Rainfall during October had been above normal for Coromandel (120% - 149%) and ground conditions were moist to saturated. Observations relate to site locations shown in the map below. Site 1: The route intersects a recently excavated area containing standing water, estimated 0.5 m deep and 5 m wide (mounds of excavated soil were observed adjacent to the pond). A small of stand poplar and willow trees partly surround the pond. No water source or flow was observed, though a channel at one end drains excess water. Aquatic macrophytes were present within the waterbody including water pepper, spearwort, and alligator weed. Water appeared stagnant and cloudy.
