Boomanoomana wet­land gets a big taste of spring

Southern Riverina news - - RURAL OUTLOOK -

The Boomanoomana wet­land will get a taste of spring wa­ter this month with the de­liv­ery of up to 400 me­gal­itres through the Mur­ray Ir­ri­ga­tion net­work.

Mur­ray Ir­ri­ga­tion and the NSW Of­fice of En­vi­ron­ment and Her­itage (OEH) be­gan wa­ter­ing the Boomanoomana wet­land near Mul­wala ear­lier this month.

The de­liv­ery will in­un­date 72 hectares of wet­land to main­tain im­por­tant na­tive wet­land flora in­clud­ing river red gum, mil­foil and wa­ter rib­bons – all im­por­tant habi­tat for wildlife.

The Boomanoomana wet­land wa­ter­ing co­in­cides with the de­liv­ery of wa­ter for the en­vi­ron­ment to the Tup­pal Creek via the Mur­ray Ir­ri­ga­tion sys­tem which started in Au­gust. At the same time, wa­ter­ing of seven pri­vate lo­cal wet­lands has be­gun and will con­tinue over the com­ing weeks to pro­mote south­ern bell frog breed­ing.

Th­ese wa­ter­ing ini­tia­tives are part of a for­mal agree­ment be­tween Mur­ray Ir­ri­ga­tion and OEH signed last year to de­liver wa­ter for the en­vi­ron­ment through lo­cal ir­ri­ga­tion in­fra­struc­ture.

‘‘This part­ner­ship be­tween Mur­ray Ir­ri­ga­tion and NSW Of­fice of En­vi­ron­ment and Her­itage has ben­e­fits all round,’’ Mur­ray Ir­ri­ga­tion En­vi­ron­men­tal Wa­ter Co­or­di­na­tor Keith Thomp­son said.

‘‘En­vi­ron­men­tal ob­jec­tives are be­ing met and Mur­ray Ir­ri­ga­tion is at­tract­ing more wa­ter use within its sys­tem.

‘‘It makes a lot of sense util­is­ing ex­ist­ing in­fra­struc­ture to de­liver wa­ter for the en­vi­ron­ment, es­pe­cially con­sid­er­ing that Mur­ray Ir­ri­ga­tion has the abil­ity to de­liver wa­ter strate­gi­cally us­ing a grav­ity-fed sys­tem.’’

The agree­ment be­tween Mur­ray Ir­ri­ga­tion and OEH builds on a pre­vi­ous ar­range­ment to de­liver wa­ter for the en­vi­ron­ment to wet­lands since 2001.

This tar­geted wa­ter­ing al­lows wa­ter man­agers to get wa­ter to key ar­eas while mit­i­gat­ing neg­a­tive third-party im­pacts.

As part of the cur­rent agree­ment, OEH pays the same stan­dard wa­ter de­liv­ery fees as other cus­tomers plus a con­veyance load­ing.

‘‘This deal has ab­so­lutely no neg­a­tive im­pact on our ir­ri­ga­tor cus­tomers,’’ Mr Thomp­son said.

‘‘Wa­ter for the en­vi­ron­ment is done strate­gi­cally. We man­age the sys­tem to en­sure there are no flow share im­pacts on ir­ri­ga­tors.

‘‘This is about kick­ing en­vi­ron­men­tal goals, while also de­liv­er­ing ex­tra wa­ter through the sys­tem, and in turn, im­prov­ing the long-term sus­tain­abil­ity of Mur­ray Ir­ri­ga­tion’s sys­tem.’’
