Ncer Assistance Agreement Annual Progress Report For Grant #83582401 - Assessment Of Stormwater Harvesting Via Manage Aquifer Recharge (Mar) To Develop New Water Supplies In The Arid West: The Salt Lake Valley Example, Ryan Dupont, Joan E. Mclean, Richard C. Peralta, Sarah E. Null, Douglas B. Jackson-Smith Nov 2018

Ncer Assistance Agreement Annual Progress Report For Grant #83582401 - Assessment Of Stormwater Harvesting Via Manage Aquifer Recharge (Mar) To Develop New Water Supplies In The Arid West: The Salt Lake Valley Example, Ryan Dupont, Joan E. Mclean, Richard C. Peralta, Sarah E. Null, Douglas B. Jackson-Smith

Civil and Environmental Engineering Faculty Publications

The goals of the original proposed project remain the same, that is, to test the hypothesis that Managed Aquifer Recharge (MAR) for stormwater harvesting is a technically feasible, socially and environmentally acceptable, economically viable, and legally feasible option for developing new water supplies for arid Western urban ecosystems experiencing increasing population, and climate change pressures on existing water resources. The project is being carried out via three distinct but integrated components that include: 1) Monitoring of existing distributed MAR harvesting schemes involving a growing number of demonstration Green Infrastructure (GI) test sites; 2) Integrated stormwater/vadose zone/groundwater/ ecosystem services modeling; and …


Salmon-Safe Farms, Ellen Southard, Amelia Bahr Apr 2018

Salmon-Safe Farms, Ellen Southard, Amelia Bahr

Salish Sea Ecosystem Conference

Stewardship Partners recognizes the crucial role farmers play in the protection of our watersheds and salmon populations, leading us to implement the Salmon-Safe program in Washington in 2004 to support landowners who are promoting and practicing sustainable land management to combat environmental degradation. To date, we have added more than 100 different Washington State farms and vineyards to the program — ensuring the restoration and maintenance of watershed health across tens of thousands of agricultural acres. Since the major salmon streams in the Puget Sound basin flow through the most productive agricultural valleys, conservation efforts aimed at protecting salmon and …


Listening To Farmers: The Farming In The Floodplain Project, Spencer Easton Apr 2018

Listening To Farmers: The Farming In The Floodplain Project, Spencer Easton

Salish Sea Ecosystem Conference

The Farming in the Floodplain Project (FFP) is an effort to engage farmers in the Clear Creek area, just east of Tacoma, in the planning and design of a multiple-benefit floodplain reconnection project. The foundation of the FFP is to understand and document technical information on the needs of the agricultural community in the area so that those needs can be incorporated into the project. Environmental Science Associates (ESA) conducted technical work on the FFP on behalf of PCC Farmland Trust. Over the course of the FFP, we learned to let the viewpoints of farmers guide how we conducted our …


Soil Conductivity Study And Implications For Fish And Farming Compatibility In The Swinomish Agricultural Area, Nicole Casper, Todd A. Mitchell, Karen J.R. Mitchell, Jason J. Thompson Apr 2018

Soil Conductivity Study And Implications For Fish And Farming Compatibility In The Swinomish Agricultural Area, Nicole Casper, Todd A. Mitchell, Karen J.R. Mitchell, Jason J. Thompson

Salish Sea Ecosystem Conference

The Swinomish agricultural area, along the Swinomish Channel, is part of the Skagit River Delta, a major agrarian region in Puget Sound. Historically a complex system of tidal channels serving as salmon habitat, the tidelands have since been diked and drained. In 2005, the Swinomish Indian Tribal Community (SITC) began restoration to demonstrate compatibility of fish habitat and agriculture. Muted tidal regulators (MTRs) operated to optimize tidal inundation and fish passage, replaced traditional tidegates, and prompted a study to evaluate soil conductivity impacts on agriculture. Objectives included electromagnetic (EM) surveying of soil conductivity, qualitatively assessing EM results utilizing two additional …


Integrating Watershed-Scale And River-Reach Protection And Restoration Planning To Promote Climate Resilience In The South Fork Nooksack River (Sfnr), Oliver Grah, Susan Dickerson-Lange Apr 2018

Integrating Watershed-Scale And River-Reach Protection And Restoration Planning To Promote Climate Resilience In The South Fork Nooksack River (Sfnr), Oliver Grah, Susan Dickerson-Lange

Salish Sea Ecosystem Conference

The Nooksack Indian Tribe reservation is located at the foot of the North Cascades Mountains, approximately 13 miles east of Bellingham, WA and the Salish Sea. The Tribe relies on a harvestable surplus of Pacific salmon in the Nooksack River for cultural, subsistence, and commercial purposes. Today, Pacific salmon runs are less than 10 percent of the runs in the late 1800’s. Causes of the declines are complex; however, it is well understood that the legacy of commercial forestry, agriculture, and development has increased sediment loading and water temperature. Climate impacts will cumulatively add to the legacy impacts, which are …


Integrated Agricultural Riparian Stewardship In The Stillaguamish And Snohomish Watersheds, Kristin Marshall, Cindy Dittbrenner, Carrie Byron, Colin Hume Apr 2018

Integrated Agricultural Riparian Stewardship In The Stillaguamish And Snohomish Watersheds, Kristin Marshall, Cindy Dittbrenner, Carrie Byron, Colin Hume

Salish Sea Ecosystem Conference

The Stillaguamish and Snohomish River watersheds are regionally important to the health of Puget Sound and the Salish Sea and in particular for the recovery of salmon. The habitat gains needed to achieve salmon recovery in these watersheds include much of the agricultural landscape in Snohomish County, a situation that often results in conflicts between salmon recovery and agricultural communities. The Snohomish Conservation District’s National Estuary Program-funded Integrated Riparian Stewardship project is one of several efforts aimed at simultaneously achieving agricultural land preservation and salmon habitat protection and restoration in one of the fastest growing counties in the United States, …


No Farm Is An Island: Pollinators And Pollination In Agricultural Landscapes, Charles C. Nicholson Jan 2018

No Farm Is An Island: Pollinators And Pollination In Agricultural Landscapes, Charles C. Nicholson

Graduate College Dissertations and Theses

Productive, resilient and sustainable agricultural systems are required to meet the immediate needs of a burgeoning human population, while avoiding ecosystem collapse. Agriculture provides food, fiber, fuels and other products for our current population of 7 billion and is still the major livelihood for 40% of people worldwide. By replacing natural habitat and employing chemical inputs, agriculture also negatively impacts biodiversity and impairs the provision of ecosystem services. This poses a challenge for agriculture as these impacted services are often those required for high yielding and high-quality crop production. Evidence is accumulating that agricultural management can safeguard biodiversity and ecosystem …
