OPERATIONS
There were no operations in December 1999.
OPERATIONS
There have been no operations so far in 2000.
With the predicted high temperatures and low water levels for the rest of the year,
this may change quickly.
PUBLIC SAFETY DIVERS COMPETITION
The Team will not be competing in this year's
Public Safety Divers Competition.
Too many of our senior divers and surface support personnel
(including about half of last year's competition team)
are scheduled to be out of town March 13 and 14. Wait until next year...
NEXT MEETING and TRAINING
The April meeting will be held in conjunction with the April Training Dive
on (no fooling) April 1.
The April training dive will be
Saturday April 1
at 10:00 am
at the Lake Travis Test Station.
We will review all of the patterns and signals to get ready for the season opener
in May.
At the March training dive we worked on weight adjustment.
|
|
Divers assemble their gear and go over the day's assignment:
wearing a nearly empty tank at the surface, set your weight to be slightly positive
on a full inhale and slightly negative on full exhale. Dean shows about where the
water level should be.
|
|
|
|
Several divers had to make adjustments on new or recently modified equipment.

OPERATIONS
March 18, 2000 -
Shortly before 4 pm on Saturday March 18 the Dive Team was called to
Windy Point park to search for a missing diver.
The subject was reported missing in deep water around the old pecan groves.
Search teams encountered very difficult diving conditions in the primary search area,
with near zero visibility on a steep slope densely covered with old trees and underbrush.
Divers spent several days searching from 60 to 130 feet deep.
Deep search teams found the dense trees and near zero visibility extending past 130 feet
in the search area.
The subject was finally located on March 30.
The April 22, 2000 Training Dive
was a simulated recovery operation following an assault in a boat.
Divers had to locate the victim and then conduct an evidence search
and recovery operation for the weapon.
DELL FOUNDATION GRANT
The Dell Foundation has given the Dive Team a generous grant to support its operations.
Team members and Dell empolyees Mark, Rick, Wayne, and Jason worked on the application
for support of emloyees in community service organizations, and their hard work paid off.
The Dive Team has a new domain name and web site address:
http://tcdt.org.
(http://www.tcdt.org will also work.)
The new site should be faster and more reliable, and we will be adding new services
in the next few months.
OPERATIONS
March 18, 2000 -
The operation that began on March 18 at Windy Point Park was finally completed
when the subject was located on March 30.
Most of the search was carried out in 90 to 130 feet of water with zero visibility
among dense trees in the old pecan groves.
The subject was located in approximately 120 feet of water.
These pictures are from Monday March 20 when teams first extended the search area
to water 130 feet deep.
|
|
Divers begin the day by reviewing witnesses' statements and search conditions encountered
on the previous two days.
Due to the high wind and dense trees in the search area, divers decided to mark the deep side
of the primary search area with a buoy on a heavy rail anchor.
Lewis and Dennis discuss where to position the buoy as Tim checks the ugly but functional anchor.
|
|
|
Dean, Mike, and Paul T. rig the decompression stop reserve tank while Paul E. directs
team members on board Lake Patrol 20 into position to set the marker buoy.
Dive Team members who had run three very deep patterns debrief with LCRA divers
preparing to run sweeps along the uphill side of the search area.
|
The Sheriff's Office is converting to full crews of paid personnel on patrol boats.
The Dive Team has been training Sheriff's officers in using full face masks
and in search and recovery diving.
They can deploy fast small area searches from TCSO and LCRA boat crews,
with the Dive Team in reserve for large scale recovery operations.
OPERATIONS
On Sunday May 7 a swimmer was reported missing at Hippie Hollow park at about 6:30 pm.
The Dive Team was dispatched at 6:51 pm.

at about 7:30 pm a child was reported missing in the Colorado River near Caldwell Lane.
The Dive Team was dispatched to the incident at 8:46 pm.
Witnesses reported that the child was last seen in swift water in the main channel.
Divers encountered fast moving water up to 9 feet deep with visibility about 6 inches.
Divers conducted a drift search for about 100 yards downstream from the PLS
and three circle patterns around the PLS and downstream. Search operations were suspended
at about 1:00 am due to rapidly rising water.
Search operations resumed at 9:00 am on Sunday June 18.
Dive Team members were joined by divers from the Sheriff's Office underwater recovery team.
SETCO Volunteer Fire Department and area residents provided onshore and boat support.
Travis County Search and Rescue sent personnel and a water search dog, and
Austin EMS set up a rehab center.
Travis County Fire Control members searched the north shoreline.
Divers enlarged the drift search area and searched through a large number of snags,
strainers, and other obstructions for about a mile downstream from the PLS.
Boats and Starflight made several passes downstream searching the shoreline
while walking and wading searchers worked through overhanging vegetation.
Search operations continued in temperatures over 90° and near 100% humidity
until about 5:30 pm.
The subject was recovered on Monday June 19 approximately 8 to 10 miles downstream
from the search area.

Divers from the Dive Team and the
Sheriff's Office Underwater Recovery Team go over the previous night's operations
and plan search strategy. Dive operations began at 11:30 am after the river had
dropped to near the same depth as the previous night. The PLS is the snag
near the far bank, just above the outboard motor in the picture at left

the new SCUBA diving area on the basin side near the dam.
OPERATION AND NON-OPERATIONS
On Saturday July 1 shortly after 1:00 pm the Sheriff's office received a report
that a recreational diver had found possible human remains near the Mansfield Dam
Park swim area. Officials at the scene decided to investigate certain unusual aspects
of the reported discovery - an intact human skeleton hanging from a tree by a rope underwater -
before committing a full search and recovery operation.
Divers from the Sheriff's office and the Dive Team investigated and found
what appeared to be old props from a Halloween "Haunted House" dive.
On Sunday August 20 at approximately 7:20 pm a swimmer was reported missing
near the sandbar off Windy Point Park.
Divers from the Sheriff's office and LCRA recovered the subject in 15 feet of water
at approximately 9:22 pm using some equipment from the Dive Team Trailer.
On Sunday August 27 starting at approximately 5:53 pm
the Sheriff's office began receiving reports of missing swimmers near Briarcliff Marina
and near Graveyard Point.
By 6:30 pm it had been determined that callers had misidentified Hurst Harbor as Briarcliff
and all operations were relocated at Graveyard Point.
Divers from TCSO and LCRA had not located the subject Sunday night and suspended their search
until Monday morning.
The Dive Team was called to assist in the search on Monday August 28.
The search area was downstream from Armadillo Cove along Graveyard Point.
Divers from the Dive Team, TCSO, and LCRA covered four long line sweeps across the area.
Visibility was poor, ranging from zero to occasionally 2 feet.
The subject had not been located by 4:00 pm. Surface search operations were scheduled to
resume on Tuesday morning, and the subject was recovered on Tuesday.

There was no separate Dive Team training dive in September due to the long operational dives
in late August and early September. Several Team members got experience working in
mixed-agency search teams on
August 28
and
September 4
operations.
The Travis County Sheriff's Underwater Recovery Team has training dives scheduled for
Friday, September 22 at 9:00 am and Friday, October 20 at 9:00 am.

|
| |
The search area was the mouth of the swimming cove at Mansfield Dam Park, just above the main
river channel.
The reported
PLS
is between the small black and orange buoy and the third orange no-boat buoy
in the picture at left.
A search team of divers from the Dive Team, TCSO, and LCRA first swept a 180° area
upslope from the search anchor.
The search team gets their final instructions in the picture at right.
|
 |
|
| |
While the first search team worked their pattern a second team with deep diving experience and
equipment prepared to sweep the area downslope from the search anchor.
The downslope side of the search area drops quickly to the old main channel.
Members of the first search team debriefed the deep search team on bottom terrain and visibility.
|
 |
|
| |
The deep search team located the subject in 75 feet of water
approximately 60 feet from the search anchor.
The
location marker
is the small yellow Pelican just inside the two rightmost orange no-boat buoys
in the picture at left. Three divers have surfaced and two others are bringing the subject
to the surface. At right an LCRA boat moves in to complete the recovery.
