About this map:
This map shows the locations of coastal springs mapped as part of a groundwater study by Jocson, J.M.U. (1998), Hydrologic model for the Yigo-Tumon and Finegayan subbasins of the Northern Guam Lens Aquifer (NGLA), Guam [MSc thesis], University of Guam, Mangilao, 95 pp. The study area spanned the coastal segment from Tumon Bay north to Falcona Beach. The original locations of springs were plotted on USGS topographic map. Flow estimation in mgd was based on visual observations. Seepage areas along the coast were also noted but are not included on this map. Further information can be found in Jocson, J. M.U. et al., (1999), Numerical Modeling and Field Investigation of Infiltration, Recharge, and Discharge in the Northern Guam Lens Aquifer (NGLA), WERI Technical Report # 88 (available from http://www.weriguam.org/reports/item/numerical-modeling-and-field-investigation-of-infiltration-recharge-and-discharge-in-the-northern-guam-lens-aquifer.html).
