Susquehanna River, North Branch

Despite low river levels throughout the North Branch Susquehanna River, Commission biologists completed their annual assessment of young of the year walleye. This was the 7th consecutive autumn survey of young of the year walleye abundance. Based on spring river flows it was anticipated that there would be good numbers of young walleye and that was certainly the case.

The average catch rate was 111 walleye per hour of electrofishing. River flows during the spring have a major impact on the success of walleye reproduction. High spring flows result in weak year classes while normal spring flows result in good numbers of young walleye.

Over the past seven years the average catch rate during poor years (1996, 1998 and 2000) has been 6 per hour with good years (1995, 1997, 1999 and 2001) averaging 139 per hour.
