Big Roche-A-Cri Lake is primarily a recreational lake used for fishing, boating, jet skiing and water skiing. Please check the WI DNR or signage for both fishing restrictions and wake rules which are currently no wake after 6:00 pm. You can find the most common Wisconsin fish in the lake including northern pike, largemouth bass, blue gills, crappies and other types of panfish. Most of the 6.7 miles of shoreline real estate around the lake has been fully developed into waterfront building sites for getaway cabins, full time residential homes, mobile homes and campers. State hwy 13 splits the lake in two with the smaller east side being shallow & weedy with the larger West side, much deeper and it’s less weedy toward the dam and some of the nicer homes. The contour of the bottom of the lake is made up of the old creek bed, some rock but mostly sand and silt that the creek brings in. The Lake association has the weeds harvested throughout the summer months.
There are two primary boat launches on the lake for small to mid size fishing, ski and pontoon boats. One is next to the hyrdo dam and the other right next to hwy 13 just south of Reze Bar & Grill. If you need gas, fishing equipment, sandwiches, soda, or even a movie, you will find them at the Country Deli & Grocery which is less then a block from Big Roche-A-Cri Lake, in Central WI.
