Water heater leaking through top

This is at my dad's house. He has alzheimer's and is on a fixed income so I would like to solve this as inexpensively as possible even if it is only a temporary fix.

I saw water coming from underneath the red disk thingy on the hot water outlet, indicated by the red arrow on the left, and I thought some might have been swirling up from the hole with the other arrow on the right, but I'm not sure about that one.

We are in a drought here, and the house is spring-fed into a cold water holding tank, so it's possible some sludge or sand from that tank might have gotten into the heater, but I'm not sure about that either.

Water from the bottom (cold) release on the heater has some sand in it but not too much. Didn't look sludgey though. I didn't drain much. Water from the hot release which is closer to the top looked clear.

The water from the heater is the same temp as always.

I am hesitant to drain it because I don't want to waste water, but maybe that is the thing to do first?

It looks like the tank is leaking from the hot water fitting. If it was just the cold water connection you could repair it. Unfortunately it appears to be coming from the point where the fitting is welded to the tank and there is no repair for that.

*hot fitting
What would cause that to happen, so I can avoid in the future?

How old is that tank?
Leaking from the top I 100% agree time for a new tank.
Water heaters should have had a garden hose connected at least ever 6 months to the bottom drain and ran for about 15 min. to drain out the solids in the bottom of the tank.
Wasting water, I think not.
To late now to try and do the required maintenace.
It also looks like there just 1/2 lines running and out of that heater.
3/4" would have about twice the flow of those 1/2" lines.
