Evaporation?

• tzs 5y ago
  That seems like a reasonable explanation for why they might have less water to discharge than they sucked in, but I don't understand why it would be written into the limits of what they are allowed to suck out and discharge. If they were to take 139 MG one day and only 2 MG were lost to evaporation, so that they had 137 MG left over, I fail to see the logic in saying that they can only put 135 MG of that back into the lake. That's effectively saying that if they take their limit of 139 MG per day, then they are required to net drain the lake by 4 MG per day. I'd have expected the limits to be of the form: You can take up to X per day, you can put back up to what you take, and you must put back enough so that the net taking for that day is less than T.
