A significant contributor to the development of improved methods in
estimating irrigation water requirements, Marvin E. Jensen has had a diverse
career in civil engineering. He worked as a consultant and a university
employee, and served a government agency. Not only was he instrumental in
analyzing water flow and apportionment for agriculture projects, but Jensen
developed real-time analysis of water requirements for irrigation, which
continues to be used in irrigation water scheduling throughout the United
States.
Born in Minnesota in 1926, Jensen attended North Dakota State
University where he specialized in soil and water and received his bachelor's
degree in 1951. He received his master's degree from the same institution in
Agriculture Engineering in 1952. He received his Ph.D. in Civil Engineering
from Colorado State University in 1965.
Working with water management in western states, he served the United
States Department of Agriculture (USDA) from 1955 to 1987. During his time with
the USDA, Jensen worked as Agricultural Engineer at Bushland, Texas and the
head of the Irrigation, Drainage and Water Storage Facilities Section in Fort
Collins, Colorado. He also served as Investigations Leader in Water Management
for the Soil and Water Conservation Research Division in Fort Collins and
Kimberly, Idaho. From 1968 to 1978, Jensen was Director of the Snake River
Conservation Research Center in Kimberly, Idaho. From 1979 to 1987, Jensen
planned, implemented, and reviewed water management research throughout the
United States as the National Program Leader for Water Management Research with
the USDA. Following his work with the USDA, Jensen served as Director of the
Colorado Institute for Irrigation Management at Colorado State University.
Additionally, from 1989 to 2004, Jensen served as a consultant to the Wyoming
Attorney General.
Jensen's career included international work in Sri Lanka, Egypt,
Romania, China, Pakistan and Bulgaria. He served as a long-term member of the
American Society of Civil Engineers' Irrigation and Drainage Committee and as
World President of the International Commission on Irrigation and Drainage from
1984 to 1987. For the American Society of Agricultural Engineers, Jensen was
the Soil and Water Director from 1980 to 1982 and the Technical Vice President
from 1983 to 1986. He has also been a member of the American Society of
Agronomy since 1965.
Throughout his career, Jensen received numerous awards for his service
and contributions to science, agriculture, and water resources. He was inducted
into the Agricultural Research Service (ARS)-USDA Science Hall of Fame in 2000,
elected honorary member (now called distinguished member) of the American
Society of Civil Engineers (ASCE) in 1989, and presented with the ASCE's Royce
J. Tipton Award in 1982 and the USDA Distinguished Service Award and the
Irrigation Association Man of the Year Award in 1983. In 2007, Jensen was
awarded the Environment and Water Resources Institute's Lifetime Achievement
Award.
The Papers of Marvin E. Jensen consists of documents dated 1957 to
2004, with the bulk of the unpublished material falling from 1993 to 2002. This
collection documents two special projects Jensen worked on to evaluate water
distribution and usage along the lower Colorado River; one on the Lower
Colorado River Accounting System (LCRAS) and the other on water use by the
Imperial Irrigation District (IID). The collection includes materials used and
created by Jensen to review the LCRAS, recommend changes, and develop crop,
water surface, and vegetative coefficients for the system and for the
estimation of the Colorado water consumption from Hoover Dam to Morelos Dam on
the U.S.-Mexico border. The collection also includes materials used and created
by Jensen for his evaluation of Colorado River water usage by the IID for the
United States Bureau of Reclamation. Documents include memoranda,
correspondence, maps, data, photographs, handwritten notes, references, drafts,
and final reports.
A detailed inventory list provided by Dr. Jensen was used as the basis
for arrangement.
Papers of Marvin E. Jensen, Water Resources Archive, Colorado State
University.
The Papers of Marvin E. Jensen was donated to the Water Resources
Archive by Marvin E. Jensen in August 2006. An additional donation was received
in April 2008.
The Papers of Marvin E. Jensen arrived in ten boxes. Most material was
housed in three-ring binders with spine labels and multiple dividers. Other
material was housed in folders. Binders and folders were in chronological order
or were arranged to be. Materials within folders are in reverse chronological
order.
All materials were re-housed in acid-free folders and boxes. Paper
clips and staples were replaced with plastic clips. Self-stick notes were
copied and then removed. The copy was placed in front of the original document.
Acid-free paper was placed next to documents that have tape. Transparency
overheads were interleaved with acid-free paper. Photographs were removed from
a photo album and envelopes and placed in archival photograph sleeves and in
acid-free folders. Negatives were removed from original envelopes and placed in
an archival envelope. Duplicate copies of data charts were removed.
The United States Bureau of Reclamation's web page about Lower
Colorado River Water Accounting contains links to yearly LCRAS reports, some of
which were written by Jensen.

Series II: Imperial Irrigation District Water Use Study, 1957-2002 (5 linear feet)
|
|
The Imperial Irrigation District (IID), located near the
U.S.-Mexico border in California, is one of the largest irrigation districts in
the country. From 1993 to 2002, Jensen evaluated the Imperial Irrigation
District's water usage for the United States Bureau of Reclamation (USBR). In
his first report for the USBR in 1995, Jensen concluded that the IID was using
an unreasonable amount of water. This series consists of the handwritten notes,
data, correspondence, references, and drafts used by Jensen for evaluating the
IID, defending his report after the IID contested his results, responding to
criticisms, and collaborating with Ivan A. Walter on additional assessments of
the IID for the USBR. The series is arranged into three subseries in
chronological order according to the reports that Jensen worked on. The
materials are divided: Water Use Assessment of the Imperial Irrigation
District, Assessment of 1987-1996 Water Use by the Imperial Irrigation District
Using Water Balance and Cropping Data, and Assessment of 1997-2001 Water Use by
the Imperial Irrigation District. Each subseries is named after the title of
the final report for that particular phase of evaluation of the IID for the
USBR. |
|
|
The subseries are arranged in rough chronological order according
to the original order used by Dr. Jensen. Most material was previously housed
in three-ring binders. Folders are labeled with the original binder titles.
These and the internal divider titles are listed in the inventory. For clarity,
some binder and folder titles were taken from an inventory list provided by Dr.
Jensen, not the actual binder spine or divider label. |
|
|
Subseries A:
Water Use Assessment of the Imperial Irrigation
District, 1993-1997
|
|
|
This subseries consists of materials created and used by Dr.
Jensen in preparing his first evaluation of Colorado River water usage by the
IID. It also includes material related to the response of the IID regarding the
Jensen report and the USBR response to the comments made about the report by
the IID. This subseries includes correspondence, data, handwritten notes,
references, and drafts. |
|
Subseries B:
Assessment of 1987-1996 Water Use by the Imperial
Irrigation District Using Water Balance and Cropping Data, 1957-2000
|
|
|
The second report evaluating the IID's use of Colorado River
water for the USBR was written in collaboration with Ivan A. Walter, a water
resources engineer. This subseries consists of materials created and used by
Jensen and Walter in evaluating the IID. It includes information from meetings
held between the IID and the USBR, and the Coachella Valley Water District and
the USBR. An IID response to the second report, published by a Work Study Team
in 1998 is also included. This subseries includes correspondence, data,
handwritten notes, references, drafts, news clippings, and photographs. |
|
Subseries C:
Assessment of 1997-2001 Water Use by the Imperial
Irrigation District, 2002
|
|
|
The final report published by Dr. Jensen, also in collaboration
with Ivan A. Walter, was published in 2002. This subseries includes materials
they created and used to update the previous two reports and incorporate new
information and procedures in their evaluation of IID's water usage. This
subseries includes correspondence, data, handwritten notes, and news
clippings. |
