NR 328.38(1) (1)Identification of ecoregions and urban areas. Ecoregions and urban areas identified in Figure 1 are based on scientific literature characterizing the ecology of Wisconsin streams (Lyons et al. 1996; Wang et al.1997; Lyons et al. 2001; Wang et al. 2003; and Weigel et al. 2006), Omernik 1987, and Omernik et al. 2000. The department shall provide applicants with maps and internet-based location tools for the purpose of determining ecoregion and urban watersheds.

NR 328.38(2) (2)Calculation of stream bank erosion intensity index. The department shall provide applicants with worksheets and internet-based computer software for the purpose of calculating the bank erosion potential index (BEPI). When the department or applicants assess erosion at the bank stabilization site, they shall apply methods outlined in Table 1 to calculate a bank erosion potential index (BEPI) score. For each continuous treatment site of 300 feet or less, applicants shall submit at least one BEPI assessment. For continuous treatments greater than 300 feet, applicants shall conduct and submit BEPI assessments at 150 foot intervals along the treatment site.
Table 1
Bank Erosion Potential Index (Bepi) Score Worksheet
Applicants and department staff shall use this worksheet to calculate erosion intensity pursuant to s. NR 328.38 (2). - See PDF for table PDF
NR 328.38 Note Note: Table 1 is adapted from Rosgen, David L. “A Practical Method of Computing Streambank Erosion Rate", Wildland Hydrology Inc., Pagosa Springs, CO, 10 pp.
1. Ordinary High Water Mark (OHWM) means the point on the bank or shore up to which the presence and action of water is so continuous as to leave a distinct mark either by erosion, destruction of terrestrial vegetation or other easily recognizable characteristics. If bank material is composed of bedrock outcrop, stop with the BEPI assessment at this point; the reported total BEPI score is assumed equal to 0.
2. Maximum bank height means the vertical measure (feet) from the bank toe to the top of the bank lip, irrespective of changes in the water level. Bank toe is the inflection or bending point between the bank face and stream bed.
3. To measure the bank slope (degrees), the rise and run must be measured from the bank toe to the top of the bank lip. With your measure tape or stick, place the end firmly on the bank toe, parallel to the bank face and measure up to the bank lip to find the rise or max bank height. Subsequently, measure the run from the bank toe to the bank lip. From these measures, one should be able to calculate the bank slope with the formula `bank slope= inverse tangent (rise/run)'. Additionally, the BEPI Calculator is available on the Department's website This website automatically calculates the bank slope and BEPI score after inputting fields for bank materials, structures upstream, OHWM height, max bank height, distance to bank face, bank layering/stratification, bank vegetation, and thalweg location.
4. Stratification or bank layering means soils consisting of alternating layers of varying soils or textures.
5. Bank vegetation is the type and abundance of vegetation occurring between the ordinary high water mark (OHWM) and the bank lip. To assess the abundance of vegetation on the targeted bank, apply a 10 foot wide window of assessment from the OHWM to the top of the bank. The following percentages are assigned for the categories: bare soil visible over less than 30% of the surface area=dense vegetation; bare soil visible across 30-59% of the surface area= clumps of vegetation; bare soil visible across 60-90% of the surface area = vegetation sparse; bare soil visible across > 90% of the surface area = vegetation absent. Root wads, tree falls, and snags on the bank are considered in this assessment, because of their influence on thalweg, sediment transport, scour, and bank protection. After assessing the percentage of bare soil in the `box', record its associated point value.
6. Thalweg means the deepest part of the channel or the location of fastest current. To find the thalweg, the channel must be divided into thirds. The applicant needs to perform one or a mixture of tests for the three segments in determining its location. The following tests are suggested: float an object such as an orange peel down the stream to find the segment of fastest current, find the segment with the bubble line visible at the water's surface, or find the deepest part of the channel, if safe. After locating the thalweg, record its proximity to the tested bank, adjacent (closest), center, or opposite (furthest) and record its associated point value.
NR 328.38(3) (3)Bank edge recession measurements. Methods of measuring bank edge recession shall include all of the following: establishment of a physical measurement reference line between at least 2 headstakes; date-imbedded photographs showing the initial installation of the reference line and headstakes; reference distance measures to the bank lip shall be reported on department supplied forms; and time between separate measurements shall equal or exceed 3 months during the open-water season.
