The lake is part of a greater irrigation and aqueduct system built in the 1960s in Saskatchewan and was named after Indi, an unincorporated railway point nearby on the Canadian National Railway (CNR).<ref>{{cite web |title=Indi|url=https://toponymes.rncan.gc.ca/search-place-names/unique/HAATR|website=Canadian Geographical Names Database |publisher=Government of Canada |access-date=18 July 2025}}</ref>
The lake sits in the Blackstrap Coulee,<ref>{{cite web |title=Blackstrap Coulee|url=https://toponymes.rncan.gc.ca/search-place-names/unique/HAEBR|website=Canadian Geographical Names Database |publisher=Government of Canada |access-date=18 July 2025}}</ref> which is {{convert|25|km}} long and consists of two lakes, Blackstrap and Indi. The lakes are connected by an aqueduct system that begins at Lake Diefenbaker. Indi Lake is the shallower of the two lakes and has a more marsh-like bottom; both lake beds were farmed during dry seasons prior the dams being constructed.<ref>{{cite web |url =http://www.bsc-eoc.org/iba/site.jsp?siteID=SK078 |title =Blackstrap Coulee - Dundurn, Saskatchewan |publisher =Bird Studies Canada |accessdate =2011-03-06 |archive-url =https://web.archive.org/web/20110725104019/http://www.bsc-eoc.org/iba/site.jsp?siteID=SK078 |archive-date =2011-07-25 |url-status =dead }}</ref> A short creek at the south end of the lake connects it to Brightwater Creek.

The dams at Indi and Blackstrap lake and the channel that brings water from Indi to Blackstrap Lake are part of a much larger system that brings water from the South Saskatchewan River through a series of aqueducts to the area. The aqueduct system starts at the Gardiner Dam at Lake Diefenbaker and supplies water downstream to other reservoirs as well, including Brightwater, Broderick, and Bradwell Reservoirs.
