computer operated to open up one by one when water gets to a certain level, although it would only be in times of flood that all 18 gates would open. The barrage also incorporates a fish ladder to allow fish to get from the tidal water to the fresh water and vice versa. The construction of the barrage had a significant impact on native fish species as it prevented them from accessing breeding, spawning and nursery habitats. Although a fish passage was incorporated into the barrage during its construction, it wasn't very effective as it was designed for North American salmon. A new vertical fish passage was installed in 1996 which was an improvement on the original but it was only effective for eight hours each day during the high tides. A new more effective $500,000 fish ladder was installed at the barrage in 2016 replacing the one which was installed in 1996. Crocodiles are regularly spotted near the barrage. Fishing and swimming is prohibited within 400 metres downstream and within 400 metres upstream from the barrage. The site is monitored by closed circuit television for public safety and security. Illegal fishing near the barrage has been an ongoing issue for Fitzroy River Water. Despite the notion that the barrage would provide Rockhampton with a bountiful supply of water negating the need for Rockhampton residents to pay for the water, Rockhampton City Council controversially introduced water meters in 2005. Community open days at the barrage were held in 2011, 2014 and 2017 as part of National Water Week. The 2017 event attracted approximately 5,000 people. In 2019, it was reported Rockhampton Regional Council were preparing to hold celebrations in 2020 to mark the 50th anniversary since the official opening of the Fitzroy River Barrage but the COVID-19 pandemic prevented this from going ahead.
