The cofferdamn can't be used as a measuring device as 1) you really cant see into it. 2) its one liquid in it displacing another.
1) You can't really see much inside a 10,000 bbl barge, but you don't have to take a swim in its contents to measure how much is in it.
2) Yeah, that's actually WHY you can measure it. If it was one liquid mixing evenly with another, measurement would be much less practical. But since the oil tends to stay separate from the water, floating on the top, all you've got to do is measure the time from the point when the thing got clogged to the time when oil started flowing out around its base, then take the total known volume of the dam and divide it by that amount of time - voila, you have the leak rate.
