But in order to cope with the emergency situation, some restrictions have been introduced.
Right now, only the business that has a permit to take water from the river is allowed to do so.
Even those who have a permit are asked to use water sparingly and irrigation may currently only take place at night when water losses are smaller.
- It is the water judges who regulate this and they are different for different businesses, says Gustav Enander.
In Kalmar county, however, the Coast Guard discovered five businesses that watered during the day when they flew over Emån last week to check the area.
The county administration in Kalmar will now try to find out which businesses apply and contact them to inform them about the importance of limiting water withdrawal right now.

The County Administrative Board also has more tools to use.
- We can also proceed with injunctions and bans if necessary, says Gustav Enander.
Balance on a knife edge
During today's press conference, water officer Måns Lindell told the county board in Jönköping that the situation right now is like balancing on a knife edge.
- It's about balancing natural interests with water withdrawals for various activities, he explained.
With many summers with drought, there is a risk that natural values will be lost.
In the past, there has been talk of the river pearl mussel being threatened if waterways dry up.
- There it has been seen that it can burrow into the dune and survive a dry summer, but if there are several years of drought in a row, it risks disappearing, he explained at today's press conference.
Groundwater levels are currently below or well below normal throughout Småland, both in small and large reservoirs.
