31st Avenue Southwest
NAPLES — The local arm of the South Florida Water Management District broke ground this morning on a new weir on the Golden Gate canal.
The Big Cypress Basin is relocating an existing weir to a spot along 31st Avenue Southwest, about a mile east of Collier Boulevard.
The new weir will be automated to allow water managers more flexibility in providing flood protection in Golden Gate Estates and recharging underground drinking water supplies.
Two miles south of the existing weir, the new weir eventually will divert water south into Henderson Creek rather than into Naples Bay.
The old weir, build in the 1960s as part of the original drainage system in Golden Gate Estates, will be demolished after the new weir is operational.
Work on the new $3.6 million weir already is under way and is expected to be completed by fall 2010, basin spokeswoman Lisa Koehler said.
The new weir will mean boaters using the county’s Golden Gate boat ramp won’t be able to travel as far north in the canal as they can now.
Koehler said, though, that demolition of the old weir will give boaters north of the weir access to a longer stretch of canal.
