Note: The boundaries of the watershed area will be based on factors including the amount of funds available, the management needs identified in the TMDL and the management strategy set forth in the TMDL implementation plan.
Note: The Wisconsin Buffer Initiative finds that watersheds in this size range provide the best opportunity for cost-effectively solving surface water resource problems in threatened or partially degraded waters using agricultural nonpoint source pollution control best management practices. The Wisconsin Buffer Initiative is published by the University of Wisconsin College of Agricultural and Life Sciences. Copies are on file with the department and the secretary of state.

TMDL implementation projects contribute to the cost-effective removal of surface waters from the state's impaired waters list in a way that is consistent with TMDLs and TMDL implementation plans. The degree to which compliance with state performance standards and prohibitions is needed to address these impairments will vary by waterbody.
Non-TMDL control projects improve degraded surface waters (including surface waters on the section 303 (d) list that do not yet have TMDLs or TMDL implementation plans), to improve degraded groundwater and to protect threatened and high quality surface and ground waters from degradation. These projects achieve their goals by implementing state performance standards and prohibitions.
Large-scale projects and small-scale TMDL implementation projects set control priorities based on a watershed plan or other process to identify needs and cost-effective strategies. Small-scale non-TMDL control projects implement state performance standards and prohibitions wherever they may occur, leading to a general reduction in nonpoint source pollution.
