DescriptionOxygen depletion in rivers and streams is among the top 5 impairment types most frequently cited in state water quality reports in the U.S., especially in the South. Such impairments require the development of Total Maximum Daily Loads (TMDLs) or other strategies to ameliorate low dissolved oxygen (DO) levels or high biochemical oxygen demand (BOD). TMDLs allocated to forested waterways in some states have called for reductions in BOD through appropriate harvesting and site preparation techniques. Specific silvicultural prescriptions for riparian areas following best management practice (BMP) guidelines can help mitigate elevated BOD levels in streams. However, recent surveys and research on streams in the South, including unimpaired waterbodies, have encountered naturally-occurring low DO concentrations that are already below state water quality standards (Ice and Sugden 2003).
