recommended by the Mooresville Regional Office that the date range for the weather data should
be most current and should include the years 2018 or 2020 (wettest years on record for the
Mecklenburg County area as per the recent Annual Drought meeting of the Catawba-Wateree
Drought Management Advisory Group) [15A NCAC 02T .0604(c)(3)].
