Scoping Summary Report: Development Of Lower Basin Shortage Guidelines And Coordinated Management Strategies For Lake Powell And Lake Mead, Particularly Under Low Reservoir Conditions, U.S. Department Of The Interior, Bureau Of Reclamation
All U.S. Government Documents (Utah Regional Depository)
The Bureau of Reclamation (Reclamation) acting on behalf of the Secretary of the Department of the Interior (Secretary) proposes to take action to adopt specific Colorado River Lower Basin shortage guidelines and coordinated reservoir management strategies to address operations of Lake Powell and Lake Mead, particularly under low reservoir conditions. This proposed Action will provide a greater degree of certainty to all water users and managers in the Colorado River Basin by providing more detailed guidelines for the operation of Lake Powell and Lake Mead and by allowing water users in the Lower Basin to know when, and by how …

Record Of Decision: Operation Of Flaming Gorge Dam Final Environmental Impact Statement, U.S. Bureau Of Reclamation
All U.S. Government Documents (Utah Regional Depository)
The Bureau of Reclamation (Reclamation) has completed a final environmental impact statement (EIS) on the operation of Flaming Gorge Dam. The EIS describes the potential effects of modifying the operation of Flaming Gorge Dam to assist in the recovery of four endangered fish, and their critical habitat, downstream from the dam. The four endangered fish species are Colorado pikeminnow (Ptychocheilus lucius), humpback chub (Gila cypha), razorback sucker (Xyrauchen texanus), and bonytail (Gila elegans). Reclamation would implement the proposed action by modifying the operations of Flaming Gorge Dam, to the extent possible, to achieve the flows and temperatures recommended by participants …

All U.S. Government Documents (Utah Regional Depository)
The Chief of the U.S.Department of Agriculture Forest Service has identified invasive species as one of the four critical threats to our Nation’s ecosystems. In response to this national threat,we have evaluated the role of the Forest Service as a leading forest research, forest health, and Federal resource management agency.We are aware of our significant role in addressing invasive species threats at the local, State, and national levels, as well as internationally.We have found the best opportunity for success comes from working strategically, using all our scientific, management, and partnership resources in unison. This document is not designed to serve …
Final General Management Plan/Environmental Impact Statement (Visitor Management And Resource Protection Plan) Zion National Park, Utah, U.S. Department Of The Interior, National Park Service
Final General Management Plan/Environmental Impact Statement (Visitor Management And Resource Protection Plan) Zion National Park, Utah, U.S. Department Of The Interior, National Park Service
All U.S. Government Documents (Utah Regional Depository)
The purpose of this conceptual plan is to describe the general path the National Park Service intends to follow in managing Zion National Park over the next 20 years. The approved plan will provide a framework for proactive decision making on such issues as visitor use, natural and cultural resource management, and park development, which will allow park managers to effectively address future problems and opportunities. In most cases, new development outside the park would take place to meet visitor needs.
Management Guidelines For Sage Grouse And Sagebrush Ecosystems In Nevada, Bureau Of Land Management
Management Guidelines For Sage Grouse And Sagebrush Ecosystems In Nevada, Bureau Of Land Management
All U.S. Government Documents (Utah Regional Depository)
These management guidelines and supportive background information promote the conservation of sage grouse (Centrocercus urophasianus) and their sagebrush (Artemisia spp) habitats on Nevada public lands administered by Bureau of Land Management (BLM). The guidelines are intended to provide interim guidance to field managers, without restricting options currently being explored for regional, state, and local sage grouse/sagebrush conservation planning. The guidelines are a Nevada BLM, habitat-specific, adaptation of the recently updated, and soon to be finalized, Western Association of Wildlife Agencies (WAFWA) Draft Guidelines. The Nevada BLM guidelines apply the most current sage grouse science to BLM activities, within the context …

A Management-Oriented Classification Of Pinyon-Juniper Woodlands Of The Great Basin, Neil E. West, Robin J. Tausch, Paul T. Tueller, United States Department Of Agriculture, Forest Service, Rocky Mountain Research Station
All U.S. Government Documents (Utah Regional Depository)
Pinyon-juniper woodlands occupy about 18 percent (7.1 million ha, 17.6 million acres) of the land area of the Great Basin (Tueller and others 1979). The associated tree species are found over a wide range of environmental conditions extending from communities representative of the upper fringes of the Mohave Desert to communities found at the lower fringes of high mountain forests. Over this spatial and elevational range, communities associated with pinyon-juniper woodlands are highly variable, with complex distribution and compositional patterns. This variability is due to climatic changes occurring over the last 10,000 years and to variation in current environmental conditions …
Final Environmental Impact Statement For Management Of The High Uinta Wilderness, Usda Forest Service
Final Environmental Impact Statement For Management Of The High Uinta Wilderness, Usda Forest Service
All U.S. Government Documents (Utah Regional Depository)
The Final Environmental Impact Statement analyzes four alternatives to amend the Ashley and Wasatch-Cache National Forest Land and Resource Management Plan (Forest Plan) to include Desired Future Condition for mapped Condition Classes with accompanying indicators and standards for the High Uintas Wilderness. The No Action Alternative is analyzed in depth also. Significant issues considered include effects of human overuse on ecosystem components, the extent visitor experience is impacted by rules and regulations, the extent visitor solitude is impacted by other users, structures, and resource impacts, the extent trails meet wilderness objectives, the threat of human and animal waste to water …

Canyonlands National Park And Orange Cliffs Unit Of Glen Canyon National Recreation Area Environmental Assessment For Backcountry Management Plan, National Park Service
Canyonlands National Park And Orange Cliffs Unit Of Glen Canyon National Recreation Area Environmental Assessment For Backcountry Management Plan, National Park Service
All U.S. Government Documents (Utah Regional Depository)
Whether on foot, bicycle, horseback, or in vehicles, most visitors come to Canyonlands National Park (Canyonlands) to experience solitude or to "get away from people." Yet visitation to Canyonlands has risen exponentially over the past five years (Figures 1 and 2). Visitation is expected to continue to rise. As a function of this increase in number of visitors, adverse impacts to Canyonlands' resources have increased and the visitors' ability to find solitude has decreased. Since the mandate of the National Park Service (NPS) is to balance visitor access to the parks with preservation and protection of natural and cultural resources, …
