The upper Broken Creek diverges from the Broken River downstream of Benalla at Caseys Weir and flows for 65 kilometres in a northerly direction to the Boosey Creek confluence near Katamatite Township. From Katamatite Township the Broken Creek flows in a westerly direction to the Murray River and is considered to part of the lower Broken Creek (see Lower Broken Creek and Nine Mile Creek above).
The creek and its associated floodplain and wetland habitats support intact grey box-dominated grassy woodland communities and numerous threatened species including Murray cod, brolga and Buloke.
The upper Broken Creek has been used for water supply from the Broken River for more than 100 years. It was supplied with flows from the Broken River for the Tungamah Domestic and Stock System and for irrigation supplied from the creek. In recent years, the Tungamah Domestic and Stock System has been pipelined and supplied from the Goulburn system, and the irrigation entitlements reduced by 80% as part of the Lake Mokoan Decommissioning project. As a result, the creek now has relatively low flows all year round from Caseys Weir to Waggarandal Weir (supplying irrigation entitlements) and is ephemeral between Waggarandal Weir and Katamatite, with short duration fresh/high flow events occurring in response to catchment rainfall.
An environmental flows study for the Broken Creek was completed in 2007. The study developed priority watering actions for all three reaches of the upper Broken Creek. The key priority watering action is the delivery of summer and winter freshes to: maintain instream habitat for aquatic plants, water bugs and fish by scouring pools, submerging snags, and maintain water quality. The delivery of environmental water targets the reach from Caseys Weir to Waggarandal Weir (reach 1), which also benefits the downstream reaches from Waggarandal Weir to Katamatite (reaches 2 and 3). To date environmental water has not been delivered down the upper Broken Creek due to the limited availability of environmental water in the system and creek capacity information.
