Cruz Water Catchment

The Cruz Water Catchment, also known historically as Finona's Water Catchment, is a historic private water supply structure in the United States territory of Guam. It is located south of Guam Highway 9 in the village of Potts Junction in the central northern part of the island. It is a circular concrete structure 3.74 m in diameter, and is 2.55 m in height, of which 0.87 m is exposed above ground level. Its estimated capacity is just over 17000 L. It was built, according to local oral history, about 1920, and was used to capture rainfall from a nearby house that was destroyed by Typhoon Karen in 1962. The catchment was used to provide water to as many as seven local households, making possible year-round living in an area otherwise lacking fresh water.

The structure was listed on the National Register of Historic Places in 1994.
