I agree with Razorback. There is zero, nada, none, no hydrilla in Lake Tyler East or the old lake. When I purchased property in 2009 it was everywhere in my location. Recently I asked a neighbor what happened to it as it was here before I built my house. He happily told me he, himself made a call to the City of Tyler to get rid of it. Gentlemen and ladies, at Lake Tyler there is a perpetual war on hydrilla. It will never resurface in this lake.
There is some green grassy stuff in many places but it barely holds fish.
