Dust Wars

Somewhere, in a galaxy far, far away, there might be people who thrive in the midst of dust. That's not us. Dust storms here on earth can be dangerously unhealthy. Dust storms don’t just happen in the middle of Tattoine or in the Oklahoma Dust Bowl. In our state, dust is more of an issue in Eastern Washington, but can be a problem anywhere given the right (or wrong) conditions.

Sand People, Star Wars: A New Hope.

While agricultural lands and activities have been the primary source for dust storms in Washington, we’re seeing fewer per year, thanks to better farming practices.

Dust storms have become less common in Washington since the mid-1990s when farmers started using more soil erosion prevention techniques. Those farming techniques have made a difference: In the early ’90s, Kennewick had as many as seven dust storms in just one year! Compare that to the past six years, when the area only had seven dust storms in total. That means cleaner air and healthier people.

Judge by size, do you?

Strong winds and dry conditions cause large amounts of soil to be blown into the air. When that happens, it’s hard to see, making driving dangerous. Plus, all of those large and small particles sting your eyes and sandblast your body. The tiny particles — known as PM10 and PM2.5 — can get deep in your lungs, causing irritation and worsening existing asthma, allergies, and heart disease.

Keep dirt on the ground

Ecology and our clean air partners monitor the air for dust and other pollutants. In areas where windblown dust is a problem, we work with U.S. Department of Agriculture program partners to minimize soil erosion. We’re piloting a grant project in Benton, Franklin, and Klickitat counties where dust blown from farm land causes Kennewick’s air quality to be unhealthy.

The focus will be on farms in the Conservation Reserve Program — a land conservation program that pays farmers to take land out of production and maintain plants that anchor soil. As these conservation contracts expire this fall and land goes back into use for farming, the grants will support farmers’ use of farming methods that keep dirt on the ground and out of the air.

Be prepared

When there's a dust storm, pull over if you're driving and stay in your car. Don’t exercise outside. Cover your nose and mouth. Get inside if you can and close windows, doors, and vents. Sign up for Dust Storm Alerts from the National Weather Service to find out when high winds are forecast.

Raise a lightsaber

Dust may not sound as dangerous as other types of air pollution, but it can be just as harmful. The best way to prevent dust is to continue encouraging farmers’ efforts to find new ways and use tested methods to prevent soil erosion. Ecology and our clean air partners have made a lot of progress over the past few decades. We’re committed to protecting your health.

New Management Program for Lewis County shorelines need public input

County residents have until March 16 to weigh in

With more than 1,100 miles of river shoreline, Lewis County's new Management Program will affect
residents throughout the county. 

If you appreciate shoreline ecology, you’ll like the waters of Lewis County. The county boasts more than 1,100 miles of shoreline, including the Nisqually, Chehalis, Deschutes and Cowlitz rivers, numerous tributaries and 34 lakes.

Restoration of the Upper Chehalis River is a priority under the new Lewis
County Shoreline Management Program.

That’s a lot of water front property.

Lewis County has proposed changes to how it manages the edges of those waterbodies and the Department of Ecology is asking the public to weigh in on those plans. Ecology will compare the county’s proposed program to the requirements of the Shoreline Management Act and the Shoreline Master Program Guidelines. Based on the comparison and the comments the plan receives, Ecology will decide whether to approve the program or ask for changes.

Lewis County’s first Shoreline Master Program was adopted in 1974 and last amended in 1998. The comprehensive update now under consideration prioritizes water-oriented uses and development, protects sensitive areas and includes a restoration plan for degraded and damaged shoreline.

The restoration plan is a 98-page document that identifies priority projects within 16 management areas. An example is Lewis County’s five Upper Chehalis Management Areas, which include hundreds of river miles along the Coast Range, Willapa Hills, Puget Lowlands, Western Foothills and Cascade Lowlands, along hundreds of river miles. Restoration priorities include improved fish passage, restoration of riparian vegetation, and reconnecting the main stem of the Chehalis River and its tributaries with their floodplains..

The public has until 5 p.m. March 16 to comment on Lewis County’s program.

Lewis County’s proposed Shoreline Master Program can be viewed online. Paper copies can be viewed at Ecology’s Southwest Regional Office, 300 Desmond Dr., Lacey, WA 98577, or at the Lewis County Community Development office, 2025 NE Kresky Ave., Chehalis, WA, 98532.

Comments should be addressed to Ecology’s Kim Van Zwalenburg. Here’s how to submit them:

Watching the water supply

This blog post is part of an ongoing series about water supply conditions. Please click here to read the previous post. If you want to learn more, visit our Washington water supply information page.

Have we seen the last of summer’s high temperatures? The arrival of more moderate weather may feel like fall for many of us across the state. As we begin to transition into the next season, let’s check in on our statewide water supply conditions.

Status of our supplies

Weather impacts | Cooler and wetter weather is on the way. Over the next 10 days, Washington will receive much-needed rain. While the amount may be modest, it will help our rivers and streams rebuild to higher levels while lowering water temperatures.

The Walla Walla River in southeast Washington ran low in

August. 

Rivers and streams | This is the time of year when rivers and streams are at their lowest levels. The snowpack is long gone and rain has been infrequent, so rivers and streams are relying on groundwater. Currently, about 48 percent of our streams and rivers are at below-average levels compared to historical flows. Most of these are in the western half the state, though southeast Washington also has a number of low rivers. These dry areas have gone without their usual share of precipitation since early spring.

Last year, we experienced a record-setting drought that resulted in 70 to 80 percent of our rivers being below-average for most of the summer. But in mid- and late August, the weather turned cooler and thunderstorms rolled across the state, dropping the percent of rivers flowing at below-average conditions to 40 percent. Compared to last summer at the end of August, our rivers are actually faring worse because we haven’t had those big storms yet.

Agriculture | Most of Washington’s agricultural areas experienced a dry and hot August. Crops are doing well for the most part, but farm ponds and reservoirs are getting low. The large federal reservoirs used for irrigation in the Yakima River Basin are at about normal levels, which is good for farms and fish. Farmers in the Yakima region holding junior water rights are receiving 94 percent of a full water supply. Senior users have 100 percent.

Fish | Low flow levels in rivers and streams can be tough for fish, but cooler overnight temperatures are helping. In the Puget Sound area, streams are averaging 1 to 3 degrees Celsius cooler than in 2015. To the north, the South Fork Nooksack River is about the same temperature as last year. The Chehalis River and nearby southwest Washington streams are running very low compared to normal. Good news can be found in the Upper Yakima and Naches river basins, where bull trout have started moving out of Bumping Lake and into streams to spawn. That’s encouraging after what happened last summer, when low lake levels prevented the fish from moving into Deep Creek, an important bull trout stronghold.

The Washington Department of Fish and Wildlife continues to watch for recreational rock dams that might impede upstream adult salmon passage.

Drinking water | Drinking water supplies are doing well. Seattle, Everett and Tacoma report normal or above-average water supplies.

How you can help

We all have a role to play in conserving water. Here are two ways you can make a difference:

• When washing your hands, turn off the water while you lather up.
• Don’t use your toilet as a wastebasket. Even better, use a leak-free, high-efficiency toilet. Toilets are by far the main source of water use in our homes – they account for nearly 30 percent of residential indoor water consumption.
