TENDERS

At the time of the Coast Guard's taking over of the Lighthouse Service in the 13th Naval District, the tenders HEATHER, ROSE, MANZANITA, RHODODENDRON, and FIR were all operating in the district and became the property of the United States Coast Guard. Prior to the consolidation and upon the arrival of the FIR within the district, HEATHER had been removed from duty and tied to the sea wall at Lake Union Locks until the outbreak of war. At that time the Army borrowed her and she was never returned.

At the outbreak of the war, the MANZANITA was fitted out and supplied with special submarine cables for the laying of a protective loop across the approach to Dutch Harbor and again, she was loaned to the Canadian authorities for the laying of a similar cable at Prince Rupert. The tenders performed their regular duties during the war, but were equipped with small arms, depth charge racks, and deck guns for protection from submarines. The armament was removed following the cessation of hostilities and the complements of the tenders were thereby gradually reduced.

Two fine tenders were commissioned and attached to the 13th Naval District during the war, the BASSWOOD, 1944, and the BLUEBELL, the following year. The Basswood was transferred after a year's general aide to navigation duty which involved servicing the isolated units and the LORAN project on Vancouver Island. In addition to these large tenders, the CO-65302-D was added and employed in buoy work and the maintenance of minor aids on the Upper Columbia River between The Dalles, Oregon and Pasco, Washington.

With the scarcity of Coast Guard Cutters in this district during the war, a vast amount of the assistance work fell upon the tenders. The increased size of the fishing fleet had the effect of causing more rescue operations, and in these, the tenders did an extraordinarily fine job.

RADIO BEACONS

At the time of the consolidation of the Lighthouse Service and the Coast Guard, the Seattle District operated nine land-based radio beacons and four radio beacons on the lightships. Two beacons were under construction at Destruction Island (completed in 1943) and at Willapa Bay (completed in 1941). Two more radio beacons were authorized in 1942, one at Cape Flattery (Tatoosh Island) and one at West Point. In the middle of 1945, the radio beacon at Ediz Hook was established, bringing the total number of District radio beacons to 18. However, at the onset of the war, the Navy removed the lightships from the Umatilla Reef and Swiftsure Bank thus leaving only 16 beacons in operation. Of these 16, one was maintained by the RELIEF LIGHTSHIP and used alternatively on the Columbia River station.

A monitor station was established at North Head Radio Station which checked the performance of all District Radio Beacons, and outlying stations were notified daily of all failures or defects in the radio beacons' operation. These reports were a District innovation and were not required by Headquarters but were merely another measure adopted by the District Coast Guard Office for increased efficiency in the District system. In March, 1944, Radio Station Meadowdale was ??? as a Monitoring Station for radio beacons, as the activities at that station had been considerably reduced. Although Headquarters' instructions ordered that each radio beacon in the United States be monitored at least once every four hours, it became possible in the 13th Naval District, to monitor each radio beacon every hour after the new monitor station had been added.

AIDS TO NAVIGATION IN UPPER COLUMBIA RIVER

In 1932 navigation in the Upper Columbia was revived for the transportation of wheat, but the servies between the Upper and Lower Ports was intermittent. This renewal of navigation was more or less on a trial basis to determine if sufficient commerce could be developed to support water carrier operation. Sufficient traffic was realized and, after the construction of the Bonneville Dam which was completed in 1938, river traffic expanded into the movement of great steel barges designed to carry liquid petroleum in the hull and package or bulk cargo on deck. With this increased traffic from Astoria, Oregon, beyond The Dalles, Oregon, the necessity of navigational aids to insure the mariner's safety became most apparent. As a result, the Aids to Navigation Section centered the majority of its activities in the promotion of safe navigation along the river. Here was the proving grounds for experimental light structures and buoys to determine those most suitable for the area. Due to the rapid current, range marking channels had to be so perfected as to enable the mariners to ascertain their course in a matter of seconds.

It was also necessary to experiment with range markings, and in this connection the Nautical Scientist in the Aide to Navigation Section, 13th Naval District, invented and constructed a system of laterally restricted range markings. This newly devised "Channel Limiting Group" was necessary because of the impossible terrain which made the establishment of the conventional markings impracticable if not impossible. With Headquarters' approval an experimental range was established on the Columbia River near Arlington, Oregon, which proved to be successful. Other experiments were concerned principally with surface riding buoys and fast water buoys.

The construction of Grand Coulee Dam which created Roosevelt Lake, extending almost two-hundred miles from Mason City, Oregon to the Canadian Border, also placed additional work on the Aide to Navigation Section. The Law Officer in March, 1944, advised that Roosevelt Lake was navigable; and after an investigation the Aids to Navigation Officer installed 27 lights and 10 reflectors in those waters. The aids are serviced at the Seattle Operating Base twice a year, and the Bureau of Reclamation offered the use of one of its boats for establishing and maintaining these aids.

ANRAC ??? EQUIPMENT

The enforcement of blackout in the United States at the outbreak of the war made it necessary to extinguish or silence the navigational aids in the continental waters in addition to the blackout of municipal lights. To perform this action by manual
