From email from Reclamation (Kara Lamb):
You might have already heard, but today [May 3] we turned off the pump to Carter Lake. Carter is now about 94.5% full. With the pump to Carter off, about 508 cfs is now flowing north to Horsetooth Reservoir. Horsetooth is about 75% full and will continue to rise through May.
