I live on the Lake , three days ago from the bend to 51 bridge there were hundreds of gulls and other birds gorging themselves on floating dead fish. i reached out to Brazos River Authority and TPWD this was there response :
" There was an golden alga bloom over the weekend that resulted in a fish kill incident at one area of Lake Granbury. Texas Parks and Wildlife warned us a couple of weeks ago that the conditions were ripe for golden and that samples were showing high concentrations. As of today, we have not had any recent fish kill reports. If you would like to learn more about golden algae, we have more information available on our website:

Fishing has been very tough (for me anyways) on that end . With that damn algea , its a ghost town around there. TPWD told me the recent cold, icy conditions actually help spread the golden algea. unknown how bad it will get. hopefully its a small flare up.
