This final grant report is subdivided into two major sections. The first section describes the distribution and abundance of submerged aquatic vegetation (SAV) in the lower Bay. Baseline information for SAV was collected in 1978 and supplemented with additional information from 1979. Subsequently, in 1980 and 1981, overflights were conducted of all polyhaline and mesohaline areas mapped for SAV in 1978 and photographs were taken from which aerial coverage of the vegetation was measured. The data from 1978 through 1981 were analyzed for short term changes in SAV distribution and abundance.
