Snowpack percentages at higher elevations continue to increase with the cool, showery weather, while at lower elevations the snowpack continues to melt. Seasonal water supply forecasts edged slightly lower from those issued at mid-April, but are generally a little higher than those issued at the 1st of April.
Some forecasts continue to hover just above the minimum flows of record.
Spring weather will likely dictate whether these extreme low flow records are broken or withstand an unusually dry year. The previous low flow of record for this period is 44.0 maf set in 1944. They are created using a set of index stations. The plots compare current accumulated readings with other significant years, the average conditions, and maximum and minimun values.
