INTRODUCTION

The month of December 1996 and the first week of January 1997 brought

tremendous amounts of rain and snow to parts of the states of Washington,

Oregon, Idaho, California, Nevada, and Montana. In particular, the period

of December 26 through January 3 was especially severe with over 20 inches

of rain in some locations. This, along with unusually warm temperatures

which produced tremendous snowmelt, resulted in record flooding in some

areas. Emergency management officials in these states indicate that as

many as a half a million people were forced to evacuate at one time or

another during December through early January.

DISCUSSION

The valleys surrounding the Sierra Nevada were especially hard hit, as the

Truckee River reached its highest level on record. Lake Tahoe reached its

highest level since 1917. The Army Corps of Engineers released a

preliminary estimate ranking this flooding as a 50-year event (a 2% chance

of occurrence in any given year) for the Sacramento River.

As of January 20, in California, 43 of its 58 counties had been declared

disaster areas. US-50 across the Sierra was Acut@ in five places by

mudslides and flooding. Sacramento was spared the worst of the flooding by

a system of levees, although many nearby towns were not so fortunate.

Numerous levee breaches and breaks occurred across the state. 

Approximately 16,000 residences were damaged or destroyed. State officials

now estimate at least $1.6 billion in damages to private and public

property, although estimates are still rising as the damage surveys

continue. 

In Nevada, Reno alone estimates approximately $170 million in damages, with

the state total possibly reaching $500 million. Damage to casinos and

businesses in the Reno area was quite extensive.

In Washington, $125 million is the estimate for insured losses, but the

addition of uninsured losses will add greatly to the total. Mudslides were

a severe problem, especially in the Seattle area. 

In Oregon, areas along the Rogue River in the south and in the vicinity of

the Tualatin River near Portland were among the most-affected areas of the

state. Damage estimates were not yet available, but appeared to be less

extensive than surrounding states.

In Idaho, about 400 miles of roads were closed, and over 10,000 people were

isolated at one time by flooding and mudslides. Approximately one-third of

the state=s counties were declared disaster areas. Damage estimates were

not available at the time of this report.

Also as of January 20, the overall death toll was 36, with the following

state totals:

California--8

Oregon--3
3

Washington--19

Idaho--5

Nevada--1

This is the third consecutive year that the west coast has been impacted by

severe flooding. California was severely affected in January and March of

1995, while the Pacific Northwest was affected in February 1996 and again

in November 1996. During 1995, El Nino conditions were present in the

equatorial region of the eastern Pacific with warmer than normal sea

surface temperatures. During 1996 however, there was no evidence to

suggest El Nino conditions in the Pacific. Therefore, some of the same

areas of the west coast, especially central-northern California, were

affected by severe flooding both in 1995 (El Nino period) and in this

latest event (non-El Nino period). 

Following is a state-by-state summary of river flooding as reported by the

U.S. Geological Survey:

California--Significant flooding occurred on 15 rivers, with historical

peaks approached or exceeded on three rivers:

* The Cosumnes River at Michigan Bar exceeded the previous record level by

0.7 feet on January 2 and was still rising at that time. Records began in

1907.

* The South Fork American River near Camino, with a flow volume of

approximately 70,000 cubic feet per second, exceeded the previous record by

20,200 cubic feet per second. Records began in 1922.

* The Napa River near St. Helena crested January 2 just below the previous

record peak set in 1986.

Idaho--Flow of the Payette River near Horseshoe Bend peaked at 24,500 cubic

feet per second, approximately a 50-year recurrence flow rate. The Snake

River below Hells Canyon Dam reached 102,000 cubic feet per second, a new

record.

Nevada--Flooding in northwest Nevada approached or exceeded records for the

Truckee, Carson, and Walker Rivers and their tributaries. This event was

similar in severity to the historical event of 1955.

Oregon--Flooding was widespread, although no new records have yet been

indicated.

Washington--Significant flooding on the following rivers:

* Hangman Creek at Spokane crested on January 1 at a record high discharge

of 25,800 cubic feet per second and peak stage of 14.6 feet. This is 5200

cubic feet per second above the record set in 1963.

* The Palouse River at Hooper in Whitman County and the Klickitat River

near Pitt in Klickitat County reached discharge rates with recurrence

intervals of 10 years.
4

* The White Salmon River near Underwood in Skamania County, the

Skookumchuck River in Lewis and Thurston Counties, and the Chehalis River

near Grand Mound and at Porter reached discharge rates with recurrence

intervals of 10 years.

FIGURES AND TABLES

Figures 1 through 4 are color-contour analyses of December 1996

precipitation for the western U.S. California is shown separately due to

the availability of many additional stations from the California Department

of Water Resources. Figures 5 through 8 are data plots for December for

the same areas. Figure 9 is an analysis for December 20 through January 3,

the period of heaviest rainfall which produced the severe flooding. Figure

10 is a color-enhanced infrared satellite image for December 31. Finally,

Tables 1-2 provide all of the precipitation amounts used in producing

Figures 1-9. These values are preliminary and subject to change.
