Definition of Status QuoDefinition of Status Quo
The “Status Quo” describes existing or
anticipated conditions of a water resources
system if policies, system
configurations, regulations,
and management strategies
remain unchanged.
Defining the Status Quo RequiresDefining the Status Quo Requires
A shared understanding of the physical, technical, regulatory, management, and policy attributes of the system
A statement of important problems facing the region
Identification of uncertainties and discrepancies in information and policies
A common vocabulary for future discussion
When the Status Quo is DefinedWhen the Status Quo is Defined
Managers and stakeholders develop a shared
understanding of system attributes and
management concerns.
Confirm the appropriateness of planning objectives
Identify constraints to planning alternatives
Establish a baseline for comparison with proposed alternatives
Once the status quo is established it is used to
Status Quo for Tactical and Strategic PlansStatus Quo for
Tactical and Strategic Plans
Tactical Plans define the status quo in terms of existing conditions
Strategic Plans use long-term forecasts to describe future conditions
Activities in Defining the Status QuoActivities in Defining the Status Quo
Perform a facility inventory, a resource inventory, a legal, policy, economics, management and demand inventory
Resolve conflicting information and data gaps
Develop a Shared Vision Model to develop an integrated expression of your system’s performance
Examine system performance under different hydrologic scenarios

Choice of Hydrological Data in Status Quo Analysis
Choice of Hydrological Data in Status Quo Analysis
Evaluation of the status quo requires understanding of the average performance of a system as well as its performance under extreme conditions
Good hydrologic data is essential for these assessments
Options for Short Hydrologic Records
Options for Short Hydrologic Records
If hydrologic records are short
Accept historic data set and acknowledge uncertainty
Use data set from a region with similar characteristics
Develop “synthetic” data
Pros and Cons of Design Droughts and Floods
Pros and Cons of Design Droughts and Floods
Use of a Design Drought
Pros
Represents a sequence of events that has actually occurred
Impacts may be tangible to managers and stakeholders
Cons
Will not reoccur in the future
A more severe drought may be possible
May provide region with a false sense of security
Does not provide information on overall system performance
Pros and Cons of Design Droughts and Floods
Pros and Cons of Design Droughts and Floods
SummarySummary
Managers and stakeholders must work to establish a collectively endorsed vision of the status quo.
The status quo acts as a baseline for the comparison of alternatives.
Shared vision models are used to assess cumulative impacts of the status quo.
Hydrologic data sets should be carefully chosen when defining the status quo.
