In-stream denitrification rates were calculated using a simultaneous nitrogen and dissolved oxygen mass balancing technique. Anaerobic, laboratory, incubation of stream bottom samples resulted in potential denitrification rates that were very similar to model projections. Relatively high rates (28. mg minus N/m**2/hr) were observed for stream bottom samples that were dominated by rocks and mostly devoid of organic material. (Author abstract. )
