Publication 
Water Resources Data 
Publication Interval: Yearly 
Location: The 50 states 
Period of Coverage: Varies 
Contents: For the water year and state or states of interest, this publica- 
tion consists of records of stage, discharge, and water quality of streams; 
stage, contents, and water quality of lakes and reservoirs; and water levels 
in wells. 
The stream discharge data include location of the measuring site, the 
drainage area in square miles, the period of record, information on the mea- 
suring gages, the discharge in cubic feet for each day of the year, and some 
mean and extreme discharge data. 
The lake level data include location, drainage area, period of record, 
gage information, mean and extreme data, and the lake level contents and 
change in contents for each month. 
The water quality stations report stream flow, weather conditions, con- 
ductance, pH, water temperature, turbidity, and dissolved mineral contents. 
The date and time of observations are included with the data. 
Sediment data include concentration of particles, load carried in tons 
per day, water temperature, and information on the size of the particles 
(percent finer than a given sieve size). These data can be useful to sediment 
budget analysis for littoral transport study. That is why reports are grouped 
in this part, "Beach Erosion and Littoral Transport." 
Available From: These reports carry an identification number 
consisting of the two-letter state abbreviation, 
the last two digits of the water year, and the 
volume number. For example, MT-/8-1 is the 
first volume of the 1978 Montana Water Resources 
Data publication. 
These reports are not in the same format as 
later reports but consist of the same general 
contents. All of these water data reports can 
be purchased from:
