Purpose

• Understand which basins affect which areas of the bay and by how much

Page 3: Geographic Isolation Scenarios

Procedure

• Set the Susquehanna at Tier 3 loads and all other watersheds at 2000 levels

• Record the relative change in attainment for each criterion and designated use area

• Repeat for each basin

Page 4: Geographic Isolation Scenarios

Progress

• All basins completed

• Incorporated improvements in process

• Results are provisional

Page 5: Geographic Isolation Scenarios

Why Still Provisional

• Small changes difficult to compare to large changes

• Different basins have different N:P:Sed ratios

Presentation Rules

• Do not show normalized results for Patuxent or ESVA.

• Do not consider changes below a particular threshold to be significant

• CL spring = 0.0011• CL summer = 0.005• KE = 0.0006

Page 10: Geographic Isolation Scenarios

Other Considerations

• Final criteria curves not implemented

• Final model applications areas not decided

• Final designated use boundaries and clarity depths not decided

Page 11: Geographic Isolation Scenarios

Results

• Problems (red areas)

• Who has biggest impact

• Who has biggest relative effectiveness

Preliminary Findings - Clarity

• Local Problem

• Susquehanna influence felt in upper half of bay

Page 121: Geographic Isolation Scenarios

Preliminary Findings - Chlorophyll

• Local Problem

• Susquehanna influence felt in upper half of bay

Page 122: Geographic Isolation Scenarios

Preliminary Findings – DO Deep Channel

• CB3 through CB5

• Susquehanna influence strong but decreasing

• Rappahannock and north have strong local effect

• James and York are minor effects

• POTMH is part of the mainstem

Page 123: Geographic Isolation Scenarios

Preliminary Findings – DO Deep Water

• Similar to DO Deep Channel, but the local effect is more pronounced.

Page 124: Geographic Isolation Scenarios

Still to Come

• Revise with new criteria bioreference curves, designated use boundaries, and clarity depths.

• After tidal fresh allocations are made, do a similar analysis to inform the final allocation decisions.
