An Ocean Blueprint for the 21st CenturyFinal Report of the U.S. Commission on Ocean Policy
The US Ocean Action PlanThe Administration’s Response
Both called for the creation of a National Water Quality Monitoring Network
Origins of the ProjectOrigins of the Project
33
Three Ocean Commission Recommendations:
1. Develop network that coordinates and expands
existing efforts
2. The network should include coverage in both the coastal and upland areas that affect them, and be linked to the Integrated Ocean Observing System
3. Network must have clear goals, specify core variables, and an appropriate sampling framework, and be periodically reviewed and updated.

• Design the network using criteria derived from:– Specified goals and objectives– Management questions
• Compare design with existing monitoring efforts
• Then:– Include– Improve– Define as external to the Network
Approach to the DesignApproach to the Design
66
• Integrate, coordinate, and as necessary enhance water quality monitoring efforts needed to make informed management decisions for sustainable use of aquatic resources.
• Communicate the availability of quality assured data, and disseminate information products relevant to national, regional and local needs.
Goals of the National Water Goals of the National Water Quality Monitoring Network Quality Monitoring Network
77
1. Define status and trends of key water quality parameters and conditions on a nationwide basis.
2. Provide data relevant to determining whether goals, standards, and resource management objectives are being met, thus contributing to sustainable and beneficial use of coastal and inland water resources.
3. Provide data to identify and rank existing and emerging problems to help target more intensive monitoring, preventive actions, or remediation.
Objectives of the National Water Objectives of the National Water Quality Monitoring NetworkQuality Monitoring Network

4. Provide data to support and define coastal oceanographic and hydrologic research, including influences of freshwater inflows.
5. Provide quality-assured data for use in the preparation of interpretive reports and educational materials.

What the Network Will What the Network Will ProvideProvideA framework A framework • That links the upland to the coasts and ocean• Provides national coverage• That can support local needs:
– Finer temporal or geographic scale– Additional indicators
• That has data standards• That has provisions for data management
and access

What the Network Will NOT What the Network Will NOT CoverCover
• Provide data on all water resources– Small rivers– Lakes and reservoirs– Local aquifers
• Replace State Clean Water Act use attainment monitoring– 305b and 303d
