The water-quality reconnaissance in the Dirty Devil River basin, covered an area of about 4,300 square miles (11,100 square kilometers). were obtained by the U.S. Geological Survey one or more times at 104 during the period July 1975 to September 1976; and during visits to 34 sites during the same period, the streams were dry.
The automatic suspended-sediment sampler was originally designed to obtain a suspended-sediment sample from a single point in a stream or reservoir during a rise in stage. The sampler was intended to be used during periods when manually-operated standard samplers could not be used. If the sampling site is remote from the field office or is inaccessible during storm periods or if no notification can be obtained concerning a stream rise, an adequate sampling program may be difficult to maintain. Having full knowledge of the many limitations and inadequacies of this automatic sampler, personnel of several of the Quality of Water Branch offices believe that, for many types of sediment transport and for specific sampling sites, samples obtained with the automatic sampler are preferable to a complete lack of samples.
