This GWMP seeks to provide a framework for advancing the level of understanding and for facilitating future coordination regarding management of groundwater resources in the Little Lake Valley. 1.1 Purpose of the Plan This voluntary, non-regulatory GWMP describes existing local groundwater management policies and recommends a range of actions that the City of Willits may take within the boundaries of its legal authority, to monitor, analyze, and interpret characteristics of the Little Lake Valley groundwater basin (Basin). This plan is also intended to identify and develop potential, effective management practices for utilizing and protecting valuable groundwater resources within the Basin. For the purposes of carrying out the goals and objectives established in this GWMP, the boundaries of the GWMP area include all of the land within the City of Willits jurisdictional authority, including the land within the City limits and City-owned properties outside the City limits, as shown on Figure 1-1. Any land outside of the jurisdictional authority of the City of Willits is not included in this GWMP. Although this GWMP is limited to the jurisdictional boundaries of the City of Willits, this GWMP seeks to improve the understanding and sustainable management of groundwater resources in the entire Little Lake Valley, where mismanagement can impact water users within the Little Lake Valley and the surrounding areas. In addition, this GWMP will allow the City of Willits and other entities within the Basin, if they choose to adopt this GWMP, to be eligible for grant funding administered through the Department of Water Resources (DWR) for projects related to groundwater. 1.2 Background and Legal Authority for Local Groundwater Management In early 2019, the City of Willits submitted a preliminary grant application for Integrated Regional Water Management (IRWM) funding, administered by the DWR for a groundwater supply project which would greatly improve drinking water supply reliability for the community, especially in times of drought. The project was selected for funding; however, as outlined in the IRWM Grant Program Guidelines (2019), as a condition for receiving the funding, the City of Willits must commit to adopting a groundwater management plan that meets the requirements of Water Code §10753.7 by September 6, 2020 (within one year of the final grant application submittal date of September 6, 2019). On December 11, 2019, the City of Willits City Council formally approved Resolution No. 2019-59 noticing its intent to prepare a groundwater management plan for the portion of the Little Lake Valley groundwater basin within its jurisdictional authority (resolution of intention). The resolution of intention is included as Appendix A. The development of a groundwater management plan is governed by the Groundwater Management Act, which was codified into law in 1992 as California Water Code (CWC) §10750 et seq. and was subsequently amended in 2002 and 2011. CWC §10750 et seq. allows development of a groundwater management plan by local agencies to efficiently manage and maximize groundwater supplies, assure long term water supplies, and distribute costs, benefits, and water sharing in an equitable manner. Pursuant to CWC § 10753 (a), as a local agency whose service area includes a portion of a groundwater basin, as defined in CWC § 10752, the City of Willits has the legal authority to adopt and implement a groundwater management plan within all or a portion of its service area.

Naturalists had explored the forests of the north coast region and some, including John Mur, were especially impressed by the extraordinary stand of redwoods alongside the South Fork of the Eel River at bull Creek and the nearby Dyerville Flat. These experts agreed that the coast redwood forest was at its magnificent best far to the north of San Francisco. Some authorities went so far as to say that the Bull Creek and Dyerville Flat area supported the most impressive and spectacular forest in the whole world…. In 1916 and 1917 several developments took place that would eventually have a profound impact on the north coast redwood region in general and the Bull Creek-Dyerville Flat area in particular.

    Eel River Recovery Project Final Report: Citizen Assisted 2015-2016 Fall Chinook Salmon Monitoring Prepared for: Eel River Recovery Project By: Patrick Higgins, ERRP Managing Director & Eric Stockwell, ERRP Fall Chinook Project Coordinator With Funding From: Patagonia World Trout Initiative & Salmon Restoration Association Eel River Recovery Project: Final Report 2015-2016 Fall Chinook Salmon Monitoring July 2016 i Acknowledgements The Eel River Recovery Project (ERRP) faced challenging conditions in estimating the 2015- 2016 Eel River fall Chinook salmon run due to extremely low flows in early fall and then very high flows starting in December. ERRP wishes to thank the Wiyot Tribe and Humboldt Redwood Company for once again co-sponsoring the project. The project was made possible by grant funding provided by the Patagonia World Trout Initiative and the Salmon Restoration Association, which sponsors the World’s Largest Salmon BBQ in Fort Bragg. ERRP was assisted by dozens of volunteers who participated in lower Eel River dive surveys and in tracking fall Chinook migrations and spawning throughout the watershed. Only three dives were carried out from late October to mid-November in the lower river and only in the 12th Street Pool because of shallow depths, profuse algae and the risk of divers contracting swimmer’s itch. When November rains remained sparse, ERRP deployed kayaks for lower main Eel River spawning surveys. Results from the Van Arsdale Fish Station and aerial and ground surveys of spawning were shared by fisheries biologist Scott Harris of the California Department of Fish and Wildlife (CDFW). Thanks go out to Park Steiner and PG&E (SEC 2016) for sharing spawning data from the upper Eel River and Tomki Creek, although the latter had no fish sightings this year.

    The Recovery of Aggraded Stream Channels at Gauging Stations in Northern California and Southern Oregon

    189 Erosion and Sediment Transport in Pacific Rim Steeplands. I.A.H.S. Publ. No. 132 (Christchurch, 1981) The recovery of aggraded stream channels at gauging stations in northern California and southern Oregon T.E. Lisle, Forest Service, US Dept. Agric, 1700 Bayview Dr., Arcata, California, 95521, USA. Abstract. Discharge measurements at nine gauging stations in northern California and southern Oregon document episodes of channel bed aggradation lasting 5 to 15 years after the flood of December 1964 to January 1965. Bed elevations rose 1 to 4 m, then gradually declined to a stable level at or above the pre-flood level. Seven gauging sections widened by 7 to 105 per cent during the aggradation episodes. Channels formed within aggraded material narrowed during degradation; in one case, the pre-flood width was attained. Eroded streambanks formed in non-alluvial material rarely advanced because of 1) post-1964 flood flows, 2) the slowness of processes forming non-alluvial streambanks, and 3) the difficulty of establishing riparian vegetation under the conditions of coarse substrate and seasonal rainfall. These results suggest that infrequent large floods are more effective in shaping stream channels in highly erosive terrane with seasonal rainfall than in less erosive humid areas with comparable amounts of annual precipitation.
