Adopt a Park - final 2024 visit! Operation: stream clearing!

 Today we had our final visit to William Green Domain for 2024. 

We focused on the stream. Our aims were:

1. To find out more about the health of the stream by doing some tests and observing what was in there

2. To unblock the stream so the water could flow and not be blocked. 

the stream - where does it flow from and to? 

The favourite activities, by far, were seeing the eels and getting in the stream. 

Others students said... 

" I LOVED getting in the river and getting rubbish out" 

" I like wears boots and getting in the creek" 

" Pulling all those big weeds out was satisfying"

" The dragonfly was scary!" ( I thought it was very cool!) 

" I like going across the stream on the stepping stones" 

"Looking at tiny bugs in the tray was fun"

"Working out if the stream was healthy or not was interesting" 

can you spot the eel?

We conducted a number of experiments and observations to work out how healthy the stream was. 

Our findings were: 

Water temp: 20°C (fair)

Water clarity: avg of 71cm (good)

SO SMART (0=poor, 1=fair, 2=good)
smell - 1

obstruction - 1

stream bed - 0

margin/bank - 1

appearance of water - 2

rate of flow - 1

top surface - 1
overall SO SMART score: 7/14 (fair)

Macro invertebrates: found worms and damselfly larvae, note: eel spotted. (overall: fair)

pH: 7.5 (good)

Overall stream health: FAIR.
