The Lewisville (TX) Fire Department has been in the dive-rescue business since the early 1980s. These members are responsible for the EMS, fire, and rescue services on the 35,000-acre Lake Lewisville, which attracts more than 2.7 million visitors annually. More than 300,000 people live adjacent or have indirect access to the lake, which has marinas, restaurants, and beach areas and plays host to the Bass Masters Tournament and several other large events. It is easily accessible, located a few minutes north of downtown Dallas off I-35E. The team responds to about 300 to 400 calls a year. Over the years, Lewisville’s Dive-Rescue Team has grown to include almost 60 divers, two dive-rescue units, and two fire boats; it serves as the dive team for many communities in the Dallas-Fort Worth Metroplex.

The team has seen its share of challenges related to keeping members trained and properly equipped. Fortunately, the city’s administration, the mayor, and the council have provided the team with state-of-the-art equipment and have provided the funds to have team coordinators Captain Todd Staton and Engineer B.A. Reaves certified as Dive Rescue International instructors. Up to now, we have been able to train in our city’s public swimming pools and the lake. As with fire suppression training, it’s nice to be able to train a diver in an environment that is safe and controlled, as in a smoke or burn building, and then graduate to more and more difficult tasks and scenarios, preparing for the real thing in the long run.

Since the tank’s dedication, membership on the Lewisville Dive Team has grown to almost 60.



Most of our dive rescue responses start in the rescue mode; sometimes, they must be switched to the recovery mode. At these times, the divers must operate under the pressure of being observed by the victim’s family members and the public. Adding to the pressures is that diving is extremely dangerous, especially when diving in black water. Our team lost the use of the city’s pools for training when the city, responding to citizens’ requests, converted the city’s swimming pools into water parks for the residents. That left the dive team with only the lake in which to practice. This was satisfactory for our experienced divers but presented obstacles when it came to training the majority of our divers, especially the new team members.

One of our dive team captains, Kevin Brule, proposed the construction of a training tool that would enable us to get our divers back into the water more often, and in a controlled environment. The proposal was to build a swimming pool behind our Firehouse 2, which also serves as the main dive-rescue station. Our administration granted the request. We contracted with BMR Pools, owned by two of our firefighters. The pool was designed to be approximately 40 by 25 feet in size and from four to 15 feet deep (photos 4-7). It had a black pebble finish (Gunite®), which presents a little darker atmosphere, and a salt-water filtration system that would be less harsh on the dive gear and equipment than chlorine.

(9) The amount and variety of dive training that can be accomplished with this tank are pretty much limitless.

All five divers assigned to each shift at Firehouse 2, where the pool is, and divers assigned to the other firehouses can train in the water pretty much any time they want (photo 8). It also provides the team with the opportunity to swim laps and log them. with their other training exercises, in their dive log books (photos 9, 10).

(10) The same “darkening” effect can be accomplished in the dive tank as in a burn building when using a darkened-out face piece drill.

An air fill station was added to Firehouse 2 as well so that the divers do not have to travel to refill their bottles. The other big difference in using this new facility instead of the lake for training is that, when training in the lake, two units had to be placed out of service for a significant time because of the time it took to travel to the lake and the cleanup afterward. Now, the team members for the most part can stay in service and respond with a minor delay, if any (photo 11).

(11) Access to the dive equipment on the dive rescue unit can easily be made through a gate on the side. It also allows the tank to be used for the department’s annual pump testing in the absence of a drafting pit or tank.

Probably the biggest challenge was to get the troops to call the pool the “Shark Tank” instead of the “pool.” At a time when many city departments are under the microscope, we didn’t want to leave anyone with the idea that money was spent to build a recreational pool behind the firehouse. So, we call it “Shark Tank,” and it has given our divers the opportunity to practice their diving skills much more often than in the past. Most are diving three to four times as much, and their skills are improving (photos 12-14). The dive team coordinator has them training on their skills so that if they should get in trouble while underwater, it will be second nature for them to get themselves out of harm’s way.
