This page contains a wide range of documents related to the Merced River Plan, with the most recent documents listed first. The National Park Service prepared the initial Merced Wild and Scenic River Plan in August 2000. After multiple lawsuits and litigations, the U.S. Court of Appeals for the Ninth Circuit issued an opinion on March 27, 2008, expanding the scope of what the NPS had previously understood must be included in a legally valid Merced Wild and Scenic River Comprehensive Management Plan. Public scoping on the new Merced River Plan was initiated and over the course of numerous years many documents were compiled throughout this complicated planning process.
Merced Wild and Scenic River Draft Comprehensive Management Plan and Environmental Impact Statement (January 2013)
The Draft Merced River Plan/EIS was released on January 8, 2013. Originally, the 100-day comment period was slated to close on April 18, 2013. In response to several requests for an extension, the comment period was extended through April 30, 2013. The NPS hosted ten public meetings and four webinars. The NPS received 4,098 individual unique correspondences and 25,302 form letters.
The Merced Wild and Scenic River Draft Comprehensive Management Plan and Environmental Impact Statement is a complex publication, derived from a sophisticated and lengthy planning process. The Merced River Draft Plan is made up of more than 2,500 pages broken into 13 chapters and 15 appendices. It contains sets of maps and conceptual site plans prepared for common-to-all actions and for each alternative. Depending on your viewing preference, you can view the Merced River Draft Plan by volume or by chapter.

Draft Merced River Plan/EIS Public Meeting Documents (Winter/Spring 2013)
The Draft Merced River Plan/EIS was released on January 8, 2013. The NPS hosted ten public meetings and four webinars.
Draft Merced River Plan/EIS Factsheets (Winter 2013)
After the spring 2012 workshops, the Yosemite Planning Division engaged the public through webinars, public meetings, and the release of documents.
Preliminary Alternative Workshops (Spring 2012)
The MRP Spring 2012 Preliminary Alternative Concepts Workshops were aimed to allow participants to examine a range of potential visitor experiences designed to be protective of river values. The final plan will guide the care and protection of the Merced River for the next 15 to 20 years. A workbook helped prepare the public to attend one of our four public workshops and two webinars.
Merced River Planning Workbook and Workshops (2011)
In 2011, workshops were held to identify options to protect river values.
Science Forum and Workshops (Spring 2011)
Yosemite National Park's Merced River Plan (MRP) team hosted a series of workshops and a science forum in the spring of 2011. These workshops were a chance to find out more about the conditions of the river's Outstandingly Remarkable Values (ORVs) and management considerations that need to be addressed in a successful Merced River Plan. The workshops focused on transportation, user capacity, and the Merced River's ORVs.
Hydrology, Biology, and Geology Workshop
This workshop focused on the biologic, hydrologic and geologic outstandingly remarkable values (ORVs) of the Merced Wild and Scenic River. Presenters identified the major issues that have arisen due to past and present uses. To examine specific issues pertaining to free flow of the river a park hydrologist discussed removal of large, woody debris, accelerated riverbank erosion, and the disrupted connectivity between the river and floodplain. Additionally, a park botanist identified impacts and stressors to meadows including social trails, ditches and invasive species and will discuss potential management actions and ecological restoration.
The purpose of this workshop was to gain a common understanding of transportation issues and constraints and how these may affect river values. The Merced River Plan identifies opportunities for different types of transportation options that provide visitor access while offering a quality experience and protecting river values. The workshop provided the public with the opportunity to participate in discussions about the various transportation and related access options that were going to be considered in the plan and how these may affect river values and their experiences.
The workshop showcased research, modeling and other information related to transportation considerations that will inform the development of the Merced River Plan.
Cultural Resources Workshop
This workshop presented scientific and legal information about the cultural resources ORVs within the Merced Wild and Scenic river corridor. The workshop also included an update on the overall planning process, and followed with presentations and facilitated discussions specific to the cultural resources ORVs that provide the following:
User Capacity Workshop
This workshop outlined how the National Park Service will meet Wild and Scenic River Act requirements to address user capacity, or the kinds and amounts of visitor use that can be accommodated in the Merced River corridor without negatively affecting river values. Foundational aspects of this process were discussed along with engaging the public in first hand case examples. Relevant science and information was brought to bear on this important topic to illustrate how user capacity was going to be addressed the planning effort.
In May 2011 the National Park Service hosted a science forum to provide the results of several research projects commissioned by the Merced River Plan. These studies were intended to expand the park’s existing knowledge of the Merced River's water quality, its free-flowing condition, and its Outstandingly Remarkable Values (those values that merit the river's designation as wild and scenic, pursuant to the Wild and Scenic Rivers Act).
The purpose of this workshop is to develop a common understanding of recreation activities and related resource protection along the Merced River. A social scientist along with other park planners, scientists, and operations specialists will present an overview of current recreation conditions and managerial considerations. The conversations generated in this workshop will provide a foundation for dialog between park managers and the public as the Merced River Plan is developed.
Outstanding Remarkable Values (ORVs) (2010-2011)
Public Scoping (2007-2010)
The first four documents below summarize the public comments received from 2007 through 2010 on the scope of the new Merced River Plan. The 2007 Public Scoping Comments and the 2009-2010 Public Scoping Comments are unedited compilations of all substantive comment letters the NPS received during those two scoping periods. The file entitled Merced River Plan Public Scoping Comment Summary summarizes the public comments received from both scoping periods; it is intended to be a guide to the major ideas submitted by the public. Comments pertaining to natural and cultural resource subjects were analyzed separately by park staff and are included in the Merced River Plan Public Scoping Comment Summary Supplement.
