There was always a good chance that flow would develop slowly and that erosion would take time to initiate.&nbsp; Flow needs to reach &gt;2,500 cubic feet per second to equilibriate the lake level even at the current rate of inflow.&nbsp; The river discharge will more than double over the next month, putting further stress on the spillway.&nbsp; The best image illustrating the latent threat at this site is this one, also taken yesterday:<\/p>\n<div class=\"separator\" style=\"clear: both;text-align: center\"><a href=\"https:\/\/blogs.agu.org\/landslideblog\/files\/2010\/10\/10_05-spillway-flow-2.jpg\"><img loading=\"lazy\" decoding=\"async\" border=\"0\" height=\"480\" src=\"https:\/\/blogs.agu.org\/landslideblog\/files\/2010\/10\/10_05-spillway-flow-2.jpg\" width=\"640\" \/><\/a><\/div>\n<p>At the moment this is very reminiscent of the early stages of flow at Tangjiashan:<\/p>\n<div class=\"separator\" style=\"clear: both;text-align: center\"><a href=\"https:\/\/blogs.agu.org\/landslideblog\/files\/2010\/10\/08_06-tangjiashan-10.jpg\"><img loading=\"lazy\" decoding=\"async\" border=\"0\" height=\"640\" src=\"https:\/\/blogs.agu.org\/landslideblog\/files\/2010\/10\/08_06-tangjiashan-10.jpg\" width=\"387\" \/><\/a><\/div>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content -->","protected":false},"excerpt":{"rendered":"<p>Flow through the spillway continues to increase slowly.&nbsp;
