From the Summit County Citizens Voice:
Denver Water officials said the cool and rainy weather cut demand for water recently, so Dillon Reservoir is once again full to the brim, with some water spilling through the glory hole. Inflows to the reservoir were at about 350 cubic feet per second as of Tuesday morning, but that volume is expected to drop again rapidly when the rains stop.
Rains only provide a temporary boost to stream flows, and with the early melt-out of the high country snowpack, there’s not much backup moisture to sustain the flows. Blue River Basin water commissioner Scott Hummer said the entire Upper Colorado River Basin remains on the National Drought Monitor under the “abnormally dry” category, and before the monsoon kicked in, Colorado River flows had dropped to near record low levels.
