CLAM – Coastal Lake Assessment and Management tool
Healthy Rivers Commission 2002 report
Sustainability Assessment tool
Catchment capability
Effect of remedial actions
Combinations of development and remedial actions (i.e. management plan)
iCAM contracted by DNR to prepare CLAMs as SA tools
CLAM – Coastal Lake Assessment and Management tool
Catchment management decision support tool – modelling
Land use
Export rates
Lake processes
Mgt actions
Lake specifics
etc.
Maximise effectiveness of limited funding
CLAM interface
Set combination developments and interventions
… probability distributions
Using CLAMs – 2 main points
Where do CLAMs fit in the NR manager’s toolbox?
How can CLAMs help ensure
sustainability of coastal lakes
AND
sustainability of coastal lakeplanning processes and documents?
CLAMs among the NR manager’s other tools
General management needs

Specific management strategy
How do CLAMs fit into the NR manager’s toolbox?
General management needs include:• Policy• Stakeholders• Lake processes• Interventions and land use scenarios• Targets• Justify management

How do CLAMs fit into the NR manager’s toolbox?
General management needs
Tools include:• WQ monitoring• Hydrological modelling• Participation• Field studies• Landuse• Catchment modelling• Decision support tools
(eg. CLAM models)
Specific management strategy
Note: tools inform mgt strategy rather than implement it

Emphasis influenced by:• Policy• Style• Existing knowledge• Lake specifics• Stakeholder expectations
The Search for the NRM El Dorado
An “everything” tool?
All tools are weak in isolation
eg. hydrological modelling data necessary for dynamic modelling and CLAM modelling
eg. WQ monitoring confirm/inform for all modelling
eg. AP interpretation (landuse data) necessary for dynamic export modelling and CLAMs….etc.
CLAMs ideal for data/tool integration
Understanding and maximising CLAMs
Strengths and weaknesses of CLAMs
Management Needs CLAM considerations
Reflect policy (local, state and federal)
Engage stakeholders
Clarify assumptions about lake processes
Consider/propose combinations of management and land use scenarios
Set targets to assess management actions
Justify overall management approach
Understanding and maximising CLAMs
Management Needs CLAM considerations
Reflect policy (local, state and federal)
Local – yes (to the extent that information is available)
State – yes (to the extent that information is available)
Federal – high level
Engage stakeholders
Clarify assumptions about lake processes
Consider/propose combinations of management and land use scenarios
Set targets to assess management actions
Justify overall management approach
Understanding and maximising CLAMs
Management Needs CLAM considerations
Reflect policy (local, state and federal) Anecdotal evidence
Huge variety of parameters
Relatively simple interface
Models very easy to modify
Engage stakeholders
Clarify assumptions about lake processes
Consider/propose combinations of management and land use scenarios
Set targets to assess management actions
Justify overall management approach
Understanding and maximising CLAMs
Management Needs CLAM considerations
Reflect policy (local, state and federal) Integrate wide variety of data
Recognise inherent uncertainty in modelling
However…
No new information on processes
No time-step (dynamic models)
Engage stakeholders
Clarify assumptions about lake processesConsider/propose combinations of management and land use scenarios
Set targets to assess management actions
Justify overall management approach
Understanding and maximising CLAMs
Management Needs CLAM considerations
Reflect policy (local, state and federal) Designed specifically for investigating combinations
However…
Consideration limited to information available
Engage stakeholders
Clarify assumptions about lake processes
Consider/propose combinations of management and land use scenarios
Set targets to assess management actions
Justify overall management approach
Understanding and maximising CLAMs
Management Needs CLAM considerations
Reflect policy (local, state and federal) (ANZECC, policy, expectations)
Engage stakeholders

Understanding and maximising CLAMs
Management Needs CLAM considerations
Reflect policy (local, state and federal) - Integrate data/tools – comprehensive consideration
However…
- Limited to available data
Engage stakeholders
Clarify assumptions about lake processes
Consider/propose combinations of management and land use scenarios
Set targets to assess management actions
Justify overall management approach
Understanding and maximising CLAMs – the data leap of faith
Data vacuum is an occupational hazard
“Anecdotal data” ≠ “no data”
…but CLAMs need data
Do you know your existing land use?
How about riparian planting?
…be prepared to take the leap
So are CLAMs just a series of “hunches”? (combined)
Explicit about assumptions
CLAMs and existing estuary management framework
NSW estuary planning – integrative philosophy
Engage stakeholders
Link with EPS – ID data gaps
Link with EMS – options analysis
CLAM is a means, not an end
Data/tool integration vital – CLAMs ideal
CLAM development – comprehensive consideration
ID data gaps
A data receptacle
Data/tool integration
Help ensure sustainability of ecosystem
AND planning process
CLAMs – it’s all about data/tool integration
