The boundary is open to revisions during the feasibility study process. I trout streams contain high-quality habitat for trout including spawning ground, adequate food resources, and excellent water quality so that no stocking is required. Class II trout streams have adequate food resources and living space, but lack sufficient natural reproduction so that some stocking is required. Class III trout streams have marginal trout habitat and require stocking annually. Wetlands vegetated with grasses, sedges and showy flowering plants like marsh milkweed, goldenrods and asters.
Woody plants are absent and standing water is present only after heavy rains.
Wet meadows are especially important for water quality protection since they are generally the buffers between uplands and waterways where their dense vegetation traps sediments and takes up nutrients. They also retain floodwater and provide wildlife habitat for many species including cranes, pheasants, and many small mammals that provide food for mink, fox and raptors. The WTL was available from 1954 to 1986. The last contracts expire December 31, 2000. Public access is not required.
