Abstract
Three contrasting segments of a stream, exhibiting varying levels of production, were monitored for water quality, oxygen-derived primary productivity and the yield and growth rate of indigenous aquatic plant biomass. Average daily primary productivity rates observed for the respective segments included: 3.9 g O2/sq m/day for a low in-stream phosphorus (22 micrograms total P/L), periphyton-dominated community; 5.5 g O2/sq m/day for a low in-stream phosphorus (17 micrograms total P/L) mixed periphyton-macrophyte community; 18.3 g O2/sq m/day for an enriched phosphorus (1,340 micrograms total P/L) macrophyte-dominated community. Additional data are presented for sediment and interstitial sediment water nutrients and macrophyte biomass variations over a growing season. Specific photosynthetic rates estimated for the macrophyte population ranged from 0.005/day to 0.244/day for the low phosphorus environment to from 0.036/day to 0.456/day for the phosphorus-impacted segment. The need to accomodate natural and wastewater-derived in-stream aquatic plant productivity in wasteload allocation analysis is discussed.
