salvage these fish. Each crew was to be equipped with a truck supplied with
a sizeable quantity of dry ice and scheduled to generally follow the center
of activity and retrieve as many fish as possible. Once loaded to icing
capacity, salvage units were to transport their fish to refrigeration
facilities at the state. fish rearing station at Boulder for storage until
distribution to public and charitable agencies could be effected. For general
public relations purposes and maximum fish utilization, all creel limits in
the treatment area were lifted prior to the treatment program.
There are several communities of varying size along the treated
reaches of the Green River. As there seemed to be some possibility of dead-
fish nuisance problem at these points, one crew of men was assigned the
responsibility of dead-fish removal if the circumstances dictated.
The Wyoming communities of Fontenelle, Green River and Rock Springs
and the Utah community of Dutch John all obtain their municipal water supplies
from within the treatment area of the Green River. For this reason, it was
mandatory to obtain project clearance from the Wyoming Department of Environ-
mental Health, the Utah State Department of Public Health and the U.S. Public
Health Service. These agencies not only provided the necessary clearance
but also valuable assistance in directing coordinated water supply manipula-
tions and auxiliary treatments for taste and odor control. The U.S. Public
Health Service personnel were to maintain water quality checks on municipal
water supplies during periods of maximum rotenone concentrations past supply
intakes. A brief summary of the U.S. Public Health Service activities as part
of this project is included as Addendum 1.
The Final Details
As previously described, a general estimate of rotenone requirements
was made for every station of the project. Throughout the summer of 1962
checks at U.S. Geological Survey gauging stations provided current information
on stream-flow developments, and, by the latter part of August it was possible
to make a reasonably exact estimate of the maximum rotenone gallonage for
every station. Based on this information, the total rotenone requirement
for each station was calculated in 30 and 55 gallon barrel combinations.
Because of possible vandalism, station stockpiles were not set out until the
week prior to the treatment, during which time they-were under continual
surveillance.
Immediately prior to the start of treatment on September 2 and 3,
a final series of water-flow checks were made at all Government gauging
stations. Where no permanent gauging equipment was available, last minute
recordings were made with a portable flow meter. Based on these data, final
rotenone flow figures were calculated for every toxicant dispensing station
on the project and distributed to respective personnel (Appendix G and H).
Review Of Operation
At 0800 on September ~+, 1962, the number one stations an the New Fork
and Green Rivers were placed in operation. Thereafter, chemical treatment
continued uninterrupted until its completion on the morning of September 7.
