Catch per net (CPUE) is the DNR survey's count per gill net or trap net set; higher means more of that species were sampled, not a fishing forecast. Top species per gear shown; where we have no verified common name for a DNR code, the code itself is shown.
Square Lake is a 203 acre, class 23 lake located in northeastern Washington County. The water quality in Square Lake is among the best in the Twin Cities metro area, a secchi disk reading in 2014 was 18.0 feet, and the lake supports a diverse near shore fish community. A near shore Index of Biotic Integrity survey (IBI) was conducted on August 10-11, 2016 to assess populations of non-game species, young-of-the-year (YOY) sport fish, and overall lake health using backpack electrofishing and seining. Electrofishing with a backpack unit and seining were conducted at 10 stations around the perimeter of Square Lake. Eight different species including Iowa Darter, Johnny Darter, Banded Killifish, Blacknose Shiner, Bluegill, Bluntnose Minnow, Central Mudminnow, and Spotfin Shiner were sampled by backpack electrofishing. Bluntnose Minnow and Spotfin Shiner were the most abundant species sampled by backpack electrofishing. Thirteen species were sampled by seining including Iowa Darter, Johhny Darter, Banded Killifish, Blackchin Shiner, Blacknose Shiner, Bluegill, Bluntnose Minnow, Central Mudminnow, Green Sunfish, Largemouth Bass, Pumpkinseed, Spotfin Shiner, and Spottail Shiner. Bluegill, Bluntnose Minnow, and Spotfin Shiner were the most abundant species sampled by seining. (Insert info from Jacquelyn here)
