The periods of surplus , usage , deficit and recharge are as depicted in the tables . Surplus was experienced between January and March at the two locations with Terre Haute 's extending till April . Utilization occurred at about the same time for the two locations (April to May for Berkeley and May to June for Haute . The similarities were achieved in different ways

by the two climates . The year started at Terre Haute with the cold winter and this reduces evaporation rates . Therefore , the precipitation though smaller than Berkeley 's for the same period , was conserved in storage because of the low evaporation rates . On the contrary , high precipitation was observed at Berkeley . This is likely to be as a result of the moisture laden westerly winds form the pacific giving rise to relief rainfall (due to high altitude at Berkeley . However , this could not be adequately conserved due to the high evaporation rates . As a result , the storage was reduced to values similar to Haute 's

Further into the year at Terre Haute , spring likely brought about an increase in water utilization (by the blooming flowers and leaves . This reduced storage despite that there was a slight increase in precipitation . A similar trend also occurred at Berkeley at about the same time . However , this is as a result of reduction in precipitation and the attendant increase in evaporation at the onset of the dry season

Conclusion

The differences in climatic conditions and altitude are the major factors...
