Oh boy - that fish does look not good from the photo. It's bloated for sure - any idea how long it was dead? Did you notice anything unusual about the fish before it died? The gills on one side look bad, but if the fish was dead for a while a lot can happen after death.
A few details about the pond - how big, how many fish, what kind, how old, type of filtration, etc. Do you test your water?

It was alive yesterday just noticed it this morning! No it seemed ok, but I am not sure to be honest, the pond is about 7 ft x 5ft and 3.5 deep ish! We had about 40 fish in there at one stage but we knew that was too many so now have about 20, it has an oase filter system installed the oase 4000 uv , never tested the water, this is the first time this has happened! I have put other threads on here as we have trouble getting the water to clear but I think that is due to sun being dir3ctly on it and the rainwater run off gets in there but we are going to be rectifying that,
Just under 1000 gallons - 20 is definitely better than 40! All goldfish?
I am no fish expert, but I can tell you two things:
1. sometimes fish just die
2. when a fish gets bloated that's usually dropsy which is fluid build up. But like I said - fish will also bloat after they die, so if you didn't notice it was bloated before (and it's not so bloated now that it's obvious) it may not mean anything at all.
Do you see any sign of injury on the fish?

The " green" on the fish makes me think of https://www.koisale.com/saprolegnia-fungus.html
Here is some information on it. Very sorry for the loss of your fish.

Does the dead fish have a notch in the nose? Hard to tell from the pictures.
The bloating could mean possible kidney failure or maybe a tumor. Might also be egg bound. Too many possibilities to make a judgement. You could always open up the fish and see what you find.
I would agree with Tula about the green. Usually it grows on an open wound on a fish.
Might be a good time to get some liquid water tests and check the water parameters.

You mentioned rainwater runoff- any chemicals on the surrounding ground can get washed into the pond. That would be the first thing I would fix.
