The Batavia Kill project will include the replacement of three culverts that will reconnect over 4 miles of high-quality headwater habitat for Brook Trout. Location chosen as the highest priority site for potential culvert replacement project as part of TU’s East Branch Delaware River Trout Habitat Improvement Project.
The team will use NYS stream crossing standards and US Forest Service stream simulation
design methodology to design the culvert replacement project. A well-designed culvert
should avoid constricting the stream channel, consider the width and skew of the river as well
as be appropriately sized to pass the largest storm feasible - ideally, the 1% storm with
adjustment for climate change (20% in this region of NY). The structure should maintain the
continuity of the natural stream substrate, slope, and water velocity through the structure.
Non-constricting culverts installed with a similar natural slope will normally provide water
depths, velocities, bottom substrates, and channel characteristics that are comparable to the
natural stream.i Since stream hydraulic characteristics within the culvert are intended to
mimic the natural stream conditions upstream and downstream of the crossing, this design
method ensures that stream flow, velocity and water depth are appropriate for fish passage.
Brook Trout specific physiological characteristics will also be considered during the design
process.
