water extended as far south as the reef and, at that time,

as far east as Bird Cay and out to a line running to the

eastern tip of Cas Cay. The area around Station 3, south of

Compass Point, was not noticeably affected at that time. The

turbidity was highest, of course, in the northern reaches of

the Lagoon proper and throughout the channel north of Bovoni

Cay. The bottom was visible at Stations 2 and 3 and points

southeast and the surf cresting over the reef to the south

presented an effective barrier to the further southward spread

of the plume. Besides the considerable amounts of mud still

in suspension, quite a lot had already settled and was dis-

turbed by the boat's prop. At approximately 4:30 p.m. on

May 11, with the tide at or near low slac; there was good

flow of very turbid water from at least two points on the

north shore, one adjacent to Station 10, the other farther

west.

 On May 13 little improvement was noted. A traverse

from Station 10 to 11 stirred up large amounts of brown mud.

By May 18 there was improvement in some areas, most notably

at Station 11 and southward, where clean, sandy bottom with

open worm holes was visible. Clearing to a lesser extent

was noted north of Station 11 with increasing amounts of

settled clay and turbidity toward the shore where there was

still no evidence of improvement. By May 20, however, the
