"Here's the last few days, you can see they tried to release extra I assume because of the forecast of tropical storm Bill." So they want Whitney to go over the dam??
You're talking like I work there..... Pk won't hold a whole lot extra like say grapevine, why I don't know, but they try to stay at 999.
Here's why from what they say:
"Uncontrolled Spillway. The fourth method to release water from the dam is to use the
uncontrolled spillway. The uncontrolled spillway is the large flat area on the south side of the
dam cut into rock at elevation 1000-ft. It is only used during floods larger than can be released
by the nine spillway gates. In the history of Morris Sheppard, such a flood has not occurred, but the facilities are there if needed.For the uncontrolled spillway to be used, all the
spillway gates would be open, and the floodwater would continue rising above elevation
1000-ft, at which time the lake would begin discharging over the uncontrolled spillway."
Talk about a flood downstream....
