Saint Kitts and Nevis

Water resources

Surface water and groundwater resources

Annual average surface water resources are estimated at 3.6 million m3 and groundwater resources at 20 million m3. Considering no overlap between surface water and groundwater resources, the total renewable water resources are estimated at 23.6 million m3 (Table 2).

Most of the rivers of the country no longer have year-round flows. Small rivers flow from the mountain ranges in the wet season, drying up partially or completely in the dry season. Two important seasonal rivers are the Wingfield and Cayon rivers on Saint Kitts, which during the wet seasons flow to the Caribbean Sea.

The main groundwater supply is from a coastal aquifer, with seven groundwater basins. The estimated safe yield is approximately 38 million litres or 38 000 m3 per day. This figure, however, is now under discussion since the groundwater aquifers are being impacted on by sea level rise and will eventually be negatively impacted by saline intrusion due to climate change.

The Great Salt Pond on Saint Kitts is the largest lake in the country. Some small dams and structures have been made, with a total capacity of about 32 000 m3.
