The Iowa Department of Natural Resources (DNR) Lake Restoration Program (LRP) will accept public comments on the newly released draft 2026 Lake Restoration Report and 2025 Plan, beginning Dec. 5.

The report is available for review at www.iowadnr.gov/Lake-Restoration. It highlights restoration projects completed around the state in State Fiscal Year (SFY) 2025 and outlines plans for upcoming restoration projects.

The Lake Restoration Program works with communities and stakeholders across Iowa to improve water quality and recreational opportunities at publicly-owned lakes. Since the program’s creation in 2006, the Iowa legislature has invested over $176 million in the lake restoration program, with investments at 72 lakes in 55 counties statewide. The program averaged a 37 percent cost share to match LRP funds by other project partners in SFY2025 (local, federal, and other state funds).

Lakes are an important part of Iowa’s economy, accounting for $1.32 billion in annual spending. In 2024, Iowa’s lakes had more than $13.7 million visits statewide. More than 60 percent of Iowans visit a lake at least once per year, and on average, visitors spend an average of $36 on single day trips. Visitors consistently rank proximity to their work or home, quality of facilities, and water quality as their top reasons when choosing a lake to visit.

Accomplishments since the program’s inception include:

• 40 miles of shoreline protection to minimize erosion
• 7.7 million cubic yards of excess sediment removed (equivalent to over 513,000 dump trucks of material)
• 44 projects enhancing 14,000 acres of wetlands and shallow lakes
• Over 250 watershed best management practices (BMPs; e.g. ponds, grade stabilization structures, urban stormwater BMPs, and upland/stream restoration) implemented with program funds on public lands
• Over 700 BMPs constructed in priority watershed in concert with project partners (e.g. NRCS, SWCDs, US EPA Section 319, IDALS, Municipalities) to protect downstream lakes
• 60 infrastructure improvement projects (e.g. dam/spillway repairs, lake outlet water control structures, fish barriers) to preserve Iowa’s lakes for the next generation

Major projects completed in 2025 include a $3.52 million investment in Three Mile Lake, (Union County), a $2.92 million investment at Casey Lake (located within Hickory Hills Park, Black Hawk County), a $987k investment at the Iowa Great Lakes to assess shoreline damage from the 2024 floods, and a $1.8 million investment at Prairie Rose Lake (Shelby County) and Green Valley Lake (Union County) for phosphorus inactivation treatments.

Major projects planned for 2026 include completion of the projects at Lake Keomah (Mahaska County), and McKinley Lake (Union County), shoreline stabilization projects at the Iowa Great Lakes to address flood damage, and beach restoration projects at Brushy Creek Lake (Webster County), Big Creek Lake (Polk County), and Hickory Grove Lake (Story County), to reduce bacteria concentrations at each of these beaches. Several large-scale shallow lake/wetland restoration projects are underway, including projects at East Twin Lake (Hancock County) and Little Storm Lake (Buena Vista County).
