The name of the river which was dammed to form the lake in this photo was a pointless answer on the BBC Quiz show 'pointless'. I got it.

(SE = 7.2) Basics to 28

Basics to UP = 28
1. (6)g8 = de8 - f7 = HP(62)f35 - (2)c4 = (2*)c8 - (2=139)c245 - (1,3,9)c8 = (4837)cfhi9 => -2*g8, -7g8 ; UP = 30
2. (6*=3)d4 - (3'=9)e6 - (9)d5 = HP(9*1*)d73 - (1=3')e2 => -6*d37, -3'e4
3. (2)f3 = f5 - (2=6)e4 - d4 = d8 - (6=42)g81 => -2e1|h3 ; UP = 81

Correction: in step 1, (2)c4 should read (2)c5:

1. (6)g8 = de8 - f7 = HP(62)f35 - (2)c5 = (2*)c8 - (2=139)c245 - (1,3,9)c8 = (4837)cfhi9 => -2*g8, -7g8 ; UP = 30
