Loading Analysis Plan and Supporting Data Acquisition Needed for the Tenmile Creek and the Ottawa River Watersheds Fulton and Lucas Counties, Ohio Total Maximum Daily Load Development Hill Ditch near mouth, Ottawa River (Toledo) basin. Ohio EPA Technical Report AMS/2011-OTTEN-3 Division of Surface Water Assessment and Modeling Section March 2019 TMDL DEVELOPMENT | AMS/2011-OTTEN-3 Loading Analysis Plan – Tenmile Creek and Ottawa River Watershed March 2019 Introduction This document provides an overview of the information considered in proposing analytical methods to address water quality impairments in the Tenmile Creek and Ottawa River watershed (Fulton and Lucas Counties, Ohio). These recommendations are based on data collected as part of a biological and water quality study in 2011. A description of the project area, sites, data types and methods can be found in the Tenmile Creek and Ottawa River study plan document at (https://epa.ohio.gov/portals/35/tmdl/TenmileStudyPlan2011_Final.pdf). A summary of the study results can be found in the biological and water quality report at (https://epa.ohio.gov/Portals/35/documents/Tenmile_Ottawa_TSD_2015.pdf). Sites in the Tenmile Creek and Ottawa River watershed were assessed for aquatic life use and recreation use. The public water supply use was not assessed since no surface waters are used as a public water supply in this study area. The attainment of aquatic life and recreation use is based on specific restoration targets. This document examines those targets and lays out proposals for addressing each impairment. Where appropriate, methods are outlined to develop total maximum daily loads (TMDL) for specific pollutants. Aquatic Life Use Evaluation of Biocriteria Attainment of Ohio EPA’s biocriteria are based on fish and macroinvertebrate scores, as measured by the Index of Biotic Integrity (IBI), Modified Index of well-being (MIwb) and Invertebrate Community Index (ICI). Goals for those indices in the Tenmile Creek and Ottawa River watershed are shown in Table 1. The attainment status for each site is shown in Figure 1 and the scores for impaired sites are shown in Table 2. Table 1 – Biological criteria applicable in the Ottawa River (Toledo) watershed for aquatic life use designations.

MWH-C (due to channelization) is listed first and MWH-I (due to impoundment) is listed second. 5 Limited to sites with appropriate conditions for artificial substrate placement. 2 AMS/2011-OTTEN-3 Loading Analysis Plan – Tenmile Creek and Ottawa River Watershed March 2019 Figure 1 — Map summarizing ALU attainment status in the Tenmile Creek and Ottawa River watershed in 2011. 3 AMS/2011-OTTEN-3 Loading Analysis Plan – Tenmile Creek and Ottawa River Watershed March 2019 Table 2 – Aquatic life use attainment information for impaired sampling locations in the Tenmile Creek and Ottawa River watershed, 2011.

B Boat site (large or deep waters, necessitating the use of boat sampling methods) Proposed Actions Ohio EPA considers many factors when deciding how to address impairments. For some projects, no TMDL is required. The watershed may be in attainment or the impairment is being addressed by another program/entity so no further action by the Division of Surface Water is necessary. Additionally, the cause of impairment may be natural (i.e., flow or habitat), in which case no action is required. For those needing a TMDL, the complexity of each impairment—including the primary origin of the pollutant, its delivery mechanisms and the waterbody kinetics involved—will determine the complexity needed in a model.
