Sockeye had maximum run in 1993 (blue line chart below) so looks healthy; chum and coho runs were highest in 1962 & 1959 respectively – needs more info.

Lower Grenville Systems & Fishery

 

LOWE INLET

----Lowe Inlet is well known for its sport fishing on lakes and wildlife viewing possibilities. FISS literature says good deal investigative work about enhancing sockeye. A DFO escapement database shows Lowe was once a good sockeye producer. Earlier logging may be the culprit, as something happened in mid-1970s.

DFO online Escapement Data not available for Lowe Inlet systems

Good Pink Runs

Historically odd year Pinks 15T (’85); Even Pinks 8T 1986

Chum 7.5T (’57) and coho 1.5T(’65)

Sockeye very low numbers( 2?)
 
 
Belowe Lake watershed health

System appears to be in good shape, at least for Pinks.
Sockeye interesting – Chum and Coho appear in serious trouble-possibility enhancement?
