Silver Lake Area (OR81)

Area of Known Wolf Activity

Silver Lake wolves AKWA

Current Silver Lake AKWA map (pdf)

Within Areas of Known Wolf Activity (AKWA) certain preventative measures are recommended to minimize wolf-livestock conflicts. Though not required, non-lethal measures are important to reduce depredation. If depredation becomes chronic and lethal control become necessary, ODFW’s ability to lethally remove depredating wolves will be dependent on the extent that non-lethal measures have been used and documented. Information about specific wolf-livestock conflicts can be found on the Wolf and Livestock Updates page.

Previous Silver Lake AKWA maps (for reference only – see above for current map)

Under Phase I management, when ODFW confirms wolf depredation of livestock, an Area of Depredating Wolves (ADW) is designated for the purpose of focusing non-lethal deterrent measures.  In some cases, the ADW may encompass the entire home range of a pack, but in others, it may only encompass a portion.  Within an ADW, certain criteria must be met for an incident of depredation to qualify toward lethal control, see the West Wolf Management Zone page for more information.

Previous Silver Lake Wolves ADW maps (for reference only – there is no currently designated ADW)

Under Phase I management, an area specific wolf-livestock conflict deterrence plan (CDP) is prepared for an area designated to be an ADW.  The CDP will help livestock producers identify the appropriate non-lethal measures which are effective in a given circumstance.  See the West Wolf Management Zone page for more information.

February 4, 2022 – The original Silver Lake wolves (OR28, OR3) are no longer present.  The ADW and CDP have been discontinued.  Wolf OR81 is still present and a new AKWA is designated showing the area she has been using.  Two other wolves are also currently using the Silver Lake Wildlife Management Unit, see LAS13/OR115.


April 21, 2021 – Two wolves were documented at the end of the year.  No reproduction was documented during 2020.


April 15, 2020 – A female wolf was radio-collared in November, 2019.  No reproduction was documented during 2019.  Another wolf was  documented with her during the 2019 winter count.


April 8, 2019 – One wolf was documented during the 2018 winter count.


April 12, 2018One wolf was documented during the 2017 winter count.

April 10, 2017 OR3 and OR28 paired and bred in 2016, the pair produced at least one pup.  OR28 was found dead in October 2016.  One large wolf has been documented in the area this winter, but the status of the pup is unknown.


October 24, 2016 – ODFW designates an Area of Depredating Wolves and posts a Conflict Deterrence Plan for the Silver Lake Wolves.

October 14, 2016 - U.S. Fish and Wildlife Service News Release - $5,000 Reward Offered for Information on Illegal Killing of Gray Wolf Near Summer Lake, Oregon

The U.S. Fish and Wildlife Service is offering a $5,000 reward for information leading to the arrest of the person(s) responsible for killing a federally protected gray wolf in south-central Oregon. On Oct. 6, 2016, a radio collared female gray wolf known as OR28 was found dead in the Fremont-Winema National Forest near Summer Lake, Oregon.

July 28, 2016ODFW and USFWS have confirmed that OR3 (an eight-year-old male originally from the Imnaha pack) has paired up with OR28, a three-year-old GPS radio-collared female originally from the Mt Emily pack.  Based on remote camera images, the two are believed to have produced at least one pup in 2016.  They are primarily using the Silver Lake Wildlife Management Unit in western Lake County and have been dubbed the Silver Lake wolves.  (A group of wolves is designated a pack when there is evidence of a minimum of four wolves traveling together in winter.)

Wolf OR3 dispersed from northeast Oregon’s former Imnaha Pack in 2011, just a few months before more well-known wolf OR7.  But unlike OR7, OR3 had a VHF collar not a GPS collar.  VHF collars do not automatically transmit location information and wildlife managers lost track of him after the fall of 2011.   OR3 made a brief reappearance in the Cascades in northern Klamath County in summer 2015.  His radio-collar is no longer functional.  It is unknown if OR3 bred before this year.

March 4, 2016 – From the 2015 Oregon Wolf Conservation and Management Annual Report

In early November 2015, a 2-year-old radio-collared female wolf (OR28) dispersed from the Mt Emily pack in Umatilla County. By Nov. 19, OR28 arrived into the area she continued to use in the Fort Rock and Silver Lake Units of Klamath and Lake County. She has been observed repeatedly with a male wolf.
