The biomass and distribution of submersed macrophytes in the Currituck Sound, N.C. [North Carolina] were determined in July, 1978 and compared with that of Aug. 1973. Eurasian watermilfoil (Myriophyllum spicatum L.) was dominant in 1973 and bushy pondweed (Najas guadalupensis (Spreng.) Mangus) was a strong subdominant. Plant biomass in 1978 was 42% of that of 1973. Eurasian watermilfoil biomass was reduced by 54% in 1978 and bushy pondweed occurred in only trace amounts. Biomass of sago pondweed (Potamogeton pectinatus L.) in 1978 was greater than that measured in 1973. The changes in biomass and, to some extent, distribution are attributed primarily to increased turbidity and turbulence resulting from unusual weather during the early growing season of 1978. This is supported by seasonal studies of an Eurasian watermilfoil community in Coinjock Bay which is contiguous with Currituck Sound.
