奥斯汀湖10月12日起放水降位约10英尺 码头维修窗口开启至11月底
奥斯汀市政府与下科罗拉多河管理局（LCRA）宣布，奥斯汀湖（Lake Austin）计划性放水已于10月12日正式启动，将持续至11月30日。期间湖面水位将下降约10英尺，最终降至约481.8至482.8英尺的目标区间，水位预计以每天约1英尺的速度下降，约三周内到位。
市府表示，这次放水是定期维护安排，目的是为沿岸业主提供维修私人码头、驳岸和船坞的窗口期；市消防部门和公园部门也将利用低水位期开展设施维护。部分维修作业需要事先取得许可，市府为船坞小修项目设置了专门的豁免申请通道，业主可通过市政网站查询。
放水期间，湖区的公共船下水坡道将关闭，艾玛·朗公园（Emma Long Park）水域禁止游泳。市府提醒沿岸居民提前固定船只和浮筒设施，并注意裸露湖床的淤泥风险，勿让儿童和宠物靠近。
奥斯汀湖是科罗拉多河上由汤姆·米勒大坝拦蓄形成的水库，兼具供水、发电和休闲功能。上一次类似规模的放水维护已是数年前。市府称，水位将于12月初逐步恢复正常。
这类放水维护通常每隔数年安排一次，为的是把沿岸居民需要低水位才能完成的维修集中在一个窗口期处理。市府建议业主提前规划施工时间、备齐材料，以免错过窗口；从事码头施工的承包商也提醒，小型维修应尽早预约，窗口期后段通常排期紧张。

Lake Austin Drawdown Begins Oct. 12: Water to Drop About 10 Feet Through Nov. 30 for Dock Repairs
The City of Austin and the Lower Colorado River Authority (LCRA) announced that the planned Lake Austin drawdown officially began on Oct. 12 and will run through Nov. 30. The lake level will drop by roughly 10 feet, to a target range of about 481.8 to 482.8 feet, falling at roughly one foot per day and reaching the target in about three weeks.
Officials said the periodic drawdown gives shoreline property owners a window to repair private docks, bulkheads and boathouses, while the city's fire and parks departments carry out their own maintenance. Some repair work requires permits, and the city has set up a dedicated waiver application for minor dock repairs, with details on the city website.
During the drawdown, public boat ramps on the lake will be closed, and swimming is prohibited at Emma Long Park. The city advises shoreline residents to secure boats and floating structures in advance and warns of mud hazards on the exposed lakebed, urging people to keep children and pets away.
Lake Austin, a reservoir on the Colorado River impounded by Tom Miller Dam, serves water-supply, power-generation and recreation functions. A drawdown of this scale was last carried out several years ago; water levels are expected to return to normal in early December.
Drawdowns of this kind are scheduled every few years so that repairs requiring low water can be concentrated in a single window. The city advises owners to plan work and materials in advance so as not to miss it; dock contractors likewise urge early booking for small jobs, as schedules typically tighten late in the window.
