The purpose of this paper is to identify the drag penalties for a number of simple SCUBA configurations. This is achieved through scale model experiments conducted in a wind tunnel. Some comments on the associated energy requirements are made, and from these, the effect on a diver’s bottom time is briefly addressed. The configurations tested include a study of the effect of the equipment configuration and the effect of small changes to the diver incidence.
River diving can place exceptional physical demands on the diver. Thus, river divers should be in good, if not superb, physical condition. Crawling around a river bottom will require upper body strength. Divers should pace themselves and be cognizant of the stamina of the smallest person of the buddy team. Moving against the current can be fatiguing and can rapidly deplete air supply.

Last weekend at our regularly scheduled "Second Saturday" exercise,(at Battleground Lake this time) two current members finished up their Full Face Mask certification, while 3 prospective members (including two certified and actively working commercial divers) observed the exercises.
We've just confirmed with Clackamas County Sheriff’s Office that NW SAR Con will not be held in 2017. Due to resource constraints, the program will resume next year, Sep 21-23, 2018.
