Operations, Construction, and Readiness Divi-
sion in August 1991 to field elements throughout
the country. As the cover letter directed, each re-
ceiving Operations Office was to distribute cop-
ies of the questionnaire to all lockmasters, dam
operators, operators of other hydraulic struc-
tures, and other pertinent personnel. No replies
were sought from the division level. Replies were
received through November 1991.
Survey response data
Considering only the 49 states exclusive of
Hawaii, and treating the New England Division
as equivalent to an Engineer District, the survey
brought replies from projects and elements with-
in 28 districts. This is out of a possible total of 37
districts, for an overall reply rate of 76%.
From among the 28 responding districts, re-
plies to the survey were received from a total of
235 Corps water resources projects.* In some
cases more than one reply was received from a
single project. This usually involved replies from
one or more of the following elements: lock and
dam operations, hydroelectric generation, natu-
