Started using pH meter instead of test strips, reading is 8.1, substantially higher than test strips. Have now deleted pH value as I suspect the meter was incorrectly calibrated.
Previous day: heavily turbid water during heavy rains. Suspected erosion from construction site (Harry Jerome construction). In the past month, there have been multiple contamination events: cement wash 3 weeks ago and laundry soap one week ago.

Spill noted, reported to CNV.
High pH value - off the scale of WR chart. Estimate about 10. For comparison, tested pH and water hardness downstream; pH downstream was 8.4, alkalinity/water hardness had lower values. Relayed to CNV that concrete contaminiation suspected.
Update: Source of spill identified. Concrete overpass being taken down on 23rd St for new community centre. Concrete slurry was making its way into storm drain.

heavy rain last 2 days. catchment was salted due to freezing in past week.
some invasives coming back to the pool edge.

**did the test strips 2x and took average of the 2 tests for alk and hardness. as 1st test was read too quickly.

City has cleared out most of the blackberry that used to surround part of the area around the storm pipe.

Water is stagnant. Unpleasant odor like animal feces. Very low water level. Lots of water strider insects.

Small trickle from pipe. The pool is very small (mostly evaporated).
