Corps of Engineer lakes in Oklahoma being evaluated for Whooping Crane “stopover habitats”

By Pam Bates, Friends of the Wild Whoopers

Whooping Cranes migrate 2,500 miles two times each year between their nesting area in Wood Buffalo National Park, Canada and their Aransas Wildlife Refuge winter habitat on the Texas coast. During these migrations they must stop to rest and feed 15 to 30 times. Friends of the Wild Whoopers (FOTWW) is searching for areas to provide these essential “stopover habitats”. Stopover habitats are equally as important as nesting and winter habitats.

Fort Supply Lake

Fort Supply Lake in northwest Oklahoma is one of four Corps of Engineer (COE) Lakes that have recently been evaluated to determine if they have any existing or potential “stopover habitat” for migrating Whooping Cranes.  FOTWW visited the four lakes as part of its continuing efforts to encourage protection and management of decreasing habitat for migrating Whooping Cranes.

Despite heavy rainfall, flooding and high water levels in three lakes FOTWW‘s wildlife Biologist Chester McConnell explained that: “Our evaluation team continued towork in the challenging conditions. Fortunately COE and Oklahoma Wildlife Division (ODWC) personnel accompanied me and they were well informed about the lake’s habitats. So, together, we successfully identified some good stopover habitat sites.” Fort Supply Lake is just one of many COE lakes that FOTWW has, and will be evaluating. The Operation Management Plan FY 2014 thru 2018 covers information for the COE area of primary management responsibility. The “Wildlife Management/Hunting program” is described in a separate document prepared by ODWC. The lake was authorized under the Flood Control Act approved June 22, 1936. Construction of the lake was begun in October 1938 and completed in August 1942.  There is a total of 9,899 acres of project land and water. The lake covers 1,786 surface acres of open water. A total of 8,079 acres are used for wildlife management, recreation and project operations. Although the primary mission is flood control, important secondary benefits are water supply, recreation, and natural resource management. Importantly one of the natural resources needing the lake is the only wild population of wild Whooping Cranes remaining on earth.

Whooping Cranes observed at fort supply lake

FOTWW is aware that Fort Supply Lake, has been used by Whooping Cranes and we expect that to continue and increase. Both USACE and ODWC personnel have observed Whooping Cranes on the lake several times.

These men are very informed about the lake and its surrounding wildlife habitats, vegetation and water levels. McConnell said “Their assistance was invaluable and greatly appreciated.”  Photo by Chester McConnell, Friends of the Wild Whoopers.

Fort Supply Lake, Oklahoma Figure 2. The short grass, shallow water and absence of trees and bushes in this photo cause it to be suitable for Whooping Crane “stopover habitat” during normal water levels. During our evaluation, abundant rain (8+ inches) caused the lake depth to be deeper than normal. Water depths vary occasionally due to abundant rain and long drought periods. Importantly, due to various shore configurations, when one area of a lake is not suitable, some other area of the lake will likely be suitable.

Fort Supply Lake, Oklahoma Figure  3. This photo identifies a 3 to 4acre site near the lake that could be developed into a shallow water“stopover  habitat” (3 inches to 6 inches deep) for Whooping Cranes and other wild creatures. The vegetation in the area could be treated with herbicide and burned when dry. A low level berm as outlined can be constructed around the developed pond to hold shallow water for a “stopover habitat”. This small wetland would operate independently from the water levels in the lake. Photo by Chester McConnell, Friends of the Wild Whoopers.

Whooping Crane “Stopover Ponds/Wetlands” Plans

By Chester McConnell, Friends of the Wild Whoopers

Landowners and other land managers often contact Friends of the Wild Whoopers wanting to know how they can help endangered wild Whooping Cranes. Normally we discuss needs by phone or email. To simplify the process we have developed a brochure to provide information concerning one major and growing need.

This need is to properly manage existing ponds/wetlands or develop new ponds/wetlands so that they will attract Whooping Cranes. These amazing birds migrate 2,500 miles two times each year between their Canadian nesting grounds and their winter habitats on the Texas coast. During these long migrations they must stop to rest about 10 to 15 times.

While there are about a dozen prime stopover sites on wildlife refuges, migrating Whoopers mostly stopover on small ponds/wetlands on private farms just to rest overnight. Over the years thousands of stopover areas have been destroyed due to changes in land use. As the Whooper population continues to increase there is an increasing need for more stopover sites on private lands. The focus for these ponds/wetlands is in North Dakota, South Dakota, Nebraska, Kansas, Oklahoma and Texas.

If you own land would you share a small amount with Whooping Cranes? And if you are not a landowner, possibly you could partner with one to help prepare a stopover pond. Ponds can be about any size from one-third acre and larger. The USDA Natural Resources Conservation Service (NRCS) has cost share funding and technical support that will provide dollars to landowners needing assistance. It is also important to know that ponds developed or managed for Whooping Cranes also provide habitats for many other kinds of fish and wildlife.
