Flooding in Lincolnshire caused more damage in the area because waterways and ditches had not been properly maintained, it has been claimed.
Farmers have lost crops and livestock in the floods
The Country Land and Business Association, which represents many farmers, said a lack of funding had led to drainage becoming inadequate.
Agricultural land across the county has been inundated and crops have suffered.
But the Environment Agency said that while it welcomed more funding, nothing could have handled recent rainfall.
Chairman of the Country Land and Business Association Robin Battle said: "These channels are designed to take the water away but if they are clogged with silt and weeds then the water can't flow.
"It is up to the government to provide more funding to the Environment Agency because the agency can only work with what they are given."
Ian Russell, from the agency, said that while nothing could have prevented the recent floods, more money would help in the future
"The more funding we get the more we can do. We have been focusing on making the best bids we can for funding.
"We have also been looking at efficiency, to make the best use of the money we do get."
