  1. Kaleidoscope Charter School Elm Creek Watershed Management Commission Hennepin County Rush Creek Site #4 September 29, 2011 Fall 2011 Data Time tested: AM

  2. In past 24 hours… Storm (heavy rain) Rain (steady) Showers (intermittent) Overcast Clear/Sunny Snowy Now… Storm (heavy rain) Rain (steady) Showers (intermittent) Overcast Clear/Sunny Weather Temperature ReadingsTaken in the shade Water Temperature:14 CAir Temperature:16C

  3. Water Appearance Water Odor Check one: • Clear • Blue-green • Green • Yellow • Brown • Milky • Check one: • None • Fishy • Musty • Rotten eggs • Septic

  4. Residential Commercial Agriculture Natural/Preserve Lawns Wooded Crop land Grazing land Feed lot Paved roads or bridges Unpaved roads Construction Recreational use Industrial Land fill Waste treatment plant Evidence of past alteration Local Land Useland use in local watershed within ¼ mile of site

  5. Check one: Rocky bottom Muddy bottom (Record the number of jabs taken in each habitat type) Vegetated bank margins 10 Snags and logs 24 Aquatic vegetation beds 11 Silt/Sand/Gravel substrate 25 Type of Sampling

  6. Stream DepthMeasure the depth across the stream, from right bank to left bank in one-foot intervals for a minimum of 10 measurements

  7. Stream Width3 measurements in feet

  8. Measuring Stream Velocity Trial # • 71seconds 20 feet • 59seconds 20 feet • 120seconds 20 feet • 277seconds 20 feet • 66seconds 20 feet Average Time of Travel= Total Time divided by # of measurements 118.6 seconds Velocity= Distance divided by Average Time0.168ft or m/sec.

  9. River Bottom Composition and Embeddedness Average Embeddedness Average Embeddedness for the site: TOTAL (add all 10 together) 312/10=31.2%

  10. # of Squares Counted: 6 Macro-Invertebrates Identified

  11. What the findings mean to the watershed The majority of the macro-invertebrates we found and identified have a medium tolerance level. We found 1 macro-invertebrate in the range of 0 to 5 tolerance level. We found 240macro-invertebrates in the range of 6 to 10. With the low level of rain received this summer, our stream’s velocity decreased compared to the spring data. Because of the lower velocity the higher number of bugs are able to stay in the stream.
