The state doesn't regulate small dams like the one at Stephens Lake in Columbia, one of 4,000 unregulated dams in Missouri.
Blunt and the DNR support plans to warn people downstream from dams about threats. The governor and department also recommend eliminating exemptions for farm dams, federally-regulated dams, and conservation or irrigation dams.
DNR's recommended those changes to Blunt after the Taum Sauk Reservoir ruptured last December. But, a state lawmaker from that area worries budget cuts won't let DNR hire enough engineers to inspect the additional dams.
"When you talk about doing more inspecting, and closer scrutiny, then you're going to be talking about more employees," explained Rep. J.C. Kuessner of Eminence.
The federal Energy Regulation Commission oversees the Taum Sauk Reservoir, but the rupture raised questions about state-regulated dams in Missouri.
