A simple sampler activating device that resulted in automated sample procurement and simultaneous hydrograph time-stage notation was developed as part of a project to assess the impact of rural nonpoint sources on an average basis. The total instrumentation for continuous gaging and automated smapling was battery operated because sampling sites were in rural areas.
