the gage.
6.9.2.2 Frequency: Do every 5 to 10 years:, or when floods or
vandals cause noticeable movement.

0.02.

6.10 The wiring Harness
6.10.1 Discussi'Jn
In order for the flood a1a.rm to operate, the float wires
must be hooked up in the p:r'oper sequence. The lower and
middle floats are hooked up in series between terminals 1 and
4. The upper float is hook.e,d up be!t:ween terminals 3 and 4,
The ground wire that comes out of the! circuit board, is con-
nected to terminal 7. A simplified wiring diagram for the
floats in their normal (non-flood) position is shown in Fig-
ure 7.

7. COMMENTS AND RECOMMENDATIONS
7.1 Number of Automated Flood Detect:ion Gages in the Flood
Warning System.
The two options for the configuration of the Wiggins Flood
Warning System 'r/ere presented in Part: 3.2. The options are
similar, except that Option <: provides for an automated flood
detection gage at the Highwcl.y 52 sit:e and Option 1 provides
for only a staff gage at that: location. Based upon the fol-
lowing reasons, it is recommended t:hat Option 2 be adopted.
Two alarm gages should be used because:
7.1.1 There appears to be insufficient warning 1:ime for
erection of the closure structures" using the downstream
(County Road) 'r/arning gage a.lone, durinc:f those floods that
would necessita.te closure of the Burlington Northern Railroad
and Highway 6 l,evee gaps.
