The lake and adjacent park feature wildlife and recreation. The American Power Boat Association (APBA) and the DePue Men's Club (a social and volunteer organization) host a weekend of boat racing on Lake DePue. The event draws spectators from across the country and brings entertainment and food vendors to the lakeside park. Barack Obama visited when he was an Illinois legislator. In a January 16, 2011, news story featured in the online edition of the Peoria Journal Star, Associated Press reporter Tammy Webber reported that the oxbow lake, surrounded by a Superfund site, is polluted by high levels of metals such as zinc, lead, arsenic, cadmium, and chromium because of smelting activity there for the automotive and appliance industries, chiefly by New Jersey Zinc and Mobil Chemical. The village is urging Illinois Attorney General Lisa Madigan to investigate whether the Illinois Environmental Protection Agency, which has oversight over the case, is pushing the companies hard enough. This is important because the town alleges the companies and the IEPA have not done enough to combat the pollution, that has made the lake markedly shallower. This phenomenon could, unless rapidly remedied (perhaps by the temporary fix of dredging, which the IEPA cannot legally order in this case), soon interfere with the small municipality's efforts to keep its remaining revenue source for most supplemental projects, the competition. The manufacturing jobs have entirely disappeared.
In the summer of 2012, as a result of both the summer's drought and Lake DePue's pollution, the APBA nearly cancelled its National Championship Races due to shallow water. In a display of community and hard work, DePue's citizens built a dam at the mouth of the lake and raised the water, by pumps and the lake's springs, to racing level in a matter of weeks.
