When is a flow rate not just a flow rate?
The source of water also matters.
After a regular routine of spring and summer discharges from the Lake (to date the S-77 has released a little over a half million acre feet into the river) – for the last two weeks those source flows had quieted down to a trickle.
That’s why I was surprised to see a sudden rise in the downstream S-79. It ended Monday at almost 4,000 cubic feet per second (cfs) and averaged 2,000 cfs for the week?
What’s going on?
Notice how hardly any of last year’s estuarine flows (via the S-79) came from the Lake (S-77) in comparison. That may partly be a result of last year’s tranquil hurricane season, thus creating less of a need to free up storage capacity.
Those rains are unpredictable you know (i.e., Fay in 2008)!
