TAXONOMIC COVERAGE:
Organisms studied

Methods:	General: A total of 500mL of a concentrated NaBr solution was injected to a hyporheic well at the upstream end of a riffle over 10 minutes. Thirty mL samples were collected from downstream hyporheic wells and the conductivity of those samples were determined immediately. Well Construction/Installation: Hyporheic samplers consisted of a 1/8 inch O.D. stainless steel (S.S.) tube housed in a 3/4 inch CPVC pipe. At the lower end of the CPVC a rubber stopper was inserted with the S.S tube protruding ten centimeters. A coupler was then used to attach a length of well screen to protect the S.S. tube. Samplers were inserted into the stream bed by forcing a pry bar into the stream bed to a depth of the maximum depth allowed, typically 30-60 centimeters. The sampler was then worked down into the hole and the pry bar removed, allowing the hole to cave in onto the sampler. The length of the sampler, still above the substrate, was measured and subtracted from the total length to find the depth of the sampler in the substrate. Samplers were allowed to settle before any testing occurred.
