  • The Lummi Nation -- WRIA 1 (Mountains to the Sea)
    The Lummi Nation -- WRIA 1 (Mountains to the Sea) WRIA 1 is 1410 square miles in area: 832 square miles of WRIA 1 is in the Nooksack River watershed, the largest single watershed in the WRIA. Forty-nine square miles of the Nooksack watershed is in Canada. It has three main forks: the North, Middle, and South that Bellingham originate in the steep high-elevation headwaters of the North Cascades and flow westerly descending into flats of the Puget lowlands.The North and Middle Forks are glacial rivers and originate from Mount Baker. The South Fork is a snow/rain fed river and Watersheds of originates from the non-glaciated slope of theTwin Sisters peaks. The WRIA 01 Middle Fork flows into the North Fork upstream of where the North Fork confluences with the South Fork to form the mainstem Nooksack River. The mainstem then flows as a low-gradient, low-elevation river until discharging through the Lummi Nation and into Bellingham Bay. Historically, the Nooksack River alternated between discharging into Bellingham Bay, and flowing through the Lummi River and discharging into Lummi Bay (Collins and Sheikh 2002). The Nooksack River has five anadromous salmon species: pink, chum , Chinook , coho, sockeye; and three anadromous trout: steelhead, cutthroat and bull trout (Williams et al. 1975; Cutler et al. 2003).

  • Mitigating Total Flood Impacts Through Intentional Flooding in Agricultural Land Along the Lower Nooksack River
    Mitigating Total Flood Impacts through Intentional Flooding in Agricultural Land along the Lower Nooksack River Alex Sundell, Sam Ripley, Zhuoran Duan, & Francesca White Association of State Floodplain Managers Conference 2014 Abstract: The purpose of this study is to examine the flooding patterns within the Nooksack River Basin in Whatcom County, Washington, in order to design and recommend changes to flood management strategies. Focusing on Reach 2 and Reach 3, defined by the Lower Nooksack River Comprehensive Flood Hazard Management Plan, flooding occurs predominantly in agricultural land, as well as urban land within portions of Ferndale. In order to mitigate this flooding, the proposed strategy consists of intentionally flooding designated areas and storing floodwaters. By analyzing the example hydrograph of the November 30th, 1995 flood event, we observe approximately 9,200 cfs exceeded the flood flow corresponding to Ferndale’s levee gauge height of 19 feet. In order to accommodate and redistribute these flows to prevent damage downstream, a conceptual storage layout is presented as an example of how storage areas could be chosen. Approximately 4,670 acre-feet of land could be used to store floodwaters in the conceptual storage scenario. This study recognizes that peak flow reduction depends on the capacity of chosen storage areas, and a more detailed study would be required to determine the most feasible layout. This strategy offers benefits such as relief of levee breaching, stored water that could be used during drier seasons, reduced risk of crop loss, and replenishment of nutrients and groundwater to surrounding aquifers. Funding for infrastructure modifications can come from shifting City of Ferndale flood capital investment upstream, which will still mitigate downstream by reducing total flow.

  • Nooksack River Transboundary Collaboration Group: 2018-2019
    Nooksack River Transboundary Technical Collaboration Group 2018-2019 Annual Report Final Draft July 2019 Executive Summary The Nooksack River watershed spans part of the border between British Columbia (BC) and the State of Washington (WA). In August 2018, the international, multi-agency Nooksack River Transboundary Technical Collaboration Group (TCG) was established to implement a three-year work plan to reduce fecal bacteria concentrations in the Nooksack River watershed. As a work plan deliverable, the TCG produced this annual report summarizing first year project activities. During the past year, BC and WA sampled surface water throughout the Nooksack watershed, including sites located at the international border. Analysis of BC E. coli data shows that the 2018 wet season geometric means met the BC Primary Recreation guideline throughout the BC portion of the watershed. For four waterways spanning the international border, BC and WA data analysis noted higher fecal coliform concentrations in Cave and Bertrand Creeks as compared to Pepin and Fishtrap Creeks. Higher fecal coliform and E. coli concentrations typically take place during the wet season when soils are saturated or following significant rainfall events. While the Bertrand Creek’s annual fecal coliform geometric mean increased due to high bacteria counts captured in winter 2018-2019, data trends in WA’s lower Fishtrap and Bertrand Creeks and in the Nooksack River mainstem show a decline in longer term fecal coliform concentrations since 2015. The Nooksack River is the largest freshwater source to Portage Bay and to the Lummi Nation’s Portage Bay shellfish growing area. From 2014-2016, portions of the Portage Bay growing area experienced a series of harvest restrictions due to poor water quality conditions.

  • Lower Nooksack River Geomorphic Assessment APPENDIX a Geologic
    February 11, 2019 Lower Nooksack River Geomorphic Assessment APPENDIX A Geologic and Geomorphic History Submitted by: Prepared for: Element Solutions Whatcom County Flood Control Zone District 909 Squalicum Way, Ste 111 322 N Commercial Street, Suite 120 Bellingham WA 98225 Bellingham, WA 98225 REPORT SUBMISSION: Element Solutions Paul Pittman LG Appendix A: Geologic and Geomorphic History Executive Summary A late Holocene avulsion of the Nooksack River abandoned the connection between the Nooksack and Fraser Rivers and established a new course down a former glacial outwash channel. The avulsion was a significant disturbance and the residual effects from this event are apparent in today’s geomorphic conditions. The avulsion has influenced modern-day channel morphology, floodplain morphology, and sediment transport processes. As the river continues to evolve post-avulsion, geologic context should be considered in the development of river management strategies so that continued evolutionary trends are incorporated as natural processes uniquely present on the Nooksack River. Geologic Background The North Cascade Range creates the geologic backdrop of the Nooksack River watershed. The watershed covers over 800 square miles, with more than half the drainage area in the steep Cascade Mountains and foothills. The Nooksack River is a gravel bed river throughout most of its total length. Three primary forks of the Nooksack River exit the Cascades Mountains and converge near the western edge of the Cascade foothills near Deming. The North and Middle Fork Nooksack drainages are fed by the glaciers of the west and north flanks of Mount Baker and adjacent peaks. The South Fork Nooksack drains the foothills of the Twin Sisters Mountains and the southwest foothills of Mount Baker.
