  1. Kaleidoscope Charter School Elm Creek Watershed Management Commission Hennepin County Rush Creek Site #4 May 18, 2011 Spring 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:15 CAir Temperature:20 C

  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 2 Snags and logs 1 Aquatic vegetation beds 1 Silt/Sand/Gravel substrate 4 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 # • 10.88seconds 20 feet • 11.06seconds 20 feet • 11.03seconds 20 feet • 9.66seconds 20 feet • 12.37seconds 20 feet Average Time of Travel= Total Time divided by # of measurements 11 seconds Velocity= Distance divided by Average Time1.81 ft or meters/sec.

  9. River Bottom Composition and Embeddedness Average Embeddedness Average Embeddedness for the site: TOTAL (add all 10 together) 245/10=24.5%

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

  11. What the findings mean to the watershed The macro-invertebrates we found and identified have a low to medium tolerance level. We found 179macro-invertebrates in the range of 0 to 5 tolerance level. We found 15 macro-invertebrates in the range of 6 to 10. With the high level of snow received this winter and the numerous inches of rain this spring there was a lot of sediment in our testing area. Because of the rushing water, lower tolerance of the majority of our bugs, and clear, scentless water our water quality is on the healthier side.
