The U.S. Army Corps of Engineers staff at Hillsdale Lake manages the lake to provide benefits to the nation in areas of Flood Damage Reduction, Water Supply, Water Quality Improvements, Fish and Wildlife Management and Recreation. The Hillsdale Lake staff also operate the project Visitor Center.

The Corps manages 4,580 surface acres of water and over 8,000 acres of public land surrounding the lake. The staff conducts dam safety inspections and maintains the dam and outlet works. Corps employees make water release changes to Big Bull Creek which flows into the Marais des Cygnes River. All releases are conducted in coordination with the Kansas City District Water Management Section and the Missouri River Region Control center. Hillsdale Lake is part of the Osage River Basin along with Melvern, Pomona, Stockton, Pomme de Terre and Harry S. Truman Lake.

In 1989, the Kansas Department of Wildlife, Parks and Tourism leased 12,880 acres of land and water at Hillsdale to be managed as a Kansas State Park & Wildlife Area. Today, all recreation facilities and wildlife management lands are managed by the Kansas Department of Wildlife, Parks and Tourism.

The Corps of Engineers manages the Visitor Center located at the lake. They provide local, regional and national information to the visiting public. Adjacent to the Visitor Center is a 1.5 mile nature trail called "The Hidden Spring Nature Trail". The trail is managed as an extension of the Visitor Center. In addition to the Nature Trail, there is a Group Shelter house that can be reserved.

Other activities conducted by the Corps include: dam operations, natural resource management, water safety, public relations, visitor services, real estate management, noxious weed control, collection of weather data, lake patrol, buoy maintenance, and encroachment surveillance.

Hillsdale Lake is a U.S. Army Corps of Engineers operated multi-purpose use reservoir located in Miami County near Paola, Kansas on the Big Bull River in the Lower Kansas River Basin. The Flood Control Act of 1954 authorized Hillsdale reservoir for flood control, water supply, water quality, recreation and fish and wildlife use and has a 144 square mile drainage area. Hillsdale Lake is part of the Osage River Basin along with Melvern Lake, Pomona Lake, Stockton Lake, Pomme de Terre Lake and Harry S. Truman Lake. Together, these lakes function as a system to play a vital role in managing water resources. USACE is authorized to operate Hillsdale Lake using the current Water Control Manual that was prepared by the Kansas City District and is dated June 1985. 

Congress provided direction and funding in Fiscal Year 2022 for USACE districts across the nation to update Water Control Manuals, or WCMs to evaluate whether any changes in physical, social and environmental conditions around the dam warrant updating the WCP, include a drought contingency plan and meet new requirements for formatting and updating information.


WHAT IS A WATER CONTROL MANUAL?

Water Control Manuals, or WCMs, are operating manuals for U.S. Army Corps of Engineers, or USACE, dams. USACE makes day to day decisions about releasing water through its dams according to Water Control Plans, or WCPs, that are included in dam specific-WCMs. The objective of all WCMs include operating the dam and reservoir for the purposes authorized by Congress and other applicable law, maintain the structural integrity and operation integrity of the dam (sometimes called a “project” to include reservoir operations) and avoid risk to public health and safety, life and property.

The WCMs are being updated because Congress provided direction and funding in Fiscal Year 2022 for USACE districts across the nation to update WCMs to evaluate and potentially update WCPs as necessary, include a drought contingency plan for managing water releases from dams when there is a drought and meet new requirements for formatting and updating information. Each WCM and its WCP was developed when each project was authorized. They are updated periodically to determine whether there are changes in the physical, environmental and social conditions that need to be accounted for in a dam’s operation.  


NEPA PROCESS

The National Environmental Policy Act (NEPA) is a law that requires all federal agencies to take a 'hard look' at how their actions may affect the human and natural environment. It spells out the steps an agency must take to identify environmental issues that need to be considered, identify options or alternatives that would correct the problems identified and explain its final decision while complying with environmental regulations. NEPA also gives the public a voice in the decision-making process about the proposed actions. The public is asked to provide input through public meetings and opportunities to provide written comments. The first opportunity happens during the scoping phase. Additional opportunities occur when the environmental review is complete and alternatives for action identified. These comments will be considered before the federal agency makes a final decision.

*
  • Water Control Manuals, or WCMs, are operating manuals for U.S. Army Corps of Engineers, or USACE, dams.
  • USACE makes day to day decisions about releasing water through its dams according to Water Control Plans, or WCPs, that are included in dam specific-WCMs.
  • All WCMs have the following objectives, in addition to the WCP guidelines:
  1. Operate the dam and reservoir for the purposes authorized by Congress and other applicable law;
  2. Maintain the structural integrity and operation integrity of the dam (sometimes called a “project” to include reservoir operations); and
  3. Avoid risk to public health and safety, life and property.
  • Congress provided direction and funding in Fiscal Year 2022 for USACE districts across the nation to update WCMs to:
  1. Evaluate and potentially update WCP’s as necessary.
  2. Assess existing drought contingency plan for managing water releases from dams when there is a drought.
  3. Meet new requirements for formatting and updating information.
  • Each WCM and its WCP was developed when each project was authorized. They are updated periodically to determine whether there are changes in the physical, environmental and social conditions that need to be accounted for in a dam’s operation.  
  • The Kansas City District is now working on twelve projects.
  • The Pomme de Terre WCM, the Harry S Truman WCM and four projects in the Lower Kansas River Basin - Clinton, Perry, Milford and Tuttle Creek Lakes – are currently underway.
  • In fall 2023, the team will begin work on Hillsdale, Melvern and Pomona Lakes, and will begin Kanopolis, Wilson and Harlan County Lakes at the start of 2024.
  • All twelve updates will be completed between 2026 and 2028.
  • The Kansas City District will:
    • Investigate whether any changes to environmental, physical and social conditions justify adjustments to the way USACE operates a dam and lake.  
    • Evaluate how the lakes work as a system so that USACE can decide how to control releases. By controlling releases, USACE can manage risks from floods and droughts downstream from the dams and support a lake’s authorized purposes.
    • Explore ways to recognize and respond to drought conditions in order to benefit project authorized purposes.
    • Identify disadvantaged communities and integrate them into planning for water resources in the Kansas River Basin.
  • The Kansas City District will not:
    • Change any releases regarding navigation.
    • Add or remove federally authorized purposes for a lake.
    • Increase or decrease existing lake project storage allocations.
    • Change the total volume of flood risk management reservoir discharges passing from the reservoirs to the river below.
    • Address specific issues such as lake sedimentation, recreation planning and fish stocking.
  • USACE will conduct “scoping” under the National Environmental Policy Act (NEPA)*.  Scoping happens at the beginning of an environmental review. It helps identify the issues the environmental review should consider in detail.
  • USACE technical staff in the Kansas City District will collect engineering, environmental and demographic data to assess current conditions at each reservoir.
  • During scoping:
    • USACE will share the steps of the update process with the public, Tribes, local governments, states and other federal agencies.
    • USACE will describe what it has learned through assessment of current conditions at each dam and reservoir and summarize the steps forward. 
    • USACE will elicit public input at public meetings and through written comments.
    • USACE will use this input, along with information about any new physical, environmental, economic and social conditions, to develop a set of alternatives for lake operations.
  • Once the alternatives for reservoir operations are developed:
    • USACE will evaluate the potential impacts of the proposed updates in a draft environmental review under NEPA. 
    • The public will have the opportunity to review that draft and provide comments.
    • USACE will evaluate and incorporate responses to the public comments in the final environmental review along with the final decision about updates to the WCM and the WCP.
