EPA - What are the benefits of a Healthy Watershed? 

Why identify and protect healthy watersheds? In many ways, healthy watersheds substantially affect the quality of life for people and the environment overall – often by performing ‘free work’ that communities do not have to do, or pay for, themselves. The beneficial roles of watersheds in healthy conditions can be surprisingly far-reaching and include ecosystem services, economic benefits, and physical and mental health benefits.

How’s My Waterway - Find Your Watershed

EPA resource that provides maps and water quality monitoring results of watersheds based on zip code. Water quality is monitored for physical, chemical, and biological factors. The monitoring results are assessed against EPA-approved water quality standards or thresholds. Water can be impaired, meaning it is not able to be used for certain purposes. The condition of a waterbody is dynamic and can change at any time, and the information in How’s My Waterway should only be used for general reference. If available, refer to local or state real-time water quality reports. 

 

What’s a WRIA?

WRIA stands for Water Resource Inventory Area, which is pretty much the same as a natural watershed. But a WRIA is a legal designation by state law for improving management decisions to support water use for many different human needs, as well as to guide ecological decisions for salmon recovery. There are 62 WRIAs in our state, each defined by a set of higher elevation ridgelines that capture precipitation and funnel rain and snowmelt through smaller subbasins into streams, tributaries, and rivers. On the WRIA pages found at the Washington State Department of Ecology, you can learn more about the key factors affecting water resources in your WRIA. These pages include a great mapping tool, and resources on the history of Water Law in our state.  

 

WRIA 9 - Green-Duwamish and Central Puget Sound Watershed

Chinook salmon, bull trout, and steelhead are listed as threatened under the Endangered Species Act. In this watershed, citizens, scientists, businesses, conservation groups, and governments are working together to respond to the decline of salmon and the lands and waters on which the fish depend. Seventeen local governments collaborated in developing a science-based Salmon Habitat Plan. Read the Executive Summary or download individual chapters from the full Plan. This chapter in particular lays out the Science Foundations for the Salmon Recovery Plan. Carrying out the plan recommendations will protect and restore a healthy watershed ecosystem for both people and fish.

Green River Habitat Conservation Plan - Tacoma Water

This important legal document describes how Tacoma Water plans to minimize and mitigate any “take” that may result from their role in providing water using a diversion dam. An incidental take permit is required to protect threatened or endangered species, and a Habitat Conservation Plan must accompany the permit application. Tacoma Water prepared the Habitat Conservation Plan as part of its application to the U.S. Fish and Wildlife Service and the National Marine Fisheries Service for a 50-year incidental take permit for its water supply operations on the Green River.  

Green Duwamish Watershed - Ecosystem Services Enhanced by Salmon Habitat Conservation

A fascinating report on assessing the economic value of a natural watershed system. The Water Resource Inventory Area 9 (WRIA 9) Habitat Plan is a long-term, comprehensive plan to protect and restore Chinook salmon in the Green/Duwamish and Central Puget Sound Watershed. Restoring salmon has significant socio-economic implications. The greatest socio-economic implication of salmon recovery is in securing healthy ecosystems which provide vast public and private benefits. WRIA 9 ecosystems produce $1.7-6.3 billion dollars of value in goods and services each year, benefiting individuals, communities, businesses, and governments within WRIA 9. The value of salmon restoration and healthy ecosystems to future generations is far greater.  

Cedar River Watershed Habitat Conservation Plan - Seattle Public Utilities

A 50-year, ecosystem-based plan to address declining populations of salmon, steelhead and other fish and wildlife in the Cedar River basin. Prepared under the Endangered Species Act (ESA), the plan is designed both to provide certainty for the City of Seattle's water supply and hydroelectric operations and to protect and restore habitats of fish and wildlife that may be affected by these operations.

 

History of the Cedar River Watershed

The Cedar River watershed has been in use as Seattle’s main water supply since 1901. This has resulted in many changes to the land, water, forests, and animal habitats within the 91,400-acre environment. 

Tolt River Watershed - Seattle Public Utilities

The South Fork Tolt River is the smaller and lesser known (than the Cedar River) but still essential second supply watershed in Seattle Public Utilities' freshwater supply system. Located in the foothills of the Cascades in east King County, it supplies about 30% of the drinking water for 1.4 million people in and around Seattle. The system first came on-line in 1964, and since 1989 has also supported a small Seattle City Light hydro-electric facility. In 1997, the City of Seattle successfully exchanged lands within the South Fork Tolt watershed with Weyerhaeuser Company, giving Seattle 70% ownership (approximately 8,400 acres) of the land that supplies the water. The eastern 30% lies in the Mt. Baker-Snoqualmie National Forest.

International Water Association

Cities are rapidly expanding and water resources are under increasing pressure. We need to find ways to do more with less while ensuring that cities are resilient to floods, droughts, and the challenges of growing water scarcity. Transitioning cities to address these challenges has never been more urgent. The 17 IWA Principles for Water-Wise Cities help city leaders ensure that everyone in their cities has access to safe water and sanitation. One of the aims is to ensure that water is integrated with planning and design in cities to provide increased resilience to climate change, livability, efficiencies, and a sense of place for urban communities. 

 

United Nations Sustainable Development Goals - Water 

While substantial progress has been made in increasing access to clean drinking water and sanitation, billions of people—mostly in rural areas—still lack these basic services. Worldwide, one in three people do not have access to safe drinking water, two out of five people do not have a basic hand-washing facility with soap and water, and more than 673 million people still practice open defecation. A predicted 40 percent shortfall in freshwater resources by 2030, coupled with a rising world population, has the world careening towards a global water crisis. Recognizing the growing challenge of water scarcity the UN General Assembly launched the Water Action Decade March 2018-2028, to mobilize action that will help transform how we manage water.  

 

19 Best Solutions to the Global Freshwater Crisis

Population growth, urban development, farm production, and climate change are increasing competition for fresh water and producing shortages.

Climate Action Through One Water

The water sector is at the forefront of the climate crisis. Intense storms and other extreme weather events, repetitive flooding, very hot and dry conditions and droughts, sea-level rise, and saltwater intrusion are occurring more often and more severely than ever before. Projections indicate we will only see an increase in these events across the nation, with lower-income people, communities of color, and other vulnerable populations hit the hardest. Securing a sustainable water future for all is inextricably tied to our ability to account for, and manage, these new climate realities. The Alliance’s Climate Action through One Water Initiative unites diverse interests in the water sector, including utilities, consulting firms, local government agencies, environmental organizations, community partners, and social practice artists, to address the climate crisis and foster equitable solutions through adaptation, resilience, and mitigation strategies. 

 

UK - Net Zero Emissions in the Water Sector 

Water companies in the UK unveiled a ground-breaking plan to deliver a net-zero water supply for customers by 2030 in the world’s first sector-wide commitment of its kind. They estimate they can save the emission of 10 million tonnes of greenhouse gas by reaching net-zero two decades ahead of the UK Government’s legally binding target of 2050. The goal is to set the bar for other infrastructure, utility and energy-intensive industries in the UK and around the world.
