A C150 departed as I took Local one. He was slow and outbound for outer point. A DHC2 called inbound for a straight in. I noticed an IFR strip for a Learjet on a Visual approach. He was only seven miles from the field. Much closer than he should have been without being switched to Juneau tower. In addition; he was at 10000 feet. When he finally came over I was expecting a possible go around and handling an unusual situation with an IFR aircraft. At the same time the DHC2 called inbound from outer point. By the time I got back to the Cessna and gave traffic on the DHC2; the Cessna said he saw him and was passed him. All aircraft landed without incident upon arrival the DHC2 was rolling out in the water lane and the pilot said; 'hey tower I saw that Cessna as he passed my windshield.' The Cessna was not equipped with a transponder. It was outside my class Delta airspace and I was handling an unusual situation with an IFR Learjet. The pilot called and complained on the traffic call and a newly certified CIC took the call. The CIC mistakenly checked significant and filed as an NMAC instead of public inquiry. It was two VFR airplanes outside my airspace and I was giving priority handling to an IFR aircraft.
JNU Tower Controller was informed of an NMAC between a DHC2 landing on the water lane and a C150 that had departed opposite direction a few minutes earlier from the paved runway. Both aircraft were VFR and the C150 was not transponder equipped.
