Abstract. A stream water sampler was designed and tested to sample water from a streamat a rate proportional to the streamflow rate. A composite of samples taken in this manneris an estimate of the mean concentration of constituents carried by the stream while thesample was collected. The instrument is suitable for estimates of transport of suspendedor dissolved constituents in small streams. The sampler can be built for under $1000.
