How do you say when a source contains water, but it no longer has its water supplies? So if I pump out the remaining water it will be dry, but it is not dry now.
The same can happen for example by a mine, we can see that this one will be the last lode, and after that we have to close the mine, since we will be out of minerals.
Another example is money, we lost our job and we have some spare money which we know will run out soon. So we are out of money source, but not yet out of money.
Is there any special word, phrase to describe these conditions?
(I currently use dry and exhausted by the source, so I am looking for a better word than exhausted by that example, if that is possible.)
