Winter drawdown possibly would help depending on your location. If the soil temperature doesn't get low enough to freeze roots, etc. it just comes back. Summer drawdowns can cause other problems such as susceptibility to turnovers/oxygen issues or over predation of prey such as bluegill. All depends on where you are and how big your lake is. Cost/Whitecap depends on what plant you have, how much (acreage), and label restrictions depending on what you use the water for.
