 Several years ago, Neverfear Weir breached, leaving an unsightly pile of debris. Unfortunately,​ despite collapsing, the weir still presented a partial barrier to the movement of fish due to the way the debris blocked the river. The loss of the weir was regretted by some as it was an attractive spot and it gave the Moss some of its character as a site of early industry. Furthermore,​ the loss of deep slow flowing river habitat upstream meant that this river stretch was no longer suitable for the coarse fish species that had for many years been fished for by locals. Several years ago, Neverfear Weir breached, leaving an unsightly pile of debris.

 However, from an ecological perspective the collapse of the weir was more positive. The weir presented a major barrier to the movement of fish like Brown Trout that would naturally be found in the Moss. Such barriers suppress fish populations as they inhibit their ability to move through the river system to forage, breed, shelter and disperse. ​   ​ However, from an ecological perspective the collapse of the weir was more positive.

-Through a combination of manual clearance and the employment of a digger and drill we were able to clear the debris and rubbish at the weir. Fish can now easily pass upstream of the weir, and many think the spot looks better now it has been cleared.  +Through a combination of manual clearance and the employment of a digger and drill we were able to clear the debris and rubbish at the weir.

 A problem caused by the loss of Neverfear Weir is that it stopped diverting a flow of water into a goit that had previously fed Neverfear Dam. An attempt had been made to rectify this by diverting a stream into the goit, but over time the bank wall had eroded away allowing water escape back into the main river. During this last very dry summer water levels in the dam dropped very low.  A problem caused by the loss of Neverfear Weir is that it stopped diverting a flow of water into a goit that had previously fed Neverfear Dam.
