Ben Gill, Cumbria – Back to Nature
Engineering work on the weir of Ennerdale Water in the 1950s raised the level of the lake, increasing its storage capacity and ensuring a more secure potable water supply. As part of this work, one of the tributaries of the River Ehen (Ben Gill) was diverted to Ennerdale Water via… ∞
Ogden IR Advance
Following flood studies and physical modelling it was determined that the existing Ogden Reservoir was unable to pass a Probable Maximum Flood (PMF). To accommodate the PMF event, the existing spillways and overflows needed improvement. However to enable these improvements to be carried out, advanced works were required to divert… ∞
Ogden IR Temp Bridge
Flood studies and physical model tests demonstrated that the original overflow and spillway facilities at the Ogden Impounding Reservoir were unable to pass the Probable Maximum Flood (PMF) without overtopping onto the main earth embankment with a consequent risk of failure due to the destructive action of out-of-channel flows. The… ∞
Ogden IR Wedge Block
Flood studies and physical model tests demonstrated that the original overflow and spillway facilities at the Ogden Impounding Reservoir were unable to pass the Probable Maximum Flood (PMF) without overtopping onto the main earth embankment with a consequent risk of failure due to the destructive action of out-of-channel flows.

Holden Wood IR
Flood studies and physical model tests demonstrated that the existing overflow and spillway facilities at the Holden Wood Impounding Reservoir were unable to pass the Probable Maximum Flood (PMF) without overtopping onto the main earth embankment with a consequent risk of failure due to the destructive action of out-of-channel flows…. ∞
