Abstract
Paclo Marsh, located in Eureka, is a 39 acre wetland containing salt, brackish, and freshwater marshes and riparian areas. Historically, the site was a mosaic of tidal marsh and sandy grassland, but most of the marsh was diked off from the bay over 100 years ago, and it received only muted tidal action thereafter. Insufficient tidal flushing and prolonged ponding caused the development of anaerobic conditions and the degradation of biological resources.
In fall 1991, Phase 1 of the Paclo Marsh Enhancement Project was implemented. In an effort to improve tidal flushing in the salt marsh, an inverted siphon was installed and slough channels were excavated. A baseline report was prepared documenting pre-enhancement monitoring conducted between the fall of 1991 and winter of 1993-1994. An interim report documented post-enhancement monitoring conducted between the fall of 1991 and the winter of 1993-1994. This final report includes a summary of previous work and the results of monitoring through 1995.
