			The Department of Water Resources established a network of 38 groundwater level and quality monitoring boreholes in 2014, during the National Water Sector Reform Project (NWSRP) funded by the African Development Bank. Monitoring boreholes were initially fitted with automatic groundwater level loggers, but some have failed since (IGRAC 2020). The network is distributed across Gambia. Recorded groundwater level measurements are downloaded every 3 months, and data is stored in the GeOdin database in the Department of Water Resources.
