Drought Misinformation

There have been several stories in the Seattle Times and some local media that have hyped and exaggerated the "drought" over Washington State.

For example, a few days ago, the Seattle Times had a big spread talking about drought for the Yakima River basin:

The lack of rain and snow forced farmers to tear out their apple orchards by the acre. Wine grapes are withering on the vine. Miles-long irrigation canals leak and crumble.

This basin is the face of Washington’s drought. This might be the driest year in recent memory, fresh on the heels of severe droughts last year and the year before..

They had a picture of Lake Keechelus that showed it being completely dry.


Very deceptive.  I went up there on Sunday and this is what I saw:


They took a picture of one of the lake flanks, which is always dry during this season---even during a normal year.  

This is not honest journalism.

The truth is that the Yakima Reservoir system is rapidly filling, and Yakima River levels are normal.  

Still believe the Seattle Times?  Let's look at the actual numbers.

Below is a plot of storage for the entire Yakima system over time, showing average values (red), last year (green), and this year (blue).

This year, we are WAY higher than last year and rapidly refilling.  

In fact, the current storage now is about the same as last year, ONE FEBRUARY 1.


What about the water flow in the critical Yakima River?   (see below)

The flow is now above normal, and the prediction is for it to stay that way.


The Seattle Times is making all kinds of serious drought claims, with a lot of hints about global warming being the cause.

But is precipitation really declining over time on the eastern slopes of the Cascades, the watershed area for the Yakima Basin?

Let's check, using the official NOAA climate division data.  

Below is a plot of October through August precipitation totals on the eastern slopes of the Cascades.


Both the last two years were below normal.  No doubt about that.  But other years were drier...some much drier.  

Importantly, there is no long-term trend toward drier conditions, which is a sign of climate change. 

 Climate change is not the origin of the last two dry years....it is natural variability.


This year is clearly going to be substantially moister than the last two years.

There is a critical issue that the Seattle Times and certain activists never consider:  

Is a drier-than-normal year really a big deal?

 For example, if the Yakima Valley region receives more precipitation than it really needs on average, is being down modestly a problem of any significance?

It turns out that the "drought" had very little impact on Yakima Valley agriculture:
  • The 2025 Yakima Valley apple crop was large and high-quality, with a record-tying amounts.
  • The 2025 Yakima Valley cherry crop was excellent, with a good-sized and high-quality harvest resulting from favorable weather conditions. The cherry season was particularly long this year.
  • The 2025 Yakima Valley grape crop is expected to be a "standout vintage" for quality.
Bottom line:  the agricultural impacts of the "drought" were very minor for the eastern slopes of the Cascades.

In a future blog, I will take on the Seattle Times' claims about drought on the western side of the Cascades.    

But I can't help myself.  Here are the latest reservoir levels for Seattle

Precipitation has been a bit above normal over watershed


and reservoir levels are rising rapidly and are almost at normal levels

  1. The big drought is Seattle Times Climate Lab fundraising; without a donors deluge and they will dry-up.

  2. Thanks, Cliff. Under a warmer climate, do you know if we have enough reservoir capacity? If the snow at lower elevations warms earlier in the spring, will we have enough volume to store that extra capacity to last the growing season?

  3. Hi Cliff, do you expect the Yakima basin to need more reservoir storage under a warmer climate?

    1. Yes, more reservoir capacity makes sense, particularly as more water falls as rain rather than snow.

Please make sure your comments are civil. Name calling and personal attacks are not appropriate.
