DMG

Underwater encounters are divided into those which occur in fresh water
and those in salt water (seas and oceans). Each diviion is further broken
down by depth -- shallow and deep water encounters. In fresh water,
shallow water encounters occur at 50' or less depth (where the vision is
relatively easy). In salt water, shallow water encounters occur to twice that
depth, i.e., 100'. As a reminder, the max. depth for shallow water encounters
is shown in (parentheses) after the designation. The numbers of
monsters encountered are those shown in the MM.

When a random monster encounter is indicated, go to the appropriate
portion of the table and roll percentile dice. Read down the Dice Score
column until the total of the dice is found, then read right to find the
creature encountered. Inappropriate encounters should be ignored and a
new #number# generated in order to gain a reasonable result. Number of
creatures encountered should be appro. to the strength of the encountering party.
