Each year, Sequoia and Kings Canyon National Parks establish opening dates for grazing in their wilderness meadows. This allows the parks to protect biological and scenic resources from the impacts that can occur when pack stock graze meadows before soil has dried and plants have developed.
Meadows are most susceptible to pack stock impacts when ground moisture levels are high. Therefore, the parks rely on the amount of winter precipitation (measured in the form of mountain snowpack) as a guide when establishing opening dates. To determine snowpack, the parks and other cooperators of the California Cooperative Snow Surveys Program collect data along a series of snow courses and snow gage sensors.
The parks use the amount of moisture in the snowpack to categorize the year as one of the following:
Dry 50% or less of the average April 1 snowpack
Normal 51% to 150% of the average April 1 snowpack
Wet 151% or more of the average April 1 snowpack
The parks issue two bulletins based on the April 1 and May 1 snowpack measurements in order to allow commercial outfitters, recreational users, and park operations to plan trips in advance. The bulletins update current conditions and anticipated opening dates. They will be posted on this page as they are available in the Current Situation section below.
All bulletins are advisory only. The actual opening dates of specific meadows will be determined in the field.
If you are planning a trip on or near the opening date for a particular area it is your responsibility to contact our Wilderness Office at 559-565-3766 or seki_wilderness_office@nps.gov for the latest update on conditions. More information on planning a wilderness trip using stock can be found on our Wilderness Stock Use webpage.
Current Situation
Snowpack measurements in the parks as of April 5 show that there is approximately 47% of the average snowpack in the San Joaquin and Kings River Drainages, 34% in the Kaweah River Drainage, and 36% in the Kern River Drainage. Snowpack data are available through the California Department of Water Resources.
At this time, the parks are anticipating that opening dates in 2021 will be categorized as a dry year in all drainages. For current park condition information, including COVID-19 safety guidance, please visit our Current Conditions page.
At this time, the we anticipate posting an update in early May.
2021 Opening Dates
This table shows the opening dates in dry years in all drainages. The list is arranged by drainage and travel zone. These dates are only guidelines. Depending on actual conditions, changes in opening dates may be made as the season progresses. If you are planning a trip, it is your responsibility to contact the parks' Wilderness Office for latest condition updates. The office can be reached at seki_wilderness_office@nps.gov or at 559- 565-3766. Changes in opening dates are also posted at www.nps.gov/seki/planyourvisit/stockuse.htm, along with other information important to planning a stock-supported wilderness trip. Check our overnight backpacking web pages for additional information about wilderness travel.
Note that the opening dates only restrict grazing. We permit pack trips prior to opening dates as long as all feed is packed in and stock remain tied to either an existing hitch rail or a “high line” between two trees or rocks on a flat, hard, non-vegetated site away from the meadow, trail, water, and camp.
We appreciate your cooperation in managing stock use in Sequoia and Kings Canyon National Parks. Together we can continue to protect the natural diversity and beauty of the Sierra wilderness.
