16 U. S. BUREAU OF FISHERIES. 
CONDITIONS. 
1. All persons desiring to erect and maintain fish weirs, traps, or pounds 
under this authority shall nrake application to the District Engineer, United 
States Engineer Office, Seattle, Wash., giving their names, their addresses, the 
proposed location of their weir, trap, or pound, and evidence that the proper 
license has been granted by the Territory of Alaska. 
2. That no floating fish trap shall exceed 2,400 feet in length over all, nor be 
constructed and operated in more than 100 feet depth of water at the outer 
end of the trap at mean high tide, according to the United States tide tables, 
with the exception that a floating trap may be constructed and operated in a 
greater depth of water, provided the extension measured from the shore line 
at mean high tide does not exceed 1,000 feet over all. 
3. That all the apparatus used and the work herein authorized shall be sub- 
ject to the supervision and approval of the aforesaid district engineer, who may 
temporarily suspend the work at any time if, in his judgment, the interests of 
navigation so require. 
4. That no weir, trap, or pound shall be located or built in such place or 
nranner as to unreasonably obstruct or interfere with navigation. 
5. That on the outer end of the weir, trap, or pound the permittee or owner 
shall maintain a sign inscribed with the license number in numerals not less 
than 6 inches in height, capable of being readily read from passing vessels, 
and failure to keep such sign conspicuously displayed shall be sufficient reason 
for the cancellation of this authority and for prosecution as provided in the 
next paragraph. All renewals of the Territorial license shall be reported to 
the aforesaid district engineer when they occur, together with the Territorial 
license number. All changes of ownership shall also be reported to him imme- 
diately, and the permit shall be returned to him for proper notation thereon 
of such changes. 
6. That upon the abandonment of the location or upon ceasing to use any 
weir, trap, or pound, as hereby authorized, the permit and the map or maps 
attached thereto shall be immediately returned to the aforesaid district engi- 
neer, with notice of the abandonment, and the owner shall immediately remove 
the structure at his own expense, including all piling, stakes, ete., to the satis- 
faction of the aforesaid district engineer. Failure to so remove the same shall 
be considered good ground for prosecution of the permittee or owner for main- 
taining an illegal structure endangering navigation, as set forth in sections 10 
and 12 of the river and harbor act of March 3, 1899: Provided, That if the 
use of said structure is suspended temporarily it may be maintained in whole 
or in part if the license number is conspicuously displayed and the trap is prop- 
erly lighted or otherwise marked, as may be necessary to prevent unreasonable 
obstruction to navigation. Any fish weir, trap, or pound allowed to go into a 
condition of disrepair so that it can not be readily seen, or on which the license 
number is not conspicuously displayed, will be regarded as abandoned, and if 
not promptly removed or marked as above provided will subject the permittee 
or owner to prosecution, and any trap not in use on which the license number is 
not displayed will be subject to removal by the United States at any time. 
7. That if future operations by the United States require an alteration in the 
position of the weir, trap, or pound, or if the latter, in the opinion of the Sec- 
retary of War, shall cause unreasonable obstructions to the free navigation of 
the said waters, the permittee will be required, upon due notice from the Sec- 
retary of War, and within 30 days thereafter, to remove or alter the weir, 
trap, or pound, or obstruction caused thereby, without expense to the United 
States, so as to render navigation reasonably free, easy, and unobstructed. No 
claim shall be made against the United States on account of such removals or 
alterations. 
8. That fishing structures and appliances in navigable waters of the United 
States shall be lighted for the safety of navigation, as follows: 
“The lights shall be displayed between sunset and sunrise. They shall be 
placed at each end of the structure, excepting where the inner end terminates 
in such situation that there is no practicable navigation between it and the 
high-water line of the adjacent coast, in which case no inner light shall be dis- 
played. ‘“he outer light shall be white and the inner light shall be red. The 
size, capacity, and manner of maintenance of the lights shall be such as may 
be specified in the War Department permit authorizing the erection of the struc- 
ture or appliance,
