MangaJiao River: Martina Bridge Erosion.—Work carried out consisted of two small piled deflection groynes on left bank above bridge approach., and heavy crated stone and tethered weighted tree protection for a length of 5 chains on right bank below bluff, backed by an earth stop-bank 12 chains in length and 6 ft. in height. 45 per cent, of the final proposals has been completed. Mangatainoka River. —Milne's Erosion: A small crated-stone deflection groyne has been constructed and small channel improvements affected to protect access and to re-establish old channel. Allen's Erosion: A short shingle-end tree groyne with two small downstream crated-istone groynes were constructed to prevent access road being outflanked and to protect a power-line. O'Brien's Erosion: A small cut off bank was constructed to prevent overflow and flooding at dairy factory. The major portion of this work, consisting of a large diversion cut 29 chains in length, has been deferred. RuamaJumga River: Te Ore Ore River Board Length.—The proposals covered work consisting mainly of earth stop-banking and bank-protection of crated stone, and willow mattress thatching, protected by stock fencing, and work as follows was carried out:— Willow Thatching and Stone Gabions: No. 8 (Savages), f chain; No. 9 (Moores), 3 chains; No. 10 (Ewingtons and Wyeths), 10 chains; No. 12 (Burlings No. 1), 2 chains. Stop-banking: No. 13 (Coles and Coopers), 59 chains; No. 14 (Coopers to Sewer Outfall), 22 chains. Otaraia Peninsula, Kahautara River Board: A new stop-bank, 18 chains in length, and 36 ft. of 9 in. pipe culvert have been completed.

Tauiherenikau River Diversion.—A survey and complete scheme has been prepared to divert this river by a shorter course into Lake Wairarapa. This will render possible the reclamation of several hundred acres of lagoon area marginal to the lake and drainage improvement and flood protection of farm lands adjoining the river. Lake Wairarapa Land Development.—Further investigation is in hand of a scheme to reclaim about 28,000 acres of lagoon and low-lying country by a major diversion of the Ruamahanga River.
