? Stream flows were very low, despite 100 mm of rain 9 to 12 days previously. ? As expected at such low flows, dissolved oxygen, conductivity (salinity) and phosphorus results ranged from Fair to Degraded. ? Low variety and abundance of invertebrates also indicated poor stream condition. ? Scotchmans Creek was more degraded than Valley Creek, despite having much greater flow. ? There was little or no flow apparent in the wetlands (at the outlet pits of the upper and lower ponds), although Scotchmans Creek was flowing above and below the wetlands.
