Brookville Lake at Brookville is held back by Brookville Dam , an earthfill embankment, holding the pool back by sheer mass and an impervious core rather than by the strength of concrete , standing 181 ft high and running 2,800 ft along its crest , built across EAST FORK OF WHITEWATER RIVER in Franklin County , near BROOKVILLE . It was completed in 1974 , and is owned by USACE - Louisville District , to a design credited to CELRL.
Its recorded primary purpose is flood risk reduction — the pool is drawn down between storms so there is empty space waiting for the next flood, which is why this level can fall in dry weather and climb sharply after rain. Its spillway is ungated: once the pool reaches the crest, water leaves on its own and the operator cannot hold it back. NID classes it high hazard potential. That describes what a failure would cost downstream — loss of life would be expected — and says nothing about how likely a failure is, or what condition the dam is in.

Cagles Mill Lake is held back by Cagles Mill Dam , a rockfill embankment — quarried rock placed in compacted layers around a sealing core , standing 150 ft high and running 950 ft along its crest , built across MILL CREEK in Putnam County , near BOWLING GREEN . It was completed in 1953 , and is owned by USACE - Louisville District , to a design credited to CELRL.

Cm Harden Lake is held back by Cecil M. Harden Dam , an earthfill embankment, holding the pool back by sheer mass and an impervious core rather than by the strength of concrete , standing 119 ft high and running 1,860 ft along its crest , built across RACCOON CREEK in Parke County , near MANSFIELD . It was completed in 1960 , and is owned by USACE - Louisville District , to a design credited to CELRL.

Eagle Creek Reservoir is held back by Eagle Creek Reservoir Dam , an earthfill embankment, holding the pool back by sheer mass and an impervious core rather than by the strength of concrete , standing 92 ft high and running 5,100 ft along its crest , built across EAGLE CREEK in Marion County . It was completed in 1967 , and is owned by INDIANAPOLIS DEPARTMENT OF PUBLIC WORKS .
Its recorded primary purpose is flood risk reduction — the pool is drawn down between storms so there is empty space waiting for the next flood, which is why this level can fall in dry weather and climb sharply after rain. Its spillway is gated, so the operator can hold the pool above the spillway crest and meter what leaves. NID classes it high hazard potential. That describes what a failure would cost downstream — loss of life would be expected — and says nothing about how likely a failure is, or what condition the dam is in. Its most recent condition assessment was poor — a deficiency was recognised that needs attention. National Inventory of Dams record IN00084 — U.S. Army Corps of Engineers, public domain.

Geist Reservoir at Indianapolis is held back by Geist Reservoir Dam , standing 44 ft high and running 1,400 ft along its crest , built across FALL CREEK in Marion County . It was completed in 1944 .
Its recorded primary purpose is water supply — delivering water to its customers comes first, so drawdown here follows demand as much as it follows rainfall. Its spillway is ungated: once the pool reaches the crest, water leaves on its own and the operator cannot hold it back. NID classes it high hazard potential. That describes what a failure would cost downstream — loss of life would be expected — and says nothing about how likely a failure is, or what condition the dam is in. Its most recent condition assessment was fair: sound under normal loading, though a rare or extreme event could expose a deficiency.
