Subject: Streams Matrix For Use In CRP Eligibility Determinations

The attached "Stream Matrix for Use in CRP Eligibility Determinations" has been modified from the original matrix issued with CRP Technical Guidance Number 28 (February 15, 2001). This matrix replaces the previously issued matrix and will be utilized from this date on.

The "flow duration" for "seasonal" streams has been modified to include the Division of Water Resources stream definition drainage criteria. This addition will allow more flexibility to implement filter strips/riparian buffers on central and western Kansas drainages where shaping of a waterway is not feasible. As before, this guidance should always be used in conjunction with a field visit to document actual on-site conditions and feasibility of the practice to be applied.

Keep in mind that waterways (CP8A) should be applied to address water conveyance issues. This would apply to areas where it is feasible to stabilize a drainage ditch by shaping a waterway, meeting 2-CRP size requirements, to allow for conveyance of channelized flow. Filter Strips/Riparian Buffers (CP21 & CP22) are applicable to areas where water quality issues can be addressed by overland sheet flow through the filter strip/riparian buffer practice. These practices would be applicable where sheet runoff water would pass through the established practice and be filtered prior to entering a defined drainage channel.

All information utilized to determine practice applicability, pertaining to this matrix and observed in the on-site field visit, will be provided to the Farm Service Agency (FSA) County Operating Committee (COC) and maintained in the producer case file.

Area office assistance is available for stream eligibility determinations.
