LOWER MISSISSIPPI RIVER AQUATIC RESOURCE MANAGEMENT PLAN GOALS & OBJECTIVES |
|
B. WATER QUALITY
- Improve water quality in the Lower
Mississippi River by implementing the Clean Water Act . Objective B.1 Determine
short- and long-term water quality trends in the Lower Mississippi River
system. Strategy B.1.1 Identify
monitoring sites and areas of concern for water quality (e.g., pH, sediment
concentration, dissolved oxygen, nutrients, heavy metals, pesticides). Strategy B.1.2 Increase
the number of water quality monitoring sites in under-represented river reaches
and major tributaries. Strategy B.1.3 Support
development of uniform sampling/data collection strategies that identify
critical baseline water quality parameters (pH, dissolved oxygen, suspended
sediments, etc.) to be collected on a regional basis. Strategy B.1.4 Identify
state and federal agencies that have or are collecting water quality data in
the Lower Mississippi River basin. Strategy B.1.5 Work
with state and federal agencies to review and summarize water quality data. Strategy B.1.6 Integrate
historical and present water quality data sets into GIS databases and analyze
the changes that have occurred. Objective B.2 Coordinate development of a Water Quality Master Plan. Strategy B.2.1 Identify
and catalog major sources of pollution and contaminants. Strategy B.2.2 Develop
and implement new procedures and support existing Best Management Practices (BMPs) to reduce pollution and contaminant influx into the Lower Mississippi
River watershed. Strategy B.2.3 Assist
state and federal agencies in reducing pollution influx into the watershed. Strategy B.2.4 Support
the Clean Water Act and other legislation that would reduce pollution and
improve water quality. Strategy B.2.5 Reduce
contaminants in fish to acceptable levels (see Objective B.4). Objective B.3 Improve
water quality and reduce annual flood damage by restoring floodplain hydrology. Strategy B.3.1 Determine
water filtration capacities (e.g., location, areal extent relative to river
stage) of existing floodplain habitats in the Lower Mississippi River system. Strategy B.3.2 Increase
the connectivity between the Lower Mississippi River and its floodplain (See
Objective A.3). Strategy B.3.3 Identify
potential sites in the floodplain of the Lower Mississippi River system that
could be restored as wetland and bottomland hardwood habitats. Strategy B.3.4 Promote
projects that would increase the area of naturally functioning floodplains. Strategy B.3.5 Support
projects and legislation that increase the connectively between floodplain and
the Lower Mississippi River. Objective B.4 Cooperate with
State Department’s of Health to monitor and reduce contaminant levels in fish. Strategy B.4.1 Encourage
each state natural resource agency to periodically collect fish tissue samples
for contaminant analysis in accordance with Department of Health guidelines. Strategy B.4.2 Ensure
that standardized fish contamination advisory levels for all chemical compounds
of concern are used.
Strategy B.4.3 Survey
Lower Mississippi River Conservation Committee agencies and develop a detailed
summary of fish species and causative agents involved in fish consumption
advisories in the Lower Mississippi River system. Strategy B.4.4 Cooperate
with each state’s Department of Health to issue fish consumption or other
river-related health advisories. Strategy B.4.5 Cooperate
with state Departments of Health to issue news releases of contamination levels
in fish and fish consumption or other river-related health advisories. Objective B.5 Develop
a spill contingency plan for the Lower Mississippi River system. Strategy B.5.1 Determine
the agencies and procedures currently involved in spill contingency planning in Lower Mississippi River
Conservation Committee member states, and work cooperatively with them to
develop a coordinated plan for the Lower Mississippi River system. Strategy B.5.2 Develop
an “early-warning system” for the Lower Mississippi River system based on
time-in-travel studies that will determine the time required for contaminants
to pass through the Lower Mississippi River system, as well as dilution, elution
and dissipation rates as contaminants pass downstream. Objective B.6 Work
with the Corps of Engineers to improve water quality in the Lower Mississippi
River system. Strategy B.6.1 Identify
and quantify contaminated sediments in frequently dredged reaches of the main
channel. Strategy B.6.2 In areas
where contaminated sediments exist, determine amounts of contaminants that will
be resuspended in the water column due to dredging activities. Strategy B.6.3 Determine
potential impacts of resuspended contaminants on aquatic biota. Strategy B.6.4 Implement
channel maintenance measures that reduce dredging activities and resuspension
of contaminated sediments. Strategy B.6.5 Implement wetland habitat construction/restoration projects using dredged material, rather than reintroducing contaminated dredged material into the main channel.
