What Does All This Rain Mean for California’s Drought?

As you’re effectively conscious, California has had an especially moist winter, replete with extreme flooding, snowed-in mountain communities and a large snowpack accumulating within the Sierra Nevada.

So what does that imply for the state’s drought?

In January, after back-to-back atmospheric river storms, it was nonetheless largely unknown whether or not the downpours might reverse our drought, which started in 2020 and has stretched by means of the three driest years on file within the state.

On the time, many specialists mentioned that it might very seemingly take a number of moist months, and even a number of moist seasons, to finish the drought — and there was no telling whether or not the moist climate early within the season could be adopted by a dry spell, which is strictly what occurred final yr.

However this winter has continued to deliver torrents of rain and snow by means of March, which has modified the drought outlook.

I labored with my colleagues Mira Rojanasakul and Nadja Popovich on a set of maps and charts that illustrates simply how massive of an impact these very moist months have had on the Golden State’s longer-term drought situations.

While you take a look at how a lot precipitation California acquired over the previous three years, excluding this winter, you’ll discover that just about all the state skilled ranges far under what’s regular, with regular outlined as the typical precipitation acquired between 1991 and 2020.

However whenever you embody this winter’s rain and snow, the image shifts: The precipitation that California acquired between December and mid-March has offset a lot of the shortfall that collected over the previous three years.

The rains have helped replenish reservoirs, a lot of which have shortly returned to their historic averages, or surpassed them. Snow has constructed up snowpack ranges statewide to the best they’ve been in a long time — greater than 3 times what they had been on the identical time in every of the final three years.

That is undoubtedly a silver lining to our excessive climate of late. However specialists are nonetheless hesitant to say definitively that California’s drought is over, for various causes.

First, regardless that storms could briefly ease the dry situations, drought is prone to return comparatively quickly. California has lengthy cycled by means of spells of deluge and drought, partly due to pure local weather variability. However analysis suggests {that a} hotter local weather has supercharged the “whiplash” between these extremes.

Second, even an especially moist winter isn’t a magic bullet for the long-term water considerations within the state, which have been exacerbated by years of maximum aridity, rising temperatures and unsustainable water use.

California’s groundwater aquifers have big potential for storing water; they will maintain eight to 12 instances as a lot as all the state’s main reservoirs mixed. However, they’ve been badly depleted by a long time of heavy pumping, particularly within the agriculture-heavy Central Valley. Knowledge means that groundwater provides within the area decline precipitously throughout dry durations, recovering solely modestly throughout moist ones.

On the subject of replenishing these aquifers, the state has had bother capturing water from downpours and redirecting it to fields and sandy basins the place it could possibly seep underground, specialists say. Which means we nonetheless have a protracted technique to go in restoring our groundwater provides.

Heavy influxes of rain and snow through the winter may have damaging repercussions later within the yr. The state’s record-level snowpack might imply extra flooding within the spring because the snow melts, particularly if a lot of the soil is already saturated with water and may’t take in far more of it.

And, as Alex Corridor, the director of the Heart for Local weather Science on the College of California, Los Angeles, identified to me, disputes over the dwindling Colorado River nonetheless loom. Seven western states, together with California, rely on the river for water, however these states have struggled to scale back their water use even because the river’s circulation has plummeted due to local weather change, drought and inhabitants progress.

Current rains are usually not practically sufficient to alleviate a disaster that has been a long time within the making, Corridor mentioned. “We would wish a number of years of fine and wholesome water inputs to get better.”
