North Perth and Milverton fire stations will join the search for a missing 10 year old who fell into the riverbanks south of Mitchell as efforts enter day 4.
Search and rescue crews have worked around the clock since Sunday when the girl was first reported missing with each day of searches being suspended due to darkness.
Crews were setup on Tuesday on Perth Road 160 as an OPP helicopter flew over the river and crews scanned the water.
While officials have said they appreciate the offer of assistance from citizens they continue to advise residents to stay clear of the waters edge.
