Against a single opponent on the river what pot odds do you need to correctly call a bet from him?

If you were first to act, maybe you should have bet. (Do a search for "Clarkmeister Theorem" or see
this thread for example.) If you checked, you may have induced a bluff, so it depends on how your opponent plays. If he [edit] ALWAYS [/edit] bets, then LetYouDown is right and you need pot odds of > 1.75:1.

This is opponent based to a large extent, but 99 times out of 100, I'm folding in that spot to any reasonable bet.

However, I'm not so sure about this. Against a player who may bluff or bet a hand I can beat, I'm calling most of the time. To get a number requires solving an EV equation:
P(my hand is best)*Potsize+(1-P(my hand is best))*(-amt of bet I must call)=0
So I have to estimate P(my hand is best) in order to solve for Potsize. If I think my opponent will bet 20% of the time without a diamond and MHIG that same percentage, P(my hand is best)=.2 and I must call 1 BB, then Potsize= 4 BB. To fold very often in a bigger pot, you have to be VERY sure of your opponent, and I don't think you can be that sure of most poker player's tendencies.
