Ravine Lake (unnamed 82-0087-00) is located in Cottage Grove Regional Park and has been in the Fishing in the Neighborhood (FiN) Program since 2001. The park is managed by Washington County Parks and requires an entrance permit of $5.00 daily or $25.00 annually. The park has a playground, picnic shelter, restrooms, ample parking, and wooded hiking trails. The lake is 25 acres with a maximum depth of 16 feet. The entire shoreline is undeveloped and provides habitat for a variety of wildlife. The lake is a good place to watch for egrets, herons, eagles, ospreys and waterfowl. There is a shore fishing station and a fishing pier on the northeast shore. The pier makes angling easier in the mid-summer when dense vegetation grows near shore. For canoe or kayak anglers, carry-in access to launch and land watercraft may be found near the south end of the lake. The lake is primarily managed for Walleye and Bluegill Sunfish with secondary management emphasis on Largemouth Bass and Black Crappie. Walleye fingerlings and/or adults have been stocked every year since 2002. They were sampled in moderate numbers and mostly small size, with lengths ranging from 13 to 15 inches. Bluegills were sampled in above average numbers with good size (6.0 to 7.5 inches) compared to lakes similar to Ravine. Black Crappies were found in moderate to low abundance and most were between 7.5 and 9.0 inches. Yellow Perch were sampled moderate to low numbers with lengths ranging from 7.0 to 10.0 inches. The discovery of Yellow Perch in 2016 was a surprise and probably the result of an introduction via a bait bucket dumping or intentional stocking, both of which are illegal activities. Also sampled in moderate to low numbers respectively were Hybrid Sunfish, Northern Pike, Pumpkinseed and White Sucker.

The lake is primarily managed for Walleye and Bluegill Sunfish with secondary management emphasis on Largemouth Bass and Black Crappie. Walleye fingerlings and/or adults have been stocked every year since 2002. They were sampled in moderate numbers and mostly small size, with lengths ranging from 10 to 26 inches. Bluegills were sampled in above average numbers in good size (6.0 to 7.5 inches) for lakes such as Ravine. Black Crappies were found at the same abundance as the last assessment (2011) with only 7 Black Crappies documented in 2016. Most fish were between 7.5 and 8.0 inches, with the largest being slightly over 8.0 inches. Since the last assessment in 2011, Largemouth Bass abundance has declined with only one 13.5 inch fish sampled. Yellow Perch were sampled for the 1st time in Ravine during this assessment. One Yellow Perch each was sampled in the trap nets and gill net. Yellow Perch lengths ranged from 7.5 inches for the gill net to 9.2 inches for the trapnets. The discovery of Yellow Perch was a surprise and probably is the result of an introduction via a bait bucket dumping, which is an illegal activity. In previous assessments of Ravine Lake Black Bullheads were very numerous, but none were documented during this survey. Also sampled in moderate to low numbers respectively were Hybrid Sunfish, Green Sunfish and Pumpkinseed.

Ravine Lake (unnamed 82008700) is located in Cottage Grove Regional Park. The park is managed by Washington County Parks and requires an entrance permit of $5.00 daily or $25.00 annually. The park has a new playground, picnic shelter, restrooms, ample parking, and wooded hiking trails. The lake is 25 acres with a maximum depth of about 16 feet. The entire shoreline is undeveloped and provides habitat for a variety of wildlife. The lake is a good place to watch for egrets, herons, eagles, ospreys and waterfowl. There is a shore fishing station and a fishing pier on the northeast shore. The pier makes angling easier in the mid-summer when dense vegetation grows near shore. The lake is primarily managed for walleye and bluegill with secondary management emphasis on largemouth bass and black crappie. Walleye fingerlings and/or adults have been stocked every year since 2002. They were sampled in low numbers and small size, with lengths ranging from 6.5 to 11 inches. Bluegills were sampled in moderate to above average numbers but again, small in size for lakes such as Ravine. The most common size group was 3.0 to 5.0 inches. Only 8% of the sample was over 6 inches, and the largest bluegill sampled was 7.5 inches. Black crappies are less abundant than in past assessments with only 8 black crappies documented in 2011. Most fish were between 8.5 and 9.0 inches, with the largest being 9.5 inches. Since the last assessment in 2006, largemouth bass have remained fairly abundant. Trap netting found good numbers of largemouth bass, however they are small 4.5 to 8.5 inch juvenile fish. The brown bullhead catch was high, with lengths ranging from 8.5 to 11.5 inches. The brown bullhead is a species of catfish that is not commonly found FiN ponds or lakes. If you are looking to catch brown bullheads then Ravine Lake is a good lake to meet that goal. In previous assessments of Ravine Lake black bullheads were very numerous, but none were documented during this survey. Also sampled in moderate to high numbers were hybrid sunfish, green sunfish and pumpkinseed. The lake has been stocked with several hundred adult white bass in 2004, 2005, and 2006, but none were sampled in this assessment.
