Streamflow Forecasts

Northern Water’s Snowpack and Streamflow Comparisons reports show snow-water content comparisons and streamflow forecasts for the watersheds in the Colorado-Big Thompson Project. Northern Water publishes the reports on this page from the beginning of February through the beginning of May. Go to the SnoWatch Snowpack Data page for snowpack data from remote Snowpack Telemetry (SNOTEL) platforms in eight watersheds, covering an area from west of Loveland, CO to east of Kremmling, CO.

February 2020 Streamflow Forecast*
February 1 snowpack is at or above average in most basins except for Willow Creek. Streamflow forecasts are generally a bit lower than we would normally expect with these snowpack conditions due to the impacts of the hot and dry conditions in late summer 2019 on soil moisture. The forecast for most basins is around 90-100% of average, though Willow Creek is lower due to the lower snowpack. Learn more>>



* A small note that our Upper Colorado River and South Platte
Tributaries snow water equivalent values are weighted differently from NRCS values, effecting the percent of average calculations.
