FOREWORD
This publication makes available to cooperators of the California Cooperative
Snow Survey Program and other parties concerned with snow hydrology a complete up-to-
date SUMMARY of HISTORICAL SNOW COURSE DATA,
The first summary of snow survey measurements in California was published in
December 1959 *nd presented all the snow course data on record with the Department of Water
Resources as of that date. Preparation of that summary included the investigation and
analysis of all the original data for each snow course, with the objectives of standardizing
sampling procedure and determining the optimum number of sample points per course. Whenever
possible, snow courses were revised if they did not conform with the criteria established
BY THE studies. WheN REVISIONS WERE MADE, THE NOTES WERE RECOMPUTED FOR THE ENTIRE PERIOD
OF RECORD TO ASSURE HOMOGENEITY OF THE PUBLISHED RECORDS. AlL REVISED SNOW COURSES WERE
SUBSEQUENTLY MEASURED IN ACCORDANCE WITH THE REVISIONS. THIS PUBLICATION NOT ONLY PROVIDED
A COMPREHENSIVE ANALYSIS OF HISTORICAL DATA FOR EACH SNOW COURSE IN CALIFORNIA, BUT ALSO
PROVIDED A MORE RELIABLE BASIS FOR VARIOUS SNOW HYDROLOGY STUDIES.
The PREPARATION OF THIS SUMMARY, WHICH SUPERSEDES THAT PUBLISHED IN 1959, IS ONE
OF THE CONTINUING ACTIVITIES OF THE CALIFORNIA COOPERATIVE SnOW SURVEY PROGRAM. THROUGH THIS
PROGRAM, THE DEPARTMENT OF WATER RESOURCES, AS COORDINATOR OF PROGRAM ACTIVITIES, DISCHARGES
ITS OBLIGATIONS OF GATHERING AND CORRELATING INFORMATION AND DATA PERTINENT TO FORECASTING
OF SEASONAL WATER CROP AS SET FORTH IN SECTION 228, ARTICLE 2, CHAPTER 2, DIVISION 1, OF
THE Water Code:
"The Department shall gather and correlate information and data pertinent
to an annual forecast of seasonal water crop, including the making of snow surveys
either independently or in cooperation with any person or any county, state, federal,
or other agency. "
Data presented in this summary include only snow surveys taken by standard
METHODS. Data obtained from snow stakes, aerial snow depth markers, or radioactive snow
GAGES ARE NOT INCLUDED. WHEN NO SNOW DATA ARE PRESENTED FOR A GIVEN MONTH AND YEAR,
IT INDICATES THAT EITHER NO MEASUREMENT WAS MADE OR THAT THERE IS NO ZERO MEASUREMENT ON FILE
WITH THE Department. The data tables in this summary are in order of hydrographic area,
STREAM BASIN, AND BY ELEVATION OF SNOW COURSES WITHIN THE BASIN. ThE SNOW COURSES ARE
cross-indexed BY STREAM BASIN, COURSE NUMBER, AND ALPHABETICALLY BY SNOW COURSE NAME ON
PAGES 5 TO ^6 OF THIS REPORT. LOCATION OF STREAM BASINS AND SNOW COURSES ARE SHOWN ON
Plates 1 to I5.
Current snow course data are published in supplements of Bulletin 120,> "Water
Conditions in California". These bulletins are prepared as of the first of each month
from February through May of each year and may be obtained by request to:

HISTORY OF SNOW SURVEYS IN CALIFORNIA
Snow surveying in the Western United States was introduced by Dr. James E.
Church of the University of Nevada shortly after the turn of the century in an effort to
gather information on the effects of mountains and forests upon conservation of snow.
About 1909« Dr. Church developed the Mt. Rose Snow Sampler and Scale which, though slightly
modified, have remained the basic tools of the snow surveyor. The first formal snow courses
WERE MEASURED IN 1910 IN THE AREA NEAR LaKE TaHOE.
The application of snow survey data to forecasts of runoff was developed by
Dr. Church and his associates as a result of studies of the water level rise of Lake Tahoe.
Waters of the lake, which are controlled for power, irrigation, and municipal use, often
flooded the lakeshore area during the snowmelt period. In 1909* AN ultimatum was issued
BY THE LAKESHORE DWELLERS TO THE OPERATING POWER COMPANY THAT TaHOE MUST BE LOWERED
SUFFICIENTLY EACH WINTER TO PRECLUDE ALL POSSIBILITY OF SPRING FLOODING. ThuS IT BECAME
necessary to find a method of accurately predicting the spring rise in water level
elevation. a good correlation was found between the late-season water content of snow on
Mt. Rose and spring rise of the lake. Forecasts of spring rise of Lake Tahoe were subsequently
IMPROVED by using ADDITIONAL SNOW MEASUREMENTS AT OTHER LOCATIONS IN THE BASIN.
The State of California early recognized the potential value of runoff fore-
casts TO irrigation interests in the Sacramento and San Joaquin Valleys. Through efforts
OF the late Major Paul M. Norboe, Chief Assistant State Engineer, the California Department
OF Engineering in 191? was authorized by the State Legislature to engage in snow surveying.
In cooperation with the State of Nevada, snow surveys were carried on by the Department for
several years in the watersheds of the Yuba, Truckee, Carson, and Walker Rivers. In 1923,
this work was discontinued as a State of California activity because of a lack of funds.
Snow surveying, however, was continued by the State of Nevada and private agencies
interested in the program.
The return to snow surveying in 1929 by the State of California was the
RESULT of efforts OF THE CALIFORNIA ECONOMIC RESEARCH COUNCIL OF THE StATE CHAMBER Of
Commerce. The California Legislature in that year appropriated $15,000 to organize
AND carry out A SNOW SURVEY PROGRAM. ThIS FUNCTION WAS ASSIGNED TO THE DIVISION OF
Water Resources, the successor to the Department of Engineering. During the summer and
FALL OF 1Q29> 150 snow courses were established throughout the Sierra, from the Upper
Sacramento River Basin on the north to the Kern River Basin on the south. Equipment
was obtained, shelter cabins were prepared, and arrangements were completed for the
SURVEYS TO be MADE, MuCH OF THIS WORK WAS DONE THROUGH TVIE COOPERATION OF AGENCIES
SUCH AS PUBLIC UTILITIES AND IRRIGATION DISTRICTS WHOSE EMPLOYEES ALSO MEASURED MANY OF
THE COURSES. A "MONTHLY BULLETIN OF SnOW SuRVEY AND PRECIPITATION DATa" WAS ISSUED BY
THE State on February 1, I93O, marking the first of a series of publications of snow
SURVEY DATA AND FORECASTS OF RUNOFF WHICH HAVE BEEN ISSUED NEARLY EVERY YEAR SINCE
that DATE. Since ^^'^^, these bulletins have been titled "W^ter Conditions in California",
AND BEGINNING IN 19^3 HAVE BEEN DESIGNATED BULLETIN No. 120. ThE FIRST FORECASTS OF
UNIMPAIRED April-July runoff were issued in April IQ30. However, these early forecasts
WERE POSSIBLE FOR ONLY THE FEW RIVER BASINS IN WHICH SNOW SURVEYS BEGAN EARLY ENOUGH TO
TEVELOP SUFFICIENT BACKGROUND DATA.
For THE YEARS 193't AND 1935, NO FUNDS WERE AVAILABLE TO CONTINUE THE PROGRAM.
Fortunately, during this period, many cooperating agencies continued to make surveys
USING State equipment, which was permitted to remain in the field; thus the disconti-
nuity OF RECORDS WAS NOT AS GREAT AS MIGHT HAVE BEEN ANTICIPATED. As THE RESULT OF A 1935
APPROPRIATION BY THE CALIFORNIA LEGISLATURE, THE CALIFORNIA COOPERATIVE SnOW SuRVEY PROGRAM
AS A State coordinated activity was resumed in 193^- Even though appropriations were only
ABOUT one-half OF THE FORMER AMOUNT, THE PROGRAM WAS RE-ESTABLISHED THROUGH GREATER CONTRI-
BUTIONS on part OF THE COOPERATING AGENCIES.
Subsequent to 1936, the California Cooperative Snow Survey Program has remained
CONTINUOUSLY ACTIVE. ThE ORIGINAL NETWORK OF SNOW COURSES HAS BEEN EXPANDED TO COVER ALL
MAJOR SNOW AREAS OF THE STATE. OvER 300 SNOW COURSES ARE PRESENTLY SCHEDULED FOR MEASUREMENT
ON April 1, with about 200 on February 1, l80 on March 1, and 110 on May 1. The number of
PUBLIC and private AGENCIES ACTIVELY PARTICIPATING IN THE PROGRAM NOW NUMBER 39- APPROXI-
MATELY 150 SNOW SURVEYORS ARE INVOLVED IN THE PROGRAM, REPRESENTING THE STATE, POWER COMPANIES,
IRRIGATION DISTRICTS, THE U. S. FOREST SERVICE, THE NATIONAL PaRK SERVICE, AND MANY OTHER
local and private agencies. although snow courses are actually measured by many cooperators,
all information is funneled into the office of the department of water resources where the
data are assembled and forecasts of runoff are prepared for publication in department of
Water Resources' Bulletin No. 120, "Water Conditions in California".
Basic snow survey methods have remained virtually unchanged since 191O,
ALTHOUGH SOME OF THE THEORY BEHIND SAMPLING HAS CHANGED RADICALLY. THE TREND HAS BEEN
toward greater AREAL coverage with less INTENSIVE SAMPLING. NoW MOST SNOW COURSES IN THE
State have only about ten sample points in contrast to the ko or 50 sample points which many
OLDER courses HAD.
While much progress has been made in the development of automated snow measure-
ment equipment (such as radioactive snow gages and "snow pillows"), the Mt. Rose type sampler
remains the most important snow measuring device. Even with increasing use of aerial snow
DEPTH markers, the WATER CONTENT OF THE SNOWPACK IS STILL BASED ON DATA OBTAINED AT KEY
courses WITH EQUIPMENT ESSENTIALLY THE SAME AS DEVELOPED BY Dr. ChuRCH NEARLY A HALF A
CENTURY AGO. HoWEVER, THE EXPANSION OF THE AERIAL SNOW DEPTH MARKER P.^OGRAM MAS GREATLY
FACILITATED THE GATHERING OF SNOW DATA, ESPECIALLY IN REMOTE AREAS OF THE STATE. In SOME
BASINS, BEGINNING IN 1965. THE EARLY-SEASON SURVEYS WILL BE LIMITED TO ONLY A FEW KEY
SNOW COURSES. FORECASTS WILL BE BASED ON THESE MEASUREMENTS, SUPPLEMENTED BY SNOW DEPTHS
OBTAINED AT THE REMOTE AERIAL MARKER SITES. THE RAPIDITY WITH WHICH THESE DATA CAN BE
GATHERED, NOT ONLY WILL PROVE ADVANTAGEOUS IN MAKING THE REGULAR MONTHLY FORECASTS, BUT
ALSO WILL MAKE FEASIBLE THE REVISION OF FORECASTS NEGATED BY STORMS OCCURRING AFTER THE
COMPLETION OF SCHEDULED SURVEYS.

HISTORY OF SNOW SURVEYS IN CALIFORNIA
Snow surveying in the vycsTERN United States was introduced by Dr. James E.

develop sufficient background data.

GLOSSARY OF TERMS
This Glossary of Terms is composed of definitions as used in this summary and in
THE Bulletin No. 120 series of reports entitled "Water Conditions in California".
AVERAGE WATER CONTENT — The average April 1st water content of a snow course, computed for the
30-YEAR period ^^'i^ -^960. Averages for snow courses with less than 30 years of record
have been determined by comparison with courses with complete records. However, all
averages are based upon a minimum of seven years of record. averages have been adjusted
to compensate for precipitation occurring between april 1 and the date of measurement.
BASIN (Stream Basin) — The entire watershed of a stream above the gaging station or forecast
POINT. Each hydrographic area in the State is broken down into stream basin units for
BETTER DEFINITION OF AREAS. THE STREAM BASIN NUMBER IS A NUMBER ASSIGNED GEOGRAPHICALLY
TO THE STREAM BASIN TO SIMPLIFY MACHINE SORTING AND IDENTIFICATION. ThE FIRST DIGIT
REPRESENTS THE HYDROGRAPHIC AREA; THE SECOND TWO DIGITS REPRESENT THE STREAM BASIN.
CALIFORNIA COOPERATIVE SNOW SURVEY PROGRAM — The program by which snow surveys and allied
activities are accomplished in California. The State Department of Water Resources is
THE coordinating AGENCY FOR CALIFORNIA'S PROGRAM. AGENCIES CURRENTLY COOPERATING IN THE
PROGRAM BY MAKING SURVEYS OR FURNISHING FUNDS ARE LISTED ON PAGE VII OF THIS REPORT.
CALIFORNIA SNOW COURSE NUMBER — An arbitrary number assigned to a snow course to facilitate
IDENTIFICATION OF DATA PERTAINING TO THAT COURSE. THE SNOW COURSE NUMBER IN COMBINATION
WITH THE STREAM BASIN NUMBER IS USED TO IDENTIFY THE COURSE FOR MACHINE PROCESSING OF
DATA.
COOPERATOR — An organization or agency which actively participates in the California
Cooperative Snow Survey Program by making snow surveys or contributing time, services,
money, etc., for furtherance of the program's activities (see list on page vm). In
addition, there are many agencies which make data available to the Snow Survey Program.
These agencies are not listed as cooperators since their data are not collected
specifically for the program.
CORE — Snow trapped and withdrawn from the snowpack by a snow sampler tube. The length
of the core is measured and its weight recorded before being emptied from the tube.
DENSITY -- The ratio of water content to depth of snow expressed in percent. The density
FOR A given snow COURSE IS OBTAINED BY DIVIDING THE MEAN WATER CONTENT BY THE MEAN DEPTH
FOR THE ENTIRE COURSE, NOT BY COMPUTING AND AVERAGING DENSITIES FOR EACH SAMPLE POINT.
DEPTH — The depth of snow, usually measured in inches. The depth recorded for a given
SNOW course for a particular measurement is the mean depth for all sample points on
THAT course.
ELEVATION -- The average elevation of the snow course, in feet above mean sea level, as
DETERMINED FROM U. S. GEOLOGICAL SuRVEY QUADRANGLES. ELEVATIONS IN THIS SUMMARY ARE
TO THE NEAREST 5O FEET.
HYDROGRAPHIC AREA — A geographical area determined by drainage boundaries. California has
BEEN divided INTO SEVEN MAJOR HYDROGRAPHIC AREAS. ThEY ARE:
5. Central Valley area
6. Lahontan area
7. Colorado Desert area
1. North Coastal area
2. San Francisco Bay area
3. Central Coastal area
k. South Coastal area
MEAN -- The average obtained by dividing the total of several quantities by their number.
SAMPLE POINT -- A point located upon a snow course at which determinations of depth and
WATER content ARE MADE. SAMPLE POINTS ARE USUALLY SPACED FROM 50 TO 100 FEET APART
WITH AN AVERAGE OF 10 POINTS PER SNOW COURSE.
SNOW COURSE — An established line along which sample points are located for the purpose of
MEASURING SNOWPACK. An IDEAL SNOW COURSE IS LOCATED IN A MOUNTAIN MEADOW, FREE FROM
EXTREME DRIFT, MELT, WIND, AND PONDING. IX MAY CONSIST OF EITHER ONE OR TWO LEGS WITH
A TOTAL OF ABOUT 10 SAMPLE POINTS SPACED AT 100-FOOT INTERVALS. ThE END POINTS OF EACH
leg are marked with permanent signs on trees or poles, so that surveyors may measure
along the same line each year. as stated, the description is of an ideal snow course,
and in practice, many variations exist.
Measurements made at a snow course provide an index to snow cover in the basin, and
SHOULD not be TAKEN AS AN ACCURATE MEASURE OF WATER CONTENT THROUGHOUT A LARGE AREA
without CAREFUL STUDY OF BOTH THE COURSE AND THE AREA.
SNOW SURVEY — The process Of measuring snow depth and water content along a snow course.
Data obtained by snow surveys are of great value in preparing forecasts of runoff during
the spring snowmelt season.
UNIMPAIRED, nJLL NATURAL, OR UNREGULATED STREAMFLOW (Runoff) — The flow of a stream as it
would be if unaltered by upstream diversion, storage, import, or change in consumptive
USE CAUSED by UPSTREAM DEVELOPMENT. NATURAL RUNOFF IS RECONSTRUCTED FROM MEASURED RUNOFF
BY ALLOWING FOR THE QUANTITATIVE EFFECT OF ALTERATIONS IN STREAMFLOW ABOVE THE POINT WHERE
THE FLOW IS MEASURED OR COMPUTED.
WATER CONTENT (Often called Water Equivalent) — The amount of water, expressed in inches of
DEPTH, WHICH WOULD RESULT FROM MELTING SNOW IN PLACE. FoR EXAMPLE, A SNOWPACK 100 INCHES
DEEP MIGHT HAVE A WATER CONTENT OF 35 INCHES. WATER CONTENT IS THE INFORMATION UPON
WHICH SNOWMELT-RUNOFF RELATIONSHIPS ARE BASED. MEASUREMENT IS BY MEANS OF A MT. ROSE
TYPE SAMPLING TUBE IN WHICH A SNOW CORE IS WEIGHED TO DETERMINE WATER CONTENT. ThE SNOW
COURSE WATER CONTENT IS THE MEAN WATER CONTENT OF ALL SAMPLE POINTS ALONG THE COURSE.
