Analyses of the groundwater l e v e l records f o r selected New Brunswick Department of Environment monitoring wells were performed. Presentation of t h i s data helps to demonstrate the behaviour of the groundwater levels over t h e i r e n t i r e length of record, through t o an h o u r l y perspective. These data are provided i n various v i s u a l formats to demonstrate how the data may be assembled and used f o r groundwater resource management. The p r e s e n t a t i o n formats i n c l u d e y e a r l y , monthly, d a i l y and hourly. Using p r e c i p i t a t i o n , temperature and r i v e r discharge data, a method i s presented t o enhance the value of the groundwater l e v el data. The method presented evaluates the response of groundwater l e v e l s t o recharge from r a i n f a l l , snowmelt and e v a p o t r a n s p i r a t i o n. From r i v e r discharge data, base flow separations were done to compare the behaviour of groundwater levels to that of the groundwater flow system of the r i v e r basin. Also, base flow recession constants were obtained, f o r the major recharge events of each year of i n t e r e s t , and a method presented f o r a p p l i c a t i o n to the p r e d i c t i o n of groundwater l e v e l s where data has been l o s t or i s missing.
