From USBR:
Even with the rain this week and the slight warm up, we’re still not getting much inflow to Twin Lake. I suspect whatever is coming down is being soaked up by the dry soils. We’re going to decrease the Twin release from 85 to 50 cfs at 09:30 this morning, 6 May. The release is all native.
