DNR fish survey, 2024

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.

Pebble Lake is a 169-acre mesotrophic (moderately fertile) lake located within the city limits of Fergus Falls, MN. Pebble Lake is located within the Otter Tail River Watershed. The immediate watershed is primarily composed of residential areas interspersed with hardwood woodlots. The maximum depth of Pebble Lake is 62 feet; however, 39% of the lake is 15 feet or less in depth. Historical secchi disk readings have ranged from 7.3 to 17.5 feet. The south and west shorelines of Pebble Lake have been extensively developed into residential areas. A city park with a public water access and campground is located along the north shoreline of the lake. A city park with a swimming beach and golf course is located along the southwest shoreline of the lake. Shoal water substrates consist primarily of sand and rubble. Emergent aquatic macrophytes such as hardstem bulrush or common cattail are rare except for an extremely small area along the north shoreline. A spring trapnetting survey was conducted to assess the Bluegill population. An abundent Bluegill population with a poor size structure exists. Only two percent of the Bluegills sampled were 8.0 inches or greater in length. Bluegills attain an average length of 7.1 inches at six years of age. Anglers can preserve the quality of fishing by practicing selective harvest. Selective harvest encourages the release of medium to large size fish while allowing the harvest of more abundant smaller fish for table fare. Releasing the medium to large fish will ensure that the lake will have enough spawning age fish on an annual basis and will provide anglers with more opportunities to catch large fish in the future. Pebble Lake is not listed as an infested body of water. Aquatic invasive species are threatening Minnesota waters. The non-native species can potentially harm water quality, water recreation, aquatic habitat, native species, and fish populations. Anglers can help prevent the introduction and spread of invasive species by following watercraft transportation laws. Anglers are required to remove all visible plants, mud, and other prohibited invasive species and drain all water from their boat prior to leaving the water access.
