Precipitation Report for the week of 7/3/19

The Lake Almanor basin finished the July-June “Water Year” with plentiful totals of both snowfall and rain.

In the snowfall category, most of it arrived in January and February instead of being spread out over a longer span.  The grand total snowfall for the season was 200.5 inches (16.7 feet) on the west shore, or 157 percent of the long-term average. Deep snowpack and tall roadside berms caused many a grumpy morning during winter!

Total precipitation mirrored our snowfall trends, although we received rain over a much longer period. Overall, the Prattville monitoring site registered 47.96 inches of total precipitation, just shy of an even 4 feet. That accumulation amounts to 151 percent of the long-term annual average.

The extended flow of the Chester Flood Control Channel and the elevated Lake Almanor level bares testament to the amount of water received both locally and in the upper elevations that feed into the lake. Many of the outlying areas were snow covered until late in the spring.


Putting things in perspective, the Basin has continued to enjoy near- or above-average precipitation during most recent seasons.

Starting with the 2008-2009 water year, we have had only two seasons when the total precipitation was 80 percent or less of average during that 11-year period.

On the other side of the scale, we have experienced four seasons with total precipitation at 140 percent or above during the same period.

The healthy conditions of our trees and yards are a direct result.
