of these states was computed as the product of
the local evaporation rate multiplied by the
water-surface area in the bays, lagoons, reser-
voirs, lakes, ponds, and streams within the
subdivision.
Evaporation rates were taken from the map
of Kohler, Nordenson, and Baker (1959); the
western part of which is reproduced in this
report at a larger scale. It shows isopleths
of annual lake evaporation, derived from avail-
able evaporation-pan data and computed from
meteorological records by the techniques
developed during the comprehensive evaporation
investigations at Lake Hefner and Lake Mead.
Water-surface areas for the larger reservoirs
and regulated lakes were taken from Thomas and
Harbeck (1956), who presented conditions as of
January 1, 1954. Water-surface areas were
individually measured on recent maps for coastal
bays and lagoons; principal inland salt lakes
natural freshwater lakes of 500 acres or more;
and for the larger streams and canals. A
sampling procedure was used for estimating the
total areas of the many small stock ponds,
reservoirs, lakes smaller than 500 acres; and
minor streams and canals. All the identifiable
bodies of water were measured on selected maps
or aerial photographs within each 1° quadrangle;
and from the sample data, the total water-
surface areas shown on maps and photographs and
listed in available reports usually present
full-pool or bankful conditions, most of the
observed areas were reduced to arrive at the
average effective area subject to evaporation.
Maps and tables present the estimated water-
surface areas and the amounts of evaporation,
subdivided by States and also by principal
river basins.
