Update

Update 2017:The SJBEP participated of the (2015) Feasibility Report & Environmental Impact Statement for the Caño Martín Peña Ecosystem (FR/EIS) Restoration Project. The SJBE Program was in agreement with both the dredging and the filling actions proposed, and provided recommendations to safeguard the water quality and protect the natural habitat of the area during the project’s implementation.

Regarding the dredge material disposal in Contained Aquatic Disposal (CAD) pits, the SJBE Program suggest a proper capping of the fill to avoid any further degradation to water quality of the San Jose Lagoon and the SJBE. The SJBEP and its Scientific and Technical Advisory Committee (STAC) are more than interested in providing support and collaboration during the implementation of the proposed project.

Update March 2012: There has been controversy between the fishermen who use the ecosystem about the surrounding the toxicity of the sediments and the material that is going to be dredged out of the Caño Martín Peña which in turn is the material that the SJBE Management Plan recommends to be used to populate the artificial depressions that are located in the zone. There is an existing debate right now if it is actually appropriate to use a toxic sediment and trash from 50 years on soil to fill the depressions at the bottom of the Laguna San Jose, Canal Suarez and Torrecillas. This is a topic currently under discussion.

Update January 2010:  The action can not be completed until the dredging of the Caño Martin Pena is completed, however the SJBEP has been in conversation with the fishermen of the area opposed to artificially fill these depressions.  
Fishermen of Shad fish understand that this fish goes to the depth offered by the depression to spawn, although they have been told that the water is anoxic at the bottom of these holes, so there is no life there.

Previous update:  In addition to serving as a technical advisor throughout this process, the SJBEP participates in educational activities, organizes interagency meetings, and is the most significant tool used by government agencies during the decision-making process.


Strategies  
WS-6.1 Conduct a bathymetric survey of the present extension and depth of the depressions to determine the volume of fill material needed.
WS-6.2 Identify source(s) for suitable fill material. Perform sampling and laboratory analysis of fill material to assess contaminant concentrations and toxicity.
WS-6.3 Initiate filling of dredged depressions up to the historical average depth once the necessary permits have been obtained.
