Below are some previous similar questions with answers which should help. Leak can be from a leaking fitting on top or at the elements ( if electric) or at the control valve penetration or a leak at the relief valve (at fitting or the valve itself leaking), which can normally be fixed. Or can be a leaking tank, which cannot be fixed - has to be replaced.

Plumbing is of course the Search the List category to find well-rated and reviewed vendors to have one come out and diagnose the cause if you can't.

On the leaking after the valve is shut off (presuming you mean a shutoff just above the heater) - that should shut off the incoming cold water flow, but the tank will continue leaking till the household hot water pipes higher than the tank have drained down at least, and if the leak is below the top of the tank until the tank has drained down to there too - so potentially a few to maybe 5 gallons or so in the pipes, and typically 30-60 gallons from the tank itself. Because you do not know when this will change from a drip or slow leak to a flood, I recommend closing that valve, turning gas control valve to OFF, then draining the tank if the leak would cause damage if it went to a full flood - using a garden hose from drain valve at bottom of tank to a floor drain or outdoors if the heater does not have a drain pan leading to a drain. Note water will initially be very hot unless you let it cool for a few hours, so be cautious about spills, and also some plastic hoses melt at those temps.

Note if the water flow does not drop to nothing in 5 minutes or so (you may need to open hot faucets to let the water drain out of the pipes), it may mean uyour inflow valve is not totally shutting off, so you may need to leave hose connected and lesding to a drain or outdoors to stop the heater leak.
