It is located just east of the northern tip of Grosse Ile (Hennepin Point) and about 500 feet (152 m) west of the Canada–United States border. The island is part of Grosse Ile Township in Wayne County, Michigan.<ref>{{cite web| last=Buttle and Tuttle Ltd| url=http://www.placenames.com/us/p1617049/| date=2000–2008| title=Wayne County islands place names: Mamajuda Island| access-date=December 25, 2009| url-status=dead| archive-url=https://web.archive.org/web/20070317182024/http://www.placenames.com/us/p1617049/| archive-date=March 17, 2007}}</ref> It is the smallest of all charted islands in the Detroit River.
The former 30-acre (12 ha) island has since been lost to erosion. Only a very small portion of it, consisting of a few boulders, appears above water during times of low water levels.<ref name="LHOS">{{cite web |last=Biggs |first=Jerry |date=Oct 2000 |title=Mission to Mama |url=http://www.lighthousedepot.com/lite_digest.asp?action=get_article&sk=0873&bhcd2=1261722417 |access-date=December 25, 2009 |archive-url=https://web.archive.org/web/20110614090844/http://www.lighthousedepot.com/lite_digest.asp?action=get_article&sk=0873&bhcd2=1261722417 |archive-date=14 June 2011 |url-status=dead}}</ref> Because of that, the island has no definitive size and cannot be used for any purposes.

The shoal is about 3–8 feet (0.9–2.4 m) beneath the surface and runs all the way to Grassy Island.<ref>{{cite web|last= Hamilton| first= Sam D.| url=http://www.fws.gov/policy/library/2001/01fr43898b.pdf| date=9 Aug 2001| title= Fish and Wildlife Service: Federal Register| access-date= December 25, 2009}}</ref> The area, including Mamajuda Island, has since become part of the Detroit River International Wildlife Refuge.<ref>{{cite web| last= U.S Environmental Protection Agency| url= http://www.epa.gov/med/grosseile_site/indicators/refuge-map.html| archive-url= https://web.archive.org/web/20120505195118/http://www.epa.gov/med/grosseile_site/indicators/refuge-map.html| url-status= dead| archive-date= May 5, 2012| year= 2009| title= Detroit River-Western Lake Erie Basin Indicator Project| access-date= December 25, 2009}}</ref>
The island was originally named after an American Indian woman who regularly camped on the island during fishing season.<ref name=LHOS/> In 1849, the Mama Juda Lighthouse was built on the island, and the lighthouse keeper and his family were the island's only inhabitants. The lighthouse itself was rebuilt in 1866.<ref>{{cite web| last= About the Great Lakes| url= http://www.abouthegreatlakes.com/lighthouses.htm| year= 2009| title= Lighthouse Design and Construction| access-date= December 25, 2009| archive-url= https://web.archive.org/web/20091106143843/http://www.abouthegreatlakes.com/lighthouses.htm| archive-date= November 6, 2009| url-status= dead}}</ref> However, the loose composition of the island was subject to slow erosion that eventually washed away the lighthouse in 1950. The whole island itself disappeared by 1960, and only a few boulders from the former island periodically protrude above the surface.<ref name=LHOS/> However, because of the underlying shoal, the area can pose a hazard for boating in the area, especially for large lake freighters that regularly travel within close proximity. {{clear left}}
