The following conditions influenced this month's forecasts:

Precipitation:
Seasonal October through May precipitation was 82 percent of average in the upper Bear Basin. May precipitation was 66 percent of average.

Streamflow:
The Bear River at Utah/Wyoming Stateline last month was 76 percent of average. The regulated inflow to Bear River at Stewart Dam was 6 percent of average. The Logan River above State Dam was estimated at 73 percent of average streamflow.

Snowpack:
As of June 1st the Bear Basin snowpack has melted out in one of the earliest melts we've seen. As of water year 2012 the CBRFC has re-calculated all snow stations to reflect the new 30 year average from 1981-2010.

Climate Forecasts:
Climate forecasts were not a factored into the northern Utah forecasts because there is not a strong correlation between La Nina conditions and winter precipitation.

Forecast Summary:
Overall the winter of 2012 has been drier and warmer than average. Seasonal precipitation throughout the Bear Basin as of June 1 was 82 percent of average. Indexed snow water equivalents on June 1st were zero, indicating that in terms of runoff, the snow is now gone. Streamflow forecast have been reduced significantly since March, as warm temperature and below average precipitation numbers have drastically reduced streamflow volume forecast. The June through July forecasts are now ranked in the top 5 lowest years on record. April through July seasonal volume forecast range from 21 to 56 percent of average with a median volume of 51 percent of average.

The following conditions influenced this month's forecasts:

Precipitation:
Seasonal October through May precipitation is 72 percent of average. May precipitation was 52 percent of average.

Streamflow:
The Weber at Oakley gage was estimated to be 67 percent of average. The inflow to Rockport Reservoir was 47 percent of average.

Snowpack:
As of June 1st the snowpack is all but gone except on the highest peaks and runoff has finished. The current snow water equivalent index is zero percent of average. As of water year 2012 the CBRFC has re-calculated all snow stations to reflect the new 30 year average from 1981-2010.

Forecast Summary:
Overall the winter of 2012 has been drier and warmer than average and resulted in very low streamflows. Seasonal precipitation throughout the Weber River Basin as of June 1 was 72 percent of average. Indexed snow water equivalents on June 1st indicated that in terms of runoff, the snow is now gone. Streamflow forecast have been reduced significantly since March, as warm temperature and below average precipitation numbers have drastically reduced streamflow volume forecast. The June through July Weber Basin forecasts ranked in the top 5 lowest historical years on record. April through July seasonal volume forecasts range between 28 and 52 percent of average with a median forecast volume of 37 percent of average. Here's hoping for a wet summer and a much better water year 2013.

The following conditions influenced this month's forecasts:

Precipitation:
Seasonal October through May precipitation was near 74 percent of average. May precipitation was 46 percent of average.

Streamflow:
May streamflow for City Creek near Salt Lake City was 47 percent of average. Big Cottonwood Creek nr Salt Lake City was 58 percent of average.

Snowpack:
As of June 1st the snowpack are all but gone with only residual snowfields at elevations above 10000 feet. The has now effectively ended in what will be recored in history as one of the earliest melts ever. As of water year 2012 the CBRFC has re-calculated all snow stations to reflect the new 30 year average from 1981-2010.

Differences between the full period forecasts and the residual forecasts may not exactly equal the actual observed volumes due to rounding conventions (see Definitions section).
