According to Boulder OEM:
Barker Reservoir is among the lakes and reservoirs throughout the county that are at or near capacity, with water pouring over the spillway as we receive more rainfall. This is a normal function for the reservoirs under these conditions. Specifically, you may see spillover from these area reservoirs:
- Union Reservoir in Longmont
- Button Rock Reservoir west of Lyons
- Barker Reservoir in Nederland
- Wonderland Lake in Boulder
The dams and spillways are functioning as designed. Seeing water in the spillway is normal during times of heavy rainfall or runoff. As always, stay away from moving water and do not try to enter any flooding areas.
DO NOT GO NEAR BARKER DAM OR THE RESERVOIR AT THIS TIME.
