Black River (Ohio)
Project Status: modeling
The Black River is located in north-central Ohio, and discharges to
the Federal navigation channel at Lorain Harbor in Lake Erie. The total watershed
area encompasses 467 square miles and includes portions of Lorain, Medina,
Ashland, Huron and Cuyahoga counties. The major sub-watersheds include
the French Creek, East and West Branch, and Black River mainstem. The
watershed drops from roughly 1,130 feet in elevation to about 570 feet
from the upper to the lower basins.
Land use within the watershed
is comprised of roughly 51 percent agricultural, 38 percent rural, 7
percent urban residential, 3 percent commercial, and 1 percent industrial.
Land disturbances due to high residential growth and intensive agriculture
practices erode the soils within the basin, causing significiant sediment
transport to the lower reaches of the river and into Lorain Harbor.
Numerous dams and reservoirs are also utilized throughout the watershed
as water supply sources and for recreational purposes.
SWAT and BASINS modeling was used
to evaluate sub-watershed sediment transport and yield within the Black
River basin. VFSMOD was also used to develop buffer
strip trapping effectiveness in sub-watersheds identified by initial
SWAT model runs.
Modeling for the Black River
project was completed in August 2007, and a training workshop for state
and local partners was held in September 2007.
Use and Applications
The buffer strip modeling capabilities will be used by soil and water
conservation districts to identify priority agricultural locations causing
nonpoint source sedimentation and encourage implementation of buffer
strips through the CREPS program. The Ohio EPA plans to use the SWAT
model to further develop their assessment of TMDLs throughout the watershed.
Lorain County also plans to use the SWAT model to identify
urban Best Management Practices (BMPs) needed to control sedimentation
in the rapidly developing French Creek subwatershed.
