However, Hertfordshire's population increased substantially in the second half of the twentieth century, and the consequent demand for water has affected rivers such as the Beane and the Mimram.

An indication of the scale of the decline in flow is that the section at Walkern was once big enough to power a watermill and to support watercress beds.

[2] The lower Beane is more robust and there has continued to be regular flow through Watton-at-Stone, Stapleford and Waterford until the confluence with the River Lea.

[7] One possible approach to the restoration of the upper Beane which was discussed was to use recycled water from sewage treatment works.

[9][10] Herts and Middlesex Wildlife Trust (HMWT) has launched a circular trail at Waterford, which includes some scenic sections of the River Beane.
