Rothley Brook is a small tributary of the River Soar flowing through Leicestershire in the East Midlands of England. This intimate brook winds through a mix of agricultural land and village settings, including the parish of Rothley, offering a classic English lowland stream experience. The brook supports a surprisingly diverse fish community for its modest size, with water quality assessments rating fish populations at a "High" ecological status. The riparian zone features characteristic lowland stream habitat with grassy banks and mixed vegetation, and the brook's substrate includes areas of gravel and cobble that support both fish and invertebrate communities. The catchment has faced historical water quality pressures, including a significant pollution incident in 2016, but ongoing environmental monitoring and improvement efforts continue to support the brook's ecological recovery and long-term health.
