Drought experts will meet this week to decide if stronger advice on water use is needed in response to record low river levels, BBC Wales has been told.On Thursday, Wales' drought liaison group will discuss whether all or parts of the country should be upgraded from normal to prolonged dry weather status.
Several rivers in north and mid Wales are classed as having notably low levels, while the Dee and Yscir are at their driest since records began in the 1970s.The Welsh government said its expert group would meet regularly to "ensure water supplies are effectively managed and the environment protected".Rainfall in Wales so far this spring has been well below average, with the country seeing 49% of the levels expected during March and April, according to the UK Centre for Ecology and Hydrology (CEH).
Though wetter weather is forecast this weekend and into next week, Catherine Sefton, senior hydrologist at the research institute, said sustained rainfall was needed."Unless we have appreciable rainfall now at the end of spring and going into the summer there will be concerns for water resources and the environment as well as impacts on agriculture with the dry soils," she said.
Mid and north Wales had a particularly dry April, with rivers such as the Conwy, Dee and Wye ranked as notably low, according to CEH's reports.
The Yscir in Powys was exceptionally low, recording just 21% of its average April flow.Sufian Ali and Atif Shahzad died after being beaten to death by the crew, their uncle said. He was informed of the circumstances surrounding their deaths by survivors.
Others died of starvation, dehydration and hypothermia.Those still alive, including the crew, had given up until they saw a much larger fishing vessel come into view. Uzair Bhat jumped into the ocean and swam towards it for help.
The coastguard instructed the vessel to take the migrant boat to Dakhla port - 60 miles away. According to the IOM, 15 dead bodies were found onboard while 35 people remain missing at sea and presumed dead.Pakistani authorities have named Gujjar as one of ten smugglers involved in the tragedy.
