is part of the circulation system.
Generally, the skimmer area of the pool can be sleeved with PVC if there is a leak
Add thru the skimmer box
turn the pool pump off,take off the cover of the pool skimmer box, The pool water level must be above the area where the skimmer box meets the pool wall. If it is not, add water to the pool until it is at least 1 inch above this seam.
You can cut a new piece of metal to size, with the appropriately-sized hole for the skimmer, and replace the rusted metal with the new piece.
The pool skimmer is the part of the system that the water overflows into for the pump to pump it thru the filter and other accessories. There is usually a screen or mesh basket to catch large debris before it enters the pump. On above ground pools it will be found hanging on the outside of the pool near the top. In-ground pools can have the skimmer placed anywhere along the perimeter with a basket or screen accessible for cleaning.
Just enough so that the skimmer is above the water and the pipes to the filter and filter can be drained.
With a filter, vacuum, skimmer net, brush and water sanitizer like chlorine to get the exact details have a talk with your local pool shop.
If you have the regular set up that includes a skimmer, pump and filter then you don't have to waste any water. Get an lid-to-hose adapter, that fits over the skimmer basket at your pool supply store. Fill the hose with water and attach it to the lid. Place the lid inside the skimmer over the skimmer basket, then vacuum to your hearts content. Pool Masters
If this is an above ground pool you could just pull the old skimmer out cut the rusted section of metal out hit it with some rust converter, replace the section where there is no metal with a new metal forget about the old skimmer setup and replace it with a "floating pool skimmer" they do a better job any way.

Replacing a damaged pool skimmer can be a difficult and expensive undertaking. a way to avoid the work involved would be to install a floating pool skimmer this would mean you have nothing to worry about but a hose connection and possibly an inline leaf canister. Check out the Australian Dragonfly pulse surface cleaner also available in the USA.
GET OUT! just teasing but you should scoop it out before it gets into the skimmer or vacuum hose and shock heavily with chlorine.
I have cleaned and added my winter chemicals and am in the process of draining below the skimmer but my water looks a little cloudy is that normal ?
