Several different sets of state-level estimates exist in the NWS files for 1978, and in many cases
the estimates do not agree. Data sources are as follows:
. All estimates for California are from the California Office of Emergency Services
(Montane 1999).
. Most of the entries represented by asterisks rather than damage figures are based on
information in Storm Data. In these cases it was apparent that flooding had occurred, but
damage figures were not available.
. The following numbers are from USACE reports: March in Arizona (USACE, Los
Angeles District 1979a); March in Ohio (USACE, Buffalo District 1978); August in New
Mexico (USACE, Albuquerque District 1978); September in Arkansas (US ACE, Little
Rock District 1978); September in Texas (US ACE, Albuquerque District 1979a);
December in Arizona (US ACE, Los Angeles District 1979b and USACE, Los Angeles
District 1980); and December in New Mexico (US ACE, Los Angeles District 1980).
. Montana and Wyoming in May are from a jointly authored USGSINOAA paper (USGS
1984).
. The following estimates are from Marrero (1979): March in Nebraska and Indiana; April
in North Dakota and Virginia; May in Louisiana and Texas; July in Alabama, Minnesota,
and Wisconsin; August in Texas; and September in Louisiana.
. The following estimates are from Storm Data: May in Arkansas; July in Colorado;
August in Illinois, Indiana, and Maryland; and December in Idaho.
. All other estimates are from NWS files.

1979 Flood Damage Estimates
Reconstructed 1979 damage estimates by state and month are shown in Table A-4. Data
sources are listed below. Users of 1979 estimates should note that a flood in "New Jersey, New
York, and southern New England" in January caused $62 million in damage (Marrero 1980).
This estimate could not be assigned to individual states. Similarly, a flood in April in Louisiana,
Mississippi, and Alabama caused $1 billion in damage that could not be assigned to individual
states (Marrero 1980). These floods are included in the national total for 1979, but not in the
state estimates.
. All estimates for Virginia are from the state emergency management office (Michael
Cline, personal communication 2000).
. The following estimates are from Marrero (1980): March in Indiana and Iowa; April in
Texas; July in Texas; September in Maryland, Louisiana, and Texas; October in Kansas
and Florida; and November in Hawaii.
. The following are from USACE reports: March in Minnesota and North Dakota
(USACE, St. Paul District 1979) and June in New Mexico (USACE, Albuquerque
District 1979b).
. Estimates from Storm Data include: February in Arkansas; April in Arkansas, Florida,
Illinois; March in Florida and New York; May in South Dakota; June in Colorado; July in
Alabama, Illinois, New York, and West Virginia; August in Minnesota, Utah, and West
Virginia; and September in Florida.
. February in Hawaii is from USGS (1991).
. April in Ohio is from NWS notes.
. All other estimates are from NWS files.
