Site available showing current elevation of lakes?

[Anglinarcher]

I can't find one, so I thought I would ask the group.  Is there a source to find out the current water elevation of bodies of water.  

I have a toy I have not used and would like to start mapping some of the lakes in Utah (most are not mapped on the fish finders).  If I record it with the water level 20' low, I need to correct with a depth off-set.
