Established by proclamation on May 25, 1907 by President Teddy Roosevelt covering 221,324 acres along the river along the Owens River.  First established to secure the water interests of the City of Los Angeles, the Inyo National Forest has been expanded and contracted at least four times since its creation. Most of the original lands designated as the Inyo National Forest are no longer part of the Forest and are now owned by the Los Angeles Department of Water and Power.  These lands were later returned to the public domain and portions of the Sierra National Forest, east of the Sierra crest as well as the White-Inyo Mountains, were designated as the Inyo National Forest. The forest now covers 2 million acres.  The Inyo National Forest extends 165 miles from Conway Summit in the north and to the Kern Plateau in the south.  The Inyo has over 10,500 feet of elevation difference, from 3,900 feet near Owens Lake to 14,494 on the peak of Mt. Whitney, highest peak in the continental United States. 
  
Established in 1910, the Eldorado National Forest is located on the west slope of the central Sierra NevadaIt ranges in elevation from 1,000 feet in the foothills to more than 10,000 feet above sea level along the Sierra crestA complicated ownership pattern exists. The parcels of other ownership (private or other Agency land) are mostly isolated and surrounded on all sides by National Forest land. An opposite pattern occurs outside of the main forest boundary where several small scattered pieces of National Forest lands are separated from the main body and surrounded by lands of other ownership. The area within the boundary of the forest is 786,994 acres of which 190,270 acres is private or in other government agency ownership.  The remaining 596,724 acres is National Forest land.
+
The Forest includes the Mono Lake National Forest Scenic Area, Boundary Peak - the highest peak in the State of Nevada at 13,140 feet, the world's largest Jeffrey Pine Forest located east of Mammoth Lakes and south of Mono Lake, 2 Wild & Scenic Rivers, 5 Visitor Centers, 3 Scenic Byways, 2 Alpine Ski Areas and 1 Nordic Ski CenterThe world's oldest tree, Methuselah, is a 4700 year old Bristlecone Pine growing in the Ancient Bristlecone Pine Forest atop the White Mountains. The Inyo has 9 Congressionally designated Wilderness Areas covering more than 800,000 acresAmong them is the John Muir Wilderness, which receives the most visitor use per acre, per year, of any wilderness area in the western United States. The Mt. Whitney trail corridor is the most challenging trail to manage in the National Forest System and has the only day use quota and permit requirement on any National Forest.  This land, where the desert meets the mountains, was first reserved for its timber, water and forage. Thanks to decades of public management, the lands of the Inyo National Forest continue to supply clean water to over 3.8 million people, renewable forests, homes for wildlife from Sierra Nevada bighorn sheep to the Golden Trout, and the peace of the outdoors for nearly four million people annually, the most for a National Forest in California.. The Inyo consistently ranks in the top 5 National Forests in the U.S. in recreation use and its developed recreation sites (campgrounds, picnic areas, nature trails interpretive and historical sites, visitor centers, etc) receive the most use of any one National Forest in the country, approximately twice that of the #2 National Forest in this category.
  
The mountainous topography is broken by the steep canyons of the Mokelumne, Cosumnes, American, and Rubicon rivers. Plateaus of generally moderate relief are located between these steep canyons. The principal vegetation types found on the forest are woodland, chaparral, mixed conifer, true fir, and subalpine. A wide variety of hardwoods, brush, grasses, and forbs are mixed in with each of these forest types.  Water is a major resource of the Eldorado National Forest. The average acre on the Forest receives about 56 inches of precipitation annually. Average annual runoff is about 29 inches. This is roughly equal to a yield of 2.4 acre-feet of water per acre of land per year; therefore National Forest lands yield an estimated 1,444,000 acre-feet annually An acre foot of water is equivalent to 325,850 gallons of water, the amount consumed in one year by the average household of 4 people.
+
There are 238,000 acres of old-growth forest on the Inyo National Forest, primarily consisting of Lodgepole pine (''Pinus contorta'') and Jeffrey pine (''Pinus jeffreyi'').
  
Old growth totaling 122,000 acres have been identified in the Eldorado National Forest, consisting of: Douglas-fir (''Pseudotsuga menziesii var. menziesii''), Ponderosa Pine (''Pinus ponderosa''), White Fir (''Abies concolor''), Lodgepole Pine (''Pinus contorta'') and Red Fir (''Abies magnifica'').
+
The forest is divided into the Mono Lake (District 1), Mammoth (District 2), White Mountain (District 3) and Mt. Whitney (District 4) Ranger Districts with the Forest Supervisor's Office in Bishop.
  
An interesting fact about the Eldorado concerns it name.  The spanish words "El Dorado" translate to "the golden one."  Normally el dorado is two words, but the forest has spelled it as one word. The story is told that a clerk accidentally placed a small "d" after El, rather than separating El from Dorado, like the county of a similar name. The Forest Supervisor apparently liked the differentiation and the name "Eldorado" stuck.
 
  
The forest is located within 3 - 4 hours driving time from the San Francisco Bay Area, a metropolitan complex of 4.5 million people. Sacramento is located within 1 - 1 1/2 hours driving time from the forest with a population of over 1,000,000 people.  The forest is divided into the Amador (District 1), Georgetown (District 3), Pacific (District 5) and Placerville (District 6) and  Ranger Districts with the Forest Supervisor's Office in Placerville.

The Eldorado National Forest has 3 nets, Forest, Admin and Service. The Eldorado National Forest uses microwave linked remote bases and has some UHF frequencies allocated to itAt one time there were remote bases on Bald Mtn. (Supervisor's Office and Georgetown RD), Big Hill (Supervisor's Office and Pacific RD), Leek Springs (Supervisor's Office and Placerville RD), Argonaut Hill (UFH linked)(Amador RD), Water Tank (Lumberyard Ranger Station) and winter use of Leek Springs by the Amador Ranger District. The current remote base locations are unknownThere are 11 repeater sites with all three nets at each site.  The Eldorado National Forest does not use channel numbers to describe the frequencies it uses, rather it describes them by name.  Channel plans vary based on the ranger district and function to which they are assignedThe names are shown below under "Description" for each channel.
+
The Inyo National Forest has 3 nets, Forest Net - North, Forest Net - South and Service Net. The Mono Lake and Mammoth Ranger Districts are on the North NetThe White Mountain Ranger District uses the North Net for those areas north of the bottom of the Sherwin Grade on U.S. 395 (McGee and Rock Creek Canyons and the Casa Diablo area east of Crowley Lake) and the South Net south of that point (Buttermilk Country, Bishop Creek and Big Pine Creek to Division Creek as well as the White Mountains (Westguard Pass north).  The Mt. Whitney District uses the South Net only (from Division Creek south to the Kern Plateau and the Inyo Mountains - south of Westguard Pass).  Some areas of Bishop Creek and the north end of the White Mountains are covered by Glass Mountain only (Tone 3) and are exceptions to this North Net/South Net configuration.  Silver Peak, northeast of Bishop in the White Mountains is the only electronic site with repeaters on all 3 nets and is the location of the North Net remote base. The South Net remote base is on Mazourka Peak northeast of IndependenceThe links for the remote bases utilize UHF only.  The Inyo National Forest does not have direct, or simplex channels provided for its 3 Nets.   
  
Direct or simplex communications are not conducted on the forest's repeater nets such as Forest Net.  Tactical frequencies are used instead.  Almost all handheld radios in use by the Forest Service are the Bendix-King.  These radios have 16 groups and 16 channels per group with only one group can be used at a time.  By eliminating the simplex operation of the 5 Forest Service and 3 Cal Fire repeater nets the forest uses, 8 channels are available for other frequencies. The repeater's input tone is transmitted on the output frequency.

The Inyo National Forest fire organization is combined with the Bureau of Land Management (BLM) Bishop Field Office fire organization into one Interagency Fire Management Organization.  The management area combines the public land of the Inyo National Forest and Bishop Field Office in Inyo and Mono Counties in California and part of Mineral and Esmeralda Counties in Nevada, covering over 2 million acres.  The Interagency Fire Management Organization maintains 8 fire stations with 9 engines, 7 fire prevention patrol units, 2 water tenders, a 10-person fire use management hand crew, a 20-person hotshot crew, an air tanker reload base and a helitack base.  This organization, as well as the non-fire management personnel of both agencies, use the two Inyo National Forest nets for its primary nets.  The BLM net is used as an alternate dispatch or command net when multiple fire starts/large incidents occur. 
  
The unit identifier system for non fire management personnel is unknown. At one time it used the district number, '''function number''' and position number system. The functions were numbered as follows: 1 District Ranger, 3 Resources, 4 Recreation, 5 Fuels Management and 7 Timber Management.  The Eldorado National Forest Dispatch Center is co-located with Cal Fire's Camino Interagency Dispatch Center. It also dispatches for the U.S. Forest Service Lake Tahoe Basin Management UnitIt is a 24 hour operation. The Center's call sign is "Camino."
+
In Mono County the wildland fire State Responsibility Area (SRA) inside the Inyo National Forest is in the direct protection area of the Inyo National Forest. This is provided under contract and the state pays the USFS for this service.  The SRA outside the National Forest boundaries in Mono County is in the direct protection area of the BLMIn exchange the BLM land in Inyo County is in the direct protection area of Cal Fire's San Bernardino Unit, Owens Valley Division.  
  
 +
The unit identifiers follow the '''function name''', district number, position number system. Employees working in or out of the Supervisor's Office use identifiers have a "5" following the function name.  The Owens Valley Interagency Dispatch Center is located in the joint Inyo National Forest-BLM Bishop Field Office facility in Bishop.  It also provides dispatch for the BLM Central California District - Bishop Field Office. This center provides dispatching for two National Park Service units:  Devils Postpile National Monument and the Manzanar National Historic Site.  Law enforcement dispatching for Devils Postpile is provided by Yosemite National Park using  a link to its law enforcement net located on Mammoth Mountain. This center is not a 24 hour operation, but is open 7 days per week, year long.  When the Owens Valley Center is shut down the San Bernardino Federal Interagency Communications Center ("San Bernardino") provides dispatching as it is able to control the entire Inyo/BLM radio system. The center's identifier is "Inyo."

Eldorado Lake Tahoe BMU Mendocino San Bernardino Sierra Tahoe


Inyo National Forest (INF - Forest #04) "Inyo" KMB 6-7-0

Established by proclamation on May 25, 1907 by President Teddy Roosevelt covering 221,324 acres along the river along the Owens River. First established to secure the water interests of the City of Los Angeles, the Inyo National Forest has been expanded and contracted at least four times since its creation. Most of the original lands designated as the Inyo National Forest are no longer part of the Forest and are now owned by the Los Angeles Department of Water and Power. These lands were later returned to the public domain and portions of the Sierra National Forest, east of the Sierra crest as well as the White-Inyo Mountains, were designated as the Inyo National Forest. The forest now covers 2 million acres. The Inyo National Forest extends 165 miles from Conway Summit in the north and to the Kern Plateau in the south. The Inyo has over 10,500 feet of elevation difference, from 3,900 feet near Owens Lake to 14,494 on the peak of Mt. Whitney, highest peak in the continental United States.

The Forest includes the Mono Lake National Forest Scenic Area, Boundary Peak - the highest peak in the State of Nevada at 13,140 feet, the world's largest Jeffrey Pine Forest located east of Mammoth Lakes and south of Mono Lake, 2 Wild & Scenic Rivers, 5 Visitor Centers, 3 Scenic Byways, 2 Alpine Ski Areas and 1 Nordic Ski Center. The world's oldest tree, Methuselah, is a 4700 year old Bristlecone Pine growing in the Ancient Bristlecone Pine Forest atop the White Mountains. The Inyo has 9 Congressionally designated Wilderness Areas covering more than 800,000 acres. Among them is the John Muir Wilderness, which receives the most visitor use per acre, per year, of any wilderness area in the western United States. The Mt. Whitney trail corridor is the most challenging trail to manage in the National Forest System and has the only day use quota and permit requirement on any National Forest. This land, where the desert meets the mountains, was first reserved for its timber, water and forage. Thanks to decades of public management, the lands of the Inyo National Forest continue to supply clean water to over 3.8 million people, renewable forests, homes for wildlife from Sierra Nevada bighorn sheep to the Golden Trout, and the peace of the outdoors for nearly four million people annually, the most for a National Forest in California.. The Inyo consistently ranks in the top 5 National Forests in the U.S. in recreation use and its developed recreation sites (campgrounds, picnic areas, nature trails interpretive and historical sites, visitor centers, etc) receive the most use of any one National Forest in the country, approximately twice that of the #2 National Forest in this category.

There are 238,000 acres of old-growth forest on the Inyo National Forest, primarily consisting of Lodgepole pine (Pinus contorta) and Jeffrey pine (Pinus jeffreyi).

The forest is divided into the Mono Lake (District 1), Mammoth (District 2), White Mountain (District 3) and Mt. Whitney (District 4) Ranger Districts with the Forest Supervisor's Office in Bishop.

RADIO SYSTEM

The Inyo National Forest has 3 nets, Forest Net - North, Forest Net - South and Service Net. The Mono Lake and Mammoth Ranger Districts are on the North Net. The White Mountain Ranger District uses the North Net for those areas north of the bottom of the Sherwin Grade on U.S. 395 (McGee and Rock Creek Canyons and the Casa Diablo area east of Crowley Lake) and the South Net south of that point (Buttermilk Country, Bishop Creek and Big Pine Creek to Division Creek as well as the White Mountains (Westguard Pass north). The Mt. Whitney District uses the South Net only (from Division Creek south to the Kern Plateau and the Inyo Mountains - south of Westguard Pass). Some areas of Bishop Creek and the north end of the White Mountains are covered by Glass Mountain only (Tone 3) and are exceptions to this North Net/South Net configuration. Silver Peak, northeast of Bishop in the White Mountains is the only electronic site with repeaters on all 3 nets and is the location of the North Net remote base. The South Net remote base is on Mazourka Peak northeast of Independence. The links for the remote bases utilize UHF only. The Inyo National Forest does not have direct, or simplex channels provided for its 3 Nets.

Other

The Inyo National Forest fire organization is combined with the Bureau of Land Management (BLM) Bishop Field Office fire organization into one Interagency Fire Management Organization. The management area combines the public land of the Inyo National Forest and Bishop Field Office in Inyo and Mono Counties in California and part of Mineral and Esmeralda Counties in Nevada, covering over 2 million acres. The Interagency Fire Management Organization maintains 8 fire stations with 9 engines, 7 fire prevention patrol units, 2 water tenders, a 10-person fire use management hand crew, a 20-person hotshot crew, an air tanker reload base and a helitack base. This organization, as well as the non-fire management personnel of both agencies, use the two Inyo National Forest nets for its primary nets. The BLM net is used as an alternate dispatch or command net when multiple fire starts/large incidents occur.

In Mono County the wildland fire State Responsibility Area (SRA) inside the Inyo National Forest is in the direct protection area of the Inyo National Forest. This is provided under contract and the state pays the USFS for this service. The SRA outside the National Forest boundaries in Mono County is in the direct protection area of the BLM. In exchange the BLM land in Inyo County is in the direct protection area of Cal Fire's San Bernardino Unit, Owens Valley Division.

The unit identifiers follow the function name, district number, position number system. Employees working in or out of the Supervisor's Office use identifiers have a "5" following the function name. The Owens Valley Interagency Dispatch Center is located in the joint Inyo National Forest-BLM Bishop Field Office facility in Bishop. It also provides dispatch for the BLM Central California District - Bishop Field Office. This center provides dispatching for two National Park Service units: Devils Postpile National Monument and the Manzanar National Historic Site. Law enforcement dispatching for Devils Postpile is provided by Yosemite National Park using a link to its law enforcement net located on Mammoth Mountain. This center is not a 24 hour operation, but is open 7 days per week, year long. When the Owens Valley Center is shut down the San Bernardino Federal Interagency Communications Center ("San Bernardino") provides dispatching as it is able to control the entire Inyo/BLM radio system. The center's identifier is "Inyo."
