Russian River Total Maximum Daily Load
Advanced Protection Management Program Areas

The Total Maximum Daily Load (TMDL) Action Plan provides information and requirements specific to owners of Onsite Waste Treatment Systems (OWTS), or septic systems, in the Russian River Watershed. Of particular importance is the definition of the geographic boundary of the Advanced Protection Management Program (APMP). The TMDL Action Plan defines the Russian River Watershed APMP boundary to include both:

  1. The area within 600 linear feet from the top of the bank in the horizontal (map) direction on either side of the entire Russian River mainstem; and
  2. The area within 600 linear feet from the top of the bank in the horizontal (map) direction on either side of any mapped waterbody in sub-watersheds where parcel densities are greater than 50 parcels per square mile.  Sub-watersheds, defined as Hydrologic Units Code 12 basin names, with parcel densities greater than 50 parcels per square mile include the following: Brooks Creek, Dutch Bill Creek, East Fork Russian River, Green Valley Creek, Lower Laguna de Santa Rosa, Lower Santa Rosa Creek, Mark West Creek, Porter Creek, Salt Hollow Creek, Upper Laguna de Santa Rosa, Upper Santa Rosa Creek, Ward Creek-Austin Creek, and Windsor Creek.

The TMDL Action Plan describes the requirements that may be applicable to any parcel that is wholly or partially within the APMP boundary, pending a decision of the Regional Water Board. To evaluate whether a given property is wholly or partially within the APMP boundary, the interactive mapping tool below has been developed which allows for a given parcel to be searched using an address or APN.
