22 Habitat Parameters 2 Sand Gravel Mud Hard-pan clay Clay

23 Habitat Parameters 2 Gravel = bigger than a bb, but smaller than your fist Sand = sediment with particle sizes smaller than a bb but still with gritty texture Mud = silt and clay mixture Clay = sediment with particle sizes that will form ribbons when rubbed between thumb and fingers Hard-pan clay = compacted clay deposits on a stream bottom that give the appearance of bedrock, but have a hard gummy surface Gravel = bigger than a bb, but smaller than your fist Sand = sediment with particle sizes smaller than a bb but still with gritty texture Mud = silt and clay mixture Clay = sediment with particle sizes that will form ribbons when rubbed between thumb and fingers Hard-pan clay = compacted clay deposits on a stream bottom that give the appearance of bedrock, but have a hard gummy surface

24 3

25 Habitat Parameters 3

26 Mix = well-balanced combination of all four pool types present in the reach Deep/shallow = very dependent on watershed size; deep at the beginning of a stream may be only 0.5 meter, and deep in a larger stream may be one meter or more Mix = well-balanced combination of all four pool types present in the reach Deep/shallow = very dependent on watershed size; deep at the beginning of a stream may be only 0.5 meter, and deep in a larger stream may be one meter or more

27

28 Habitat Parameters 4 Point Bar Island

29 Habitat Parameters 4 Point bar = a curved ridge of sediment deposited by a stream on the inside of a bend (can be located below the surface of the water or extend above it)

30

31 Habitat Parameters 5 Base of lower bank = the point at which the stream bed ends and the stream bank begins

32 Habitat Parameters NOTE: = Parameters six through ten should evaluate an area from approximately 100 m upstream of (and in addition to) the original 100 m sampling reach (for a total of 200 m). This whole area should be evaluated as a composite. 200 meter reach original 100 meters additional 100 meters

33

34 Habitat Parameters 6 Dredging = physical removal of material from stream bed, usually done with heavy equipment Embankment = a stream bank that has been raised to hold back water, carry a roadway, etc. Bridge abutment = a structure that supports a bridge and is built in or near the stream Gabion = a metal cage containing natural materials (usually rock) that are stacked to support stream banks Dredging = physical removal of material from stream bed, usually done with heavy equipment Embankment = a stream bank that has been raised to hold back water, carry a roadway, etc. Bridge abutment = a structure that supports a bridge and is built in or near the stream Gabion = a metal cage containing natural materials (usually rock) that are stacked to support stream banks

40 Habitat Parameters 8 through 10 are scored for each bank Which bank is left and which is right?

41

42 Habitat Parameters 8 Erosion = loss of soil or rock material from the stream bank due to the flow of water Bank Failure/Sloughing = events that cause large scale displacement of soil or rock material due to support material being undercut or weakened by erosion due to saturation “Raw” areas = stream bank locations with recently exposed soil Erosion = loss of soil or rock material from the stream bank due to the flow of water Bank Failure/Sloughing = events that cause large scale displacement of soil or rock material due to support material being undercut or weakened by erosion due to saturation “Raw” areas = stream bank locations with recently exposed soil

47 Habitat Parameters 10 Optimal width is around 18 meters = ~60 feet

48 Habitat Parameters 10 Riparian area = the land along and adjacent to a stream or river

49 Field Data Sheet Completion Add the scores from parameters 1-10 on your Field Data Sheet (both sides) to determine your Total Habitat Score This step does not have to be completed at the stream Add the scores from parameters 1-10 on your Field Data Sheet (both sides) to determine your Total Habitat Score This step does not have to be completed at the stream

50 Field Record Completion At the stream, record the time and date that you perform your Habitat Assessment DateTime

51 Field Record Completion At the stream, complete: (1) Land (1) Land Uses Uses in the in the Watershed Watershed

52 Field Record Completion And, at the stream, complete: (2) Riparian Vegetation and and (3) Instream Features

53 Field Record Completion Transfer the Total Habitat Score from the Field Data Sheet to the box labeled “Total Habitat Score” on your Field Record

54 Field Record Completion Determine and record your headwater or wadeable classification in the box labeled “Headwater/Wadeable” These classifications are based on the watershed size (or area) measured from your sampling location

55 Field Record Completion Determining Headwater/ Wadeable Classification From the Watershed Watch Data Management page URL: http://eppcapp.ky.gov/watershed/ http://eppcapp.ky.gov/watershed/ Use the “Watershed Use the “Watershed Watch Site Locations” Watch Site Locations” link to determine your link to determine your site’s latitude and site’s latitude and longitude longitude

56 Field Record Completion Determining Watershed Size Use the “Kentucky Watershed Viewer” URL: http://gis.gapsky.org/watershed/ http://gis.gapsky.org/watershed/ to locate your to locate your sampling site sampling site using the using the “Find an Address” icon icon

57 Field Record Completion Determining Watershed Size Using the “Kentucky Watershed Viewer,” click the yellow line click the yellow line to determine to determine “SQMI:” “SQMI:” (watershed size in (watershed size in square miles) square miles)

58 Using the watershed size (“SQMI:” area), classify your watershed area as: <5.0 square miles = Headwater <5.0 square miles = Headwater OR OR >5.0 square miles = Wadeable >5.0 square miles = Wadeable Record the square miles (“SQMI:”) and Classification on your Field Record Field Record Completion Determining Headwater/Wadeable Classification

59 Using your Total Habitat Score, Bioregion, and Headwater or Wadeable classification, determine on Table 2 the Habitat Rating for your site and record in the box labeled “Habitat Rating” on your Field Record Field Record Completion

60 Following each Habitat Assessment event, please mail a copy of all completed forms to: KY Water Watch Office 200 Fair Oaks Lane, 4 th Floor Frankfort, KY 40601 Watershed Watch forms are maintained by the KY Water Watch program and electronically filed for safekeeping If you have any questions or difficulties, please contact the KY Water Watch office at: 1-800-928-0045 FORM SUBMITTAL

61 The Watershed Watch Stream Habitat Assessment examines the condition of ten habitat parameters to make supporting conclusions about the health of the aquatic system. INTERPRETATION

62 INTERPRETATION Diverse macroinvertebrate community Undisturbed riparian habitat High quality instream habitat

63 Disturbed riparian habitat Altered instream habitat INTERPRETATION Less diverse macroinvertebrate community

64 Typically shallow and narrowTypically shallow and narrow Direct influence by adjacentDirect influence by adjacentwatershed Watershed disturbance leadsWatershed disturbance leads to rapid, extensive stream impacts Headwater Typically wider and deeperTypically wider and deeper Also influenced by multiple headwater watershedsAlso influenced by multiple headwater watersheds Watershed disturbance effects buffered/magnified by multiple headwater watershedsWatershed disturbance effects buffered/magnified by multiple headwater watershedsWadeableINTERPRETATION
