Creepy.. that 'thin' wall and those masses of water
Great shot Ian. Is this taken recently?Greetings Berend
Like eggshell Fried, designed for maximum strength and less material. A much higher concrete-arch structure, Tumut Pond Dam were built in the Snowy Mountains Scheme using this engineering principle before Moogerah was built. Recent slow structural deformation testing has shown no significant movement of Tumut Pond wall. The concave structure means that most of the load is transferred to the abutments.
Hope the reassurance is all you and the folks downstream ever need.
Yes Berend, this is quite recent, post-flood, and as you have seen the floods have passed for now leaving the lake filled above full supply level, hence the overflowing spillway. This sub-catchment of the Brisbane River certainly discharged a significant portion of the floodwaters that inundated Ipswich, then flowed into the Brisbane River.
