Datasets
These datasets are either Excel 5.0 spreadsheets or
tab-delimited ASCII textfiles. The Excel files require Excel 5.0 or
later; the textfiles can be read by nearly any program. Before you
use any datafiles, look at the column headers to see what data
is in each column. Some programs or macros may require that the
column headers be removed before importing the file.
- Eureka Rainfall Data
-
- The Eureka raingage is operated by the National Weather
Service; its record begins in 1887. From 1 December 1886 through
31 December 1910, the gage was located at the Buhne Building at
2nd and G Streets. On January 1, 1911, it was moved to the US Post
Office & Courthouse at 5th and H Streets in downtown Eureka.
On October 16, 1994, the gage was relocated to the new National
Weather Service office on Woodley Island, about 0.5 mi north of
the previous location.

- Upper Mattole Rainfall Data
-
- The Upper Mattole raingage operated from 1888 through 1986. It
was located in the Mattole R valley about halfway between Petrolia
and Honeydew at an elevation of 255 ft. This is one of the wettest
areas in Humboldt Co.

County Rainfall Data
-
- This is a table of the 1) mean annual precipitation, 2) period
of record, 3) elevation, 4) location, and 5) distance from the
coast at 57 selected Humboldt County and near-by gages. It was
compiled from the California State Department of Water Resources
Publication "California Rainfall Summary 1849-1980" and
measurements from topographic maps. A map
of the stations is available.

- Jacoby Creek Hydrologic
Data
-
- Jacoby Creek is a small (< 20 sq mi) forested drainage
basin lying immediately south of Arcata, CA. The USGS operated a
gaging station in the upper part of the basin (DA = 6.07 sq mi)
from 1955 to 1964, and a crest-stage gage at the site from
1965-1974.

-
- Dr. Tom Lisle of the Forest Service Redwood Sciences Lab
established a gaging station on Jacoby Cr immediately upstream of
the covered bridge on Brookwood Dr. (DA= 13.7 sq mi) in the late
1970's. It operated on an event basis into the mid 1980's. Tom has
been kind enough to share some of his data with us. HSU hydrology
and fluvial processes classes have made occasional additional
gaging measurements at this site.
