JU~CTTON CREEK SITE The Junction Creek site was discounted in the 1960's on the grounds that it would cost considerably more than the Telegraph Station site, and did not provide a comparable storage size. Recent re-examination confirills this. However, it probably represents the best potential alternative recreation lake site on the Todd River to the Telegraph station. ( a) Hvdrology The site is two kilometres upstream site, and has a catchment area of 360 from 1:De Higley Go::cge , 'l ' square Kl ome-c.res .. If maximQ~ possible advantage were taken of the site, it might be possible to provide a surface area corr,parable to 1:.ne Telegraph Station site (say 90 hectares) Eowever, this would provide only about half the corresponding flood mitigation effect. _~.Al.ternativelYI it may be possible to achieve flood mitigation ::,..:-approaching that offered by the Telegraph Station site / but in this case the surface area would be reduced to around 50 hectares. (b) Recreation Potential "'~" ---->-~ ...
