Dams Sector Consequence-Based Top Screen Methodology

• If available, provide the estimated value of M 2 .
• Describe the agricultural markets or regions served by the facility.
• Indicate how the values selected above for annual water deliveries were obtained. Please
identify relevant data sources and reference materials (if applicable, include title, author,
date, and/or version of any report, study and/or data source used as reference).
Hydropower Generation: Provide an approximated estimate for the hydropower generation
capacity of the facility by selecting the appropriate range from the table below.
Installed Generating Capacity, M 3
Level
M 3 (MW)
1 M 3 > 8,000
2 4,000 < M 3 ≤ 8,000
3 2,000 < M 3 ≤ 4,000
4 1,000 < M 3 ≤ 2,000
5 500 < M 3 ≤ 1,000
6 250 < M 3 ≤ 500
7 0 < M 3 ≤ 250
8 M 3 = 0
• If available, provide the estimated value of M 3 .
• Number of generating units:
Flood Damage Reduction: Provide an approximated estimate of the value of average annual
flood damages prevented (damages resulting from seasonal flooding) by selecting the
appropriate range from the table below.
Average Annual Flood Damages Prevented, (M 4 )
Level
M 4 (Millions of Dollars /Year)
1 M 4 > 800
2 400 < M 4 ≤ 800
3 200 < M 4 ≤ 400
4 100 < M 4 ≤ 200
5 50 < M 4 ≤ 100
6 25 < M 4 ≤ 50
7 0 < M 4 ≤ 25
8 M 4 = 0
