Description
Flood Information
The Swan River has flooded numerous times since European arrival in 1829. In July 1830, barely a year after the establishment of the colony, the river rose 6 metres above its normal level.
Other abnormal floods events occurred in the winters of 1847 and 1860.
The flood of July 1926 resulted in the washing away of the Upper Swan Bridge and a section of the Fremantle Railway Bridge. The Fremantle bridge partially collapsed on 22 July 1926, five minutes after a train containing schoolchildren had passed over! No one was injured in the collapse, however it created major disruption to commerce for several months. Repairs were completed and the bridge reopened on 12 October 1926.
The last significant flooding occured in 1983.

This is a History Cache, to log the cache you will need to do the following;
- To answer the questions look to the right hand side of the geocache listing page. Under Actions there will a link called Questions and Answers Get Codeword. Geocachers looking to answer the questions and get a codeword will click on that link where they will be able to answer the questions.
- A codeword is created when all answers are correct.
- A delay of 120 seconds (2 minutes) per incorrect answer applies in the event of the geocacher getting an answer wrong.
- Copy and paste the codeword into the codeword box on the log page to validate the log.
And the 4 questions are;
1. What colour band listed on the map legend and on power poles in the area denotes the 25 year flood zone?
2. What colour band listed on the map legend and on power poles in the area denotes the 100 year flood zone?
3. Right next to the map is a vertical flood gauge. What is the highest reading?
4. About 1m from the sign is a Swan River Heritage Trail Marker. Which flora IS NOT listed?

I was armchairing and was not meant to log this cache,
Please accept my apologies,

Lovely spot, thanks for another reason to return for another visit.
Thanks for bringing me here
Interesting piece of local history, thank you SpatialRiq!
2. On the MAP, what colour is used to denote the 100 year flood zone?
In my opinion I had to answer these questions wrong to get the codeword. The questions need to be worded better as the colours on the actual MAP and also contained in the 'MAP KEY' are not the same as lampost colours which are not part of any map on the sign.
Thanks for the cache.
Good work SpatialRiq. Thanks for the history lesson.
