Summary

Surveyors Report on WISALTS Conservation System created by J (Jack) Harvey.

Comments: In considering the flooding problems for Tammin township I suggest that grade could be installed to collect as much water as possible from the creeks carrying the surface water as well as sealing the throughflows with plastic sheeting in the creek beds and at any other points. 25,000 cubic yard dams I feel could easily be built in the grade line to utilise the water that is surplus to the soil needs during floods and storms, the exact location of any dams would need further tests to determine the best locations for holding and possible problems with salt water.

This grade line must be completed with upgraded culverts to carry the greatly increased flow of water that will occur. Cooperation of the shire will be necessary. Flyovers will be needed at various points for the farmers to gain access to their paddocks, stock etc. This bank needs to be of a large capacity to 1 metre deep or better. A large amount of cash could probably be saved if the adjoining farmers will come to the party in the east and south particularly, level banks outside the property in question would take a lot of the pressure off. However level banks of a large capacity would be necessary if no outside work is done, these could be allowed to overload into the main waterways above the grade line.

More testing of topsoil depth is called for yet. All level banks 1 metre or better, deep to cut as much water as possible off with plastic sheeting for deeper throughflows shown by arrows ↓ particularly at the top two banks up slope if a good job is done in the first two banks with plenty of blocks to clay level allowing for settling of these blocks, all the rest of the level banks would probably be alright, a metre deep with plenty of banks to a little better than clay level say 6 inches above when settling has occurred. All banks above grade line 3 metres vertical drop only, below grade not one 3 metres apart.

On the west side outside work on the boundary hill side above the boundary would be a great depth to dry out the scald area near the boundary on northwest side mainly.

I have marked a short grade line on this to dry out the area above the salt scalds draining this into the main waterway, this will need to be sealed on throughflows with plastic sheeting. Level banks on the remainder of the paddocks around the creeks should be deep with a good capacity a metre deep or better with plenty of blocks and sheeting as necessary on the higher banks. Use the higher ground to get control of the throughflows, the higher up this can be done the more control will be achieved overall.
