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.

South Ten Mile Lake is located in southwestern Otter Tail County approximately five miles southwest of Dalton, MN. South Ten Mile Lake is a 1,411-acre mesotrophic (moderately fertile) lake that is part of the Pomme de Terre River Watershed. The Pomme de Terre River inlet is located along the north shoreline while the outlet is located along the south shoreline. The inlet is navigable by boat through a culvert into North Ten Mile Lake. The immediate watershed is composed primarily of agricultural land interspersed with hardwood woodlots. The maximum depth of South Ten Mile Lake is 51 feet; however, 42% of the lake is less than 15 feet in depth. The Secchi disk reading during the 2024 survey was 11.1 feet. Previous Secchi disk readings have ranged from 4.0 to 14.5 feet. The east and west shorelines of South Ten Mile Lake have been extensively developed. Homes and cottages compose the majority of the development. A resort is located on the north shoreline. A DNR owned public access is located along the southeast shoreline. Shoreline development has recently increased in the southern portion of the lake. Common cattail and hardstem bulrush are prevalent along the shoreline of this bay. Large stands of hardstem bulrush are also located along the south, west, and east shorelines of the main lake basin. Emergent aquatic plants such as bulrush and cattail provide valuable fish and wildlife habitat and are critical for maintaining good water quality. They protect shorelines and lake bottoms and absorb and break down polluting chemicals. Emergent plants provide spawning areas for fish such as Northern Pike, Largemouth Bass, and panfish. They also serve as important nursery areas for all species of fish. Because of their ecological value, emergent plants may not be removed without a DNR permit. To maintain the excellent water quality and angling that this lake has to offer, it is imperative to preserve the quality of the aquatic habitat. A cooperative shoreline stabilization project was completed in 1999. The DNR, in conjunction with the lake association and private landowners installed rock rip-rap to stabilize several areas of shoreline that were experiencing varying degrees of erosion. A spring trap netting survey was conducted in 2025 to collect data on the Bluegill population. This was the first survey specifically targeting Bluegill on South Ten Mile Lake. A moderate density Bluegill population exists, with quality fish present as well. Age data indicates that Bluegill recruitment has been inconsistent in recent years. Fish sampled ranged in size from 3.4…
