Sur­vey of dam im­pact

Tweed Daily News - - NEWS -

COUN­CIL con­sul­tants will be­gin to map aquatic habi­tat in Doon Doon Creek and the Tweed River next week to de­ter­mine how the rais­ing of Clar­rie Hall Dam may im­pact on fish and other aquatic species.

Sci­en­tists from Eco­log­i­cal will un­der­take the field re­search, both walk­ing and in ca­noes, to map crit­i­cal habi­tat fea­tures such as pools and rif­fles (rocky or shal­low parts with rough wa­ter) and de­ter­mine the num­ber of species within the im­pacted wa­ter­ways and the pop­u­la­tion of each species.

The field work will be un­der­taken for sev­eral days ev­ery sea­son dur­ing the next year, start­ing on June 18.

Prop­erty own­ers ad­join­ing Doon Doon Creek and the Tweed River down­stream of Clar­rie Hall Dam are ad­vised they may see a small team of sci­en­tists work­ing on and at the wa­ter’s edge.

The field work will con­tinue into the night, as the sci­en­tists iden­tify and count frog species.

From the field data col­lected, Eco­log­i­cal will at­tempt to iden­tify mea­sures to mit­i­gate any im­pact the dam has and, if raised, will have on the aquatic en­vi­ron­ment.
