Euclid Creek

Delisting Status

HUC12 - 041100020503

Euclid Creek, with an area of 23.31 square miles, is the 13th largest HUC12 in the AOC. It is designated as a “Frontal Lake Erie” HUC12 in that it drains directly to Lake Erie.

Its land is 92% developed, which presents significant challenges to reaching delisting targets, especially those related to fish and aquatic life and habitat.

BUIs applicable to Euclid Creek are 1, 3a, 4, 6, 8, 10, 11, and 14a – all the same impairments found in the Area of Concern as a whole, except for restrictions on dredging.

The presence of Euclid and Villa Angela beaches pose special challenges in that high bacteria levels often call for beach closings.

Extensive culverting of the creek, especially at the lower creek where it passes beneath Interstate 90, long stretches of armored banks, and barriers to fish passage such as spillways and dams, are also obstacles to removing fish- and habitat-related BUIs.

BUI 1 - Restrictions on Fish Consumption
in Euclid Creek

This watershed is in attainment for fish consumption in that restrictions to consumption in this watershed are not more stringent than those called for in the State of Ohio Sport Fish Consumption Advisory.

See for more information.

BUI 3a - Degradation of Fish Populations
in Euclid Creek

The delisting target for this HUC 12 is unique in that it has the all of the types of target area scores (lacustuary, riverine, headwaters) outlined in the Ohio EPA Delisting Guidance represented throughout its boundaries.

These include an IBI score of 42 and MIwb score of 8.6 for Lacustuary areas, an IBI score of 34 and MIwb score of 7.5 for wading areas, and an IBI score of 36 for Headwaters (no MIwb score is necessary for headwaters below 20sq miles of drainage).

Analyzing the scores with attainment levels in mind for the sites sampled, this HUC12 is 20.9% below the delisting target. This was calculated taking a weighted average of the credible scores for both
IBI and MIwb throughout this HUC12. This subwatershed is well
below attainment numbers for delisting BUI 3a.


IMPAIRED = 3a Fish Population; 4 Fish Tumors; 10a Beach Closings/Recreational Contact; 11 Aesthetics

NOT IMPAIRED = 1 Fish Consumption; 6 Benthos; 14a Fish Habitat

Not Applicable = 7 Restrictions on Dredging (N/A);

Unknown = 8 Eutrophication

BUI 4 - Fish Tumors and Other Deformities in Euclid Creek

The metric for this impairment is a measure of Deformities, Eroded fins, Lesions and Tumors (DELTs.)
The delisting target for this BUI is an average DELT value of 3% or under (1.3% in wading sites) AND, in areas where brown bullhead are present, the liver tumor prevalence rate cannot be higher than 5%.

Analyzing the scores with attainment levels in mind, the average DELT value is close to .0000% for the subwatershed. This number was derived from the DELT sampling data from 2013-14.

However, a sample done to test for liver neoplasms in brown bullhead catfish at the nearshore area of Euclid Creek, showed a 12.5% prevalence rate in 2013, indicating that this BUI is not yet delistable and more monitoring is needed.

BUI 6 - Degradation of Benthos in Euclid Creek

The delisting target for this BUI is an ICI score of 30 as outlined in the OhioEPA Delisting Guidance Document (34 in lacustuary). The average of scores in Euclid Creek is 9% above delisting target levels for this BUI in the entire HUC12. This Lake Erie Tributary’s benthic community is in good shape, bringing it within attainment numbers for delisting BUI 6. The high percentage is encouraging and further monitoring showing an upward trend should contribute to delisting.

BUI 8 - Eutrophication or Undesirable Algae in Euclid Creek

This BUI's metrics are under revision, so that information is unavailable at this time. Clarification is expected shortly, at which time the status will be reportable.

BUI 10 - Beach Closings / Recreational Contact

This BUI’s delisting targets require that beach advisories due to bacterial contamination be issued no more than 10% (fewer than 19 days) of the recreation season. The target must be met in 3 out of the 5 most recent years.

This BUI can also be considered restored when bacterial impacts from Combined Sewer Overflows (CSOs) are being addressed under a long term control plan where CSOs are the primary cause of impairment. The Northeast Ohio Regional Sewer District currently is operating under a long term control plan, including gray infrastructure in the form of retention tunnels throughout its sewershed as well as green infrastructure (as short term control while the infrastructure is built).

We will be studying what that means for attainment with regard to delisting, and whether reducing CSO discharges along actually results in reducing bacterial contamination to a level that reduces beach closings.

Currently, the beach-closing metric has been met in only 1 of the last 5 years.

BUI 11 - Degradation of Aesthetics in Euclid Creek

The Aesthetics BUI is primarily targeted at "observed ongoing occurrences of sludge deposits, oil sheens, scum and other objectionable materials; specifically materials that produce color, odor, or other nuisances."

The delisting guidance allows for removal of this BUI if CSOs are a "significant" cause of this impairment, and, in such cases, if short- and long-term measures are undertaken.

Euclid Creek is affected by the NEORSD’s CSO discharges of raw sewage. NEORSD has taken measures, and is taking further measures, to ensure the reduction of CSO discharges to streams in its sewershed.

Short term measures include Green Infrastructure and low-energy treatment options, providing improvements while the long term large-infrastructure plan is executed.

Therefore, removing this BUI could be expedited with an evaluation of the significance of CSO discharges to the impairment, and use of the control plan criteria.

BUI 14a - Loss of Fish Habitat in Euclid Creek

The delisting targets for this BUI are QHEI scores of both 55 for lacustuary and 60 for wading/headwaters as outlined in the OhioEPA Delisting Guidance.

The scores average is 9% above delisting target levels for this BUI in the entire HUC12. This Lake Erie tributary’s fish habitat is in good shape, bringing it within attainment numbers for delisting BUI 14a.

Even with the higher QHEI scores, there is a lot of opportunity for restoration to bring these numbers even higher. This will give us more confidence for the long term success of the fish habitat in Euclid Creek, considering that the watershed is heavily urbanized. This subwatershed is within attainment numbers for delisting BUI 14a.
