Flag Lake is a 664-acre lake located on Barksdale Airforce Base near Bossier City, Louisiana. The lake is relatively shallow, averaging less than four feet deep, and serves as a valuable aquatic resource to the base and the surrounding communities by providing excellent fish and wildlife habitat, as well as important recreational opportunities in the form of fishing, waterfowl hunting and wildlife viewing. Historically, Flag Lake has suffered from the excessive growth of a variety of plant species, but most notably, invasive hydrilla (Hydrilla verticillata), American lotus (Nelumbo lutea) and water hyacinth (Eichhornia crassipes). In recent years, however, giant salvinia (Salvinia molesta) has dominated the plant assemblage, reaching problematic conditions in 2017 with an estimated 500 acres of water covered in this invasive aquatic plant. To combat this invasive species, SOLitude employed a volumetric management approach that was fairly experimental for an infestation of this magnitude.
