Monitoring Site Description
• The place we go to monitor Little McAllister Creek is in our school neighborhood, in the Alpine Meadows sub-division. We can walk there, but we have to get someone to unlock the gate for us. On our walk, we pass many houses, yards, a small playground, some green open space, and several stormwater retention ponds.

Data Interpretation We think dog waste may be causing
a higher level of nitrates. Fertilizer from lawns might be another cause.
Our ideas to improve water quality at our site include:
• Encourage pet owners to pick up after their dogs, keep dogs from running loose, and walk dogs on a leash
• Encourage people to use less fertilizer, or practice organic methods of gardening.
