The main issue I see with the lake level drop is what could happen to all of the reeds. Not sure if it would affect them but it could be a possibility.
I think it would HELP them... Would probably make the patches bigger in the short term cause they would grow out at the edges, happened during the drought. the edges grew out while water was lower, then it came up and they were too deep and started dying back off. but when there were reeds in that little bit deeper water... man that's my favourite. That said I still think the lake is on the low part of the cycle from the HAMMERING it took during the drought. 3 tourneys a week on it was NOT good
I think TPWD is thinking more about timeline, that lake has SHALLOW water but very little in between water. With spawn coming up you have an issue on how it might effect spawn, TPWD also probably doesn't want the complaints of all the spring skiers and fisherman who cant use the lake, or think TPWD is destroying a resource. My bet is they don't want to deal with the complaints more than anything... and then the spawn is a seconndary issue
