Green County, Wisconsin
SP01

0.00 - 5.96
5.96
Water is impaired due to one or more pollutants and associated quality impacts.
Notes
TMDL approved 2005.
Twin Grove Branch is located in southern Green County and is part of the Honey and Richland Creek watersheds.
Originating just east of the town of Twin Grove, the six-mile long stream flows westward and empties into Richland
Creek. The entire length of Twin Grove Branch is currently listed on the 303(d) list for degraded habitat resulting
from sedimentation due to agricultural non-point source pollution. Fish surveys from 1974 and 1976 found 17 species
of forage and minnow species between two different locations near the mouth of the stream. The most abundant
species found were central stonerollers, white sucker, and creek chub; however, the stream has not been monitored in
recent years. Twin Grove Branch currently supports a warm water forage fishery, but is believed to have the potential
to become a warm water sport fishery.
