Desired water levels were attained in 1974 which resulted in the inundation of several thousand acres of old marsh bottom, hayland, pastures and formerly cultivated fields. Management of the marsh since that time has been under the direction of a loosely knit advisory committee. Recently the co-operating agencies have been concerned that although the marsh has considerable potential, that potential is far from realized. Major botulism outbreaks in 1980 and 1981 focused attention on the marsh and its apparent water supply problem. That, coupled with declining macrophyte communities despite low water levels, prompted a re-evaluation of the development and management scheme. Toward that end,D.U. has undertaken major biological and engineering investigations during 1981 and 1982. This preliminary report outlines the results of our investigations and suggests remedial acti
