ICL's 2021 groundwater report now available

The Idaho Conservation League’s latest groundwater report details a continuing trend of poor water quality in the Magic Valley. These findings solidify the serious concerns raised by ICL’s previous groundwater reports that the drinking water source for more than 300,000 Idahoans – the Eastern Snake Plain Aquifer (ESPA) – is significantly degraded.

Solutions Together

The Columbia Basin Initiative

For years, ICL has been concerned about the health of the Snake River and the region’s water quality. In 2021, Congressman Mike Simpson put forward a proposal that could reduce pollutants in the Mid and Upper Snake, while restoring endangered fisheries. His “Columbia Basin Initiative” would help restore Idaho salmon and steelhead, and includes investments specifically in Snake River water quality. His concept invests $1.2 billion into Snake River watershed partnerships, waste management research, and methane digester development. This investment would result in cleaner water for our communities, fish, and wildlife, and ensure that southern Idaho is on a path toward a sustainable future.

In eastern Idaho, the Snake River is a blue-ribbon trout river. As it flows west, the river picks up so much pollution that, by the time it reaches Idaho’s western border, it is so contaminated that the State of Idaho warns people not to let their pets swim in it.

For decades the Snake River has been polluted and overallocated, resulting in poor water quality and increasingly declining flows. In some areas, it is now unsafe to recreate in or eat fish from its waters. Additionally, there is virtually no water flowing in some river stretches at times during the year.

From its headwaters in eastern Idaho and Wyoming, the upper tributaries of the Snake River boast some of the best fishing on the planet. Downriver and across the state to the Oregon border, there is a very different situation. The once-mighty river dwindles to a trickle in places. Hot and full of agricultural and other pollution, algae outbreaks, killing fish and prompting warnings for humans and their pets to stay out of the water.

How Does This Happen?

Experts divide water management into two categories: quality (is it safe?) and quantity (is it flowing?). While these categories may make things simpler from a management perspective, they don’t reflect the reality that everything about water is connected. The Snake River is a great example of how water quality and quantity are linked.

The state of Idaho manages the Snake as “two rivers.” The upper Snake is upstream of Milner Dam (located between Twin Falls and Burley in south-central Idaho) and the lower Snake is everything downstream of Milner. This two rivers policy allows for the Snake to literally dry up at Milner Dam. Let that sink in for a minute. The mightiest river in Idaho, and one of the largest rivers in North America, is purposefully dried up every year. Why?

In short, it’s an attempt to satisfy all the water rights that are issued out of the Snake and across the Eastern Snake Plain. More than 80% of these rights are for irrigated agriculture. Spoiler alert: more water rights are issued for water than a typical year provides water for — a situation known as overallocation.

Dilution is the Solution to Pollution — Until There's No River

All along the Snake River, local communities, industries, and people discharge their treated sewage and wastewater into the Snake, relying on the river’s flows to mix with their treated pollution. You may have heard this concept simplified as “dilution is the solution to pollution.” However, when the necessary flows aren’t there, all these discharges contaminate the river. Meanwhile, to try to prevent further contamination, communities (ie., taxpayers) upgrade their wastewater treatment plants to the tune of tens of millions of dollars.

As long as Idaho law and rules allow water quality and water quantity to be governed separately, the never-ending cycle of overallocated water, pollution discharge, and upgrades for wastewater treatments will continue.

Restoring the Snake

ICL recognizes the important role of the Snake River in the life and livelihoods of Idahoans. It is absolutely integral to Idaho’s economy for reasons other than agricultural and industrial needs it. And that’s where we all come in.

ICL’s Snake River campaign is a multi-pronged approach that centers around connecting people and communities to the river in an effort to protect it into the future. We are talking with Idahoans who love the Snake and connecting them with the people who manage it. Together, we will raise our concerns to local, state, and federal policy-makers. We will seek legislative solutions. We will litigate when and if necessary. We will literally clean it up. We will make it possible for future generations of Idahoans to continue to thrive because of the Snake — in a way people have for as long as people have inhabited Idaho.

Together, we will restore the Snake River.

Support Rep. Simpson's Proposal

Write Idaho’s Congressional delegation and Governor Brad Little to demonstrate your support for Congressman Simpson’s proposal. ICL believes it’s a strong starting point as we work to develop solutions together for Idahoans and the people of the Northwest. Urge your family, friends, and community members to speak up for a prosperous future for Idaho.

It’s also important to engage other elected officials at all levels — state legislators, county commissioners, and city councils and mayors — and utility board directors to let them know that this is an opportunity to lead their communities toward a better future as envisioned in Congressman Simpson’s concept.
