Summary

To show the location of the freshwater sources on Chuuk.

Description

This dataset shows the location of the freshwater sources recorded on the topographic map of Chuuk, 1:25,000 scale, published by the U.S. Geological Survey (2001). The dataset distinguishes between springs and wells, as shown on the original map. The wells are mostly shallow, dug wells, but may also include deeper, drilled wells on Weno and other islands. The data layer was created by Island Research & Education Initiative (iREi) (2020) by manually digitizing features from the USGS topographic map. The locations are approximate and may include features that no longer exist. It should be noted that Chuuk Lagoon has no karst terrain on high islands, so all groundwater there issues from volcanic aquifers.
