 GIS Alias               Full Text and Meaning
BarrierID: Unique geo-referenced identification number for each potential or actual barrier
Q1_StmOrdr: Question 1: Stream order the potential barrier is located on.
Q2LandUse: Question 2: Landuse. Proportion of intensive landuse within the sub-catchment the potential barrier is located in.
Q3Bar_DStr: Question 3: Number of potential barriers located downstream of the potential barrier in question
Q5_DisNxtB: Question 5: Distance to the next potential barrier upstream
Q4_Score: Question 4: Barriers geographic location within the sub-catchment, i.e. Distance (km) of sub-catchment upstream of the barrier as a proportion (%) of the total sub-catchment stream network (km).
Stg1_Scr: Stage 1 Score: The sum of all five questions after stage 1 of the barrier prioritisation.
Stg1_Rnk: Stage 1 Rank: Potential barriers rank after stage 1 of the prioritisation process.
Waterway: Waterway Name.
Barr_Name: Potential Barrier Name and/or Brief Barrier Description
Q6BarType: Question 6: Barrier Type (Barrier headloss).
Q7StrmCond: Question 7: Stream Condition. Riparian, bed and bank condition.
Q8FlowCond: Question 8: Stream Flow Classification. Perennial, seasonal or supplemented?
Q9HabCond: Question 9: Instream Fish Habitat Condition. Snags, pool, run, riffle, macrophytes, undercut banks?
Q10ProxEst: Question 10: Barriers proximity to estuarine habitats
Stge2_Scr: Stage 2 Score
Stge1_2_Sc: The sum of Stage 1 and Stage 2 scores
Q11_Cost: Question 11: Estimated cost of barrier remediation i.e. cost to construct fishway
Q12_ComSup: Question 12: Community & in-kind Support within the sub-catchment the barrier is located in, i.e. NRM Creek rehabilitation project or Council provide in-kind excavator
Q13Tech_V: Question 13: Technical viability. How difficult is the fishway to design, construct and maintain?
Q14_Produc: Question 14: Fisheries Productivity & Economic Benefits of providing unimpeded connectivity past the barrier
Q15Conserv: Question 15: Conservation Significance. Will improved connectivity benefit listed fish species?
Q16Transpa: Question 16:Barrier Transparency. How often are fish able to ascend past the barrier?
Stge3_Scr: Sum of all questions in stage 3.
Tot_3_Stge: Sum of all 3 stages (total score)
Final_Rnk: Barriers Priority Rank after 3 stages of the barrier prioritisation. Rank 1 = most important fish barrier in the targeted area.
Visit: Was the barrier visited (groundtruthed) in the field, Y = Yes, N= No.
