Presentation Outline

 Overview of our assignment  Draft Report – major findings  Tiered application of the Decision Support Tool  Major comments and revisions to Draft Report  Looking ahead to implementation

Alliance Mission

Priority Actions

Funding Opportunities Stakeholder desires and concerns Knowledge of Lake and watershed management

3

Local Voices: Priorities

 Human health concerns  Protect recreational

access- economic driver

 Need for collaboration and

coordination

 Fear that lake has reached

a tipping point

 Need to document and

communicate progress

4

Multi-criteria Analysis (MCA)

 Set up an evaluation matrix (project alternatives and

evaluation criteria)

 Assign weighting factors to each criterion

 Indicates relative importance compared with other

criteria

 Assign scores for ‘desirability’ under each criterion for

each alternative

5

Criteria

Common Watershed In-lake

Scoring

6

Criteria: All Projects

 Consistent with plans, strategies, or successes  Broadly supported  Costs are understood  Magnitude of costs  Potential for outside funding  Plan to measure and report effectiveness

7

Criteria: Watershed Projects

 Reduction in nutrient loading  Reduction in sediment loading  Hydrologic resilience

8

Criteria: In-lake Projects

 Protective of human health  Protective of ecosystem health  Longevity of effectiveness  Reduce nutrients in ecosystem  Manage invasive species  Enhance recreational uses

9

Scoring

 Scaled as 0,3,6,9  Specific guidelines  Potential role for scientific advisors for technical

scoring

10

Application

 Define the project

 Document assumptions  Determine whether to include all criteria

 Assign scores for criteria

 Matrix math to multiply weights; add and total

 Use totals as a guide to implementation

 Build partnerships with land owners  Justify and request non-local cost sharing

11

Tiered Application of Tool

 Three levels: Tiers 1, 2, and 3  Increasing level of detail and specificity  Began working with foundations to test-drive tool

12

Comment

TMDL is widely acknowledged to be an estimate. Is it reasonable to use it to set priorities?

 Models are estimates  Uncertainties abound, especially internal loading  Data gaps: stream monitoring and profile sampling  Precision Conservation approach

13

Comment

Sediment load should be uncoupled from TMDL

 Agree  Modified scoring criteria for projects designed to reduce

erosion and sedimentation

 Referenced standard percent reductions from best

management practices

14

Comment

Too much emphasis on nutrient inactivation

 Prescient, based on NYSDEC progress  Kept recommendation to estimate internal loading  Added hypolimnetic oxygenation  Expanded discussion of dredging (and arsenic)

15

Comment

Who decides about scores?

 Added external references- e.g., USEPA classification of

chemical toxicity

 Retained suggestion of suggested role for Alliance’s

science advisors

Proportional Allocation

 Comments from all perspectives  Did not change  Important to remain flexible- adapt to opportunities  Monitoring- address significant data gaps, provide a

basis for adaptive management

 Encourage all projects to define and measure success
