Water quality:

Turbidity: 19NTU
pH: 6.3
Salinity: 180µS (EC)
Dissolved oxygen: 4.2mg/L 44%

Ultima Thule Creek, sampled from a pool that is non-flowing, 1 foot deep.

ACT Waterwatch says:

Heavy use translates here to raised turbidity from erosion. Still water tends to heat up, and thus hold less oxygen.

Further, oxygen gets into water by agitation; still water by definition doesn't have this going on. Expect dead fish as the summer hots up, or fish that can get by with little oxygen, like carp — neither is a pleasant prospect.
