Aquatic Resource Monitoring - Initial Monitoring & Design Approaches for
Great Rivers
|
|
Issue: Comprehensive, large-scale monitoring information on Great River
Ecosystems is vital and often missing and therefore assessments of aquatic
resources associated with the Great Rivers are limited.

Resource Definition:
-
Draft Criteria: Catchments>10K sq mi and Discharge >25K cfs
-
Draft Map of 11 Great Rivers in lower 48
-
A set of draft domains have been constructed that include three or four
geomorphic-based reporting units in each river system.
Initial Questions:
-
Emphasis on status and trends in ecological condition
-
Role and information provided by Design-based approaches
-
Role and information provided by Model-based approaches
Role and Assistance of the Design Team:
-
Aid in refinement of information for addressing the steps in design process
(Resource Characteristics, Monitoring Objectives, Institutional Constraints,
Sample Frame, Design Requirements and Survey Design)
-
Participation in monitoring design and analysis pilot(s)
-
Potential integration of existing monitoring information and programs
Preliminary designs have been completed:
-
Ohio River (Pittsburgh, PA to the Mississippi confluence)
-
Upper Missouri River (Three Forks, MT to the Mississippi confluence)
-
Upper Mississippi River (Lake Itasca, MN to the Missouri River confluence)
-
