The Dickson Wetlands were built in 2011. Wetlands improve the quality of urban stormwater by trapping suspended solids, nitrogen and phosphorous. These are an example of an off-line wetland. Low stormwater flows along the Sullivans Creek channel are diverted into the wetland by a weir to the north of the starting coordinates for this cache. On big rainfall events, most of the stormwater zooms past the wetland straight down the channel and onto the Lyneham wetlands further downstream.
This multi cache takes you on a short journey around the pretty Dickson wetlands, among the joggers and dog walkers who frequent the area. There are some additional requirements using old and new technology.
The starting coordinates are for an information sign. The QR code provides a link to information about another nearby urban feature in ABCDEFG St, Somewhere Else. Not sure whether this is a printing error, but we're going to use it for this cache!
In any case, determine the location of WP1 as
S35 (b+c).(a-b-g) (c-d) (f-a) E149 (e-f-a).(d-a-b) (f-g) (b-c+e)
At WP1, a small tree, take magnetic compass bearings to features visible from here.
From WP1 to the beacon at the top of Mt Ainslie, the compass bearing is JKL0.
From WP1 to the nearest corner of the wetlands lookout / outlet structure, the compass bearing is PQR0.
From WP1 to the nearest light pole, the compass bearing is STU0.
Determine the location of WP2 as
S35 (b+c).(S) (J+P) (2P) E149 (e-f-a).(f-J) (a+P+J+g) (S+P+a)
At WP2 you should see some structures.
X is the number of water outlets to Sullivans Creek
Y is the number of large concrete in-ground water tanks on the other side
GZ is
S35 (b+c).(X-Y-J) (g) (X+P+J) E149 (e-f-a).(X+a) (Y) (f)
Enjoy Dickson Wetlands!
