§ Mr. Wigley
To ask the Secretary of State for Wales how many reservoirs and lakes in Wales have been affected by poisonous algal blooms during 1989; how much dredging has taken place to get rid of such blooms; and what action he will take to ensure that algal blooms are effectively eliminated in future.
§ Mr. Grist
Monitoring carried out during 1989 revealed no significant algal blooms in Welsh reservoirs and therefore no dredging has been carried out. It is for the National Rivers Authority, in conjunction with Dwr Cymru, to consider what future action may be necessary in areas potentially affected by algal blooms.
