Anyone See the Sluice Gates Open in 1978?

[MickinMO]

Phil's post a few weeks ago about DO levels and how Table Rock's water profile works during the year to affect fishing renewed my childhood interest in how the dam operates. Never will forget the dam tour as a kid. If you ever have time to burn, the attached is an in-depth study released by DNR I came across.  Who's for opening the sluice gates again? Based on pictures of dam construction and how they are described in the attached report, those must be tubes that are at the base of the middle of the spillway and allowed the white river to flow and keep Table Rock from filling too fast as dam construction moved higher and before the powerhouse was completed. Early construction photos show current coming from underneath the rising spillway and nowhere near the unfinished powerhouse tailrace and penstocks. Apparently they opened the sluice gates in 1978 to try and help the DO situation. Was deemed too dangerous as water shot 100ft into the air and travelled 200ft downstream. They tried the same thing at Norfolk and the physics proved too risky.
