A consultant has found that detailed flood mapping of a northern Victorian lakes system would be complex work and very costly.
The Corop Lakes system between Bendigo and Shepparton includes towns such as Colbinabbin and Stanhope.
Flooding hit the area during the summer of 2011 and early this year, damaging crops, fences and roads.
Local authorities commissioned a flood scoping study and the results were presented to the Campaspe Shire last night.
The researchers say the region's flat terrain, creeks and irrigation infrastructure make local flood conditions very complex.
They say detailed mapping would provide no significant benefits.
Instead, it has suggested that increased community awareness and improved warnings would help to boost the level of flood resilience.
