Another complete fishing ban has gone into effect on the Sacramento River through much of Redding to save the Winter-run Chinook Salmon from extinction. In 2014 and 2015 approximately 95% of eggs and young Salmon were lost due to elevated water temperatures. The once-abundant Chinook used to spawn in the upper reaches of the Sacramento River tributaries such as the McCloud and Pit Rivers but those spawning grounds were blocked by Shasta Dam. The population recovered in the 40’s and 50’s as cool water was released in the Summer months but a sharp decline that started around 1970 hit a low of about 200 fish in the early 90’s, when the species was declared endangered. The state Fish and Game Commission has made permanent the seasonal closure of 5.5 miles of the Sacramento River to all fishing. The ban stretches from Keswick Dam to the Highway 44 bridge in Redding, where 98% of the in-river spawning is believed to occur. The ban covers all fishing because of the danger of Chinook being accidentally snagged by someone fishing for Trout or Steelhead. The total ban continues until July 31st.
