For those who didn't know what was going on, the activity on Cedar Lake this past Saturday was likely a big mystery.
About 30 volunteers spent their day helping to improve fishing on Cedar Lake.
At 8 a.m. Saturday morning the crew showed up to construct fish cribs from logs, tree branches and concrete weights. The day wrapped up around 1 p.m.
The finished cribs were pulled into place at two strategic locations out on the ice. Come spring, when the ice melts, the cribs will sink to the bottom of the lake and provide small fish a safe place to grow.
The crib project started in 2004, a joint effort by the Star Prairie Fish & Game organization, Cedar Lake Rehabilitation District and the Wisconsin Department of Natural Resources.
Forty-six new cribs were constructed this year, bring the total number of cribs on Cedar Lake to 178, according to Don Demulling, secretary of the Cedar Lake Rehabilitation District.
Project organizers hope to place several hundred fish cribs around the lake in the coming years.
The cribs are needed to improve fish populations in the lake. There is not much vegetation on Cedar Lake because of the poor water quality. Weeds grow in the lake during the early months of the spring. But as summer temperatures heat up, algae blooms choke off the sun and kill many of the plants.
When the weeds disappear, fish congregate toward the cribs for protection and food sources.
The cribs are placed in water that's between 14 and 20 feet deep to avoid disruption of boating activities.
