Northern Water forecast: Above-average runoff

Northern Water issued its second 2011 streamflow forecast on March 7. It anticipates above-average seasonal runoff throughout our district collection and service areas. This is in stark contrast to the dry conditions on the eastern plains.

We compute forecasts for eight basins, all of which either directly supply the C-BT and/or Windy Gap projects or provide native water supplies for Northern Water constituents. Updated forecasts will be published in April and May.

We began developing our streamflow forecasting program in 1999. At first, our forecasting tools were used to provide estimates of supply and demand to the Board as they set the quota allocation in April each year. Now, using customized technologies and tools we developed in-house, we also compute short-term streamflow forecasts to support operational decision-making for our West Slope Collection System.
