The water in Spa Creek is being tested in seven locations every Thursday morning, rain or shine, throughout the summer and twice monthly in September and October. The following water quality factors are among the values being tested:Spa Creek water is tested every Thursday morning at eleven locations on the creek. Red indicates unsafe swimming levels.
2018 begins the third year that there has been regular water testing on Spa Creek. May 3 was the first testing of the year and beginning May 24 the testing will be weekly. The map below shows all eleven sites being tested in 2018
2018 Water Testing
June 21
Average water temperature is now 78.8 degrees. That's up nearly 6 degrees from last week. And the rain has made the more shallows areas of Spa Creek unsafe for swimming. Red points on the map below indicate unsafe levels of bacteria.
June 14
Average water temps in Spa Creek now at 73 degrees. Water samples taken on Thursday show unsafe levels of bacteria at the Children's Museum bridge and the footbridge at the end of So. Cherry Grove. Everywhere else tested within safe swimming range.
May 31
Samples taken before the rain. Anne Arundel County recommends staying out of the water for 48 hours after a rainfall.
May 24
High levels of bacteria in shallow areas of Spa Creek, including the Chesapeake Children's Museum, around Truxtun Park and Hawkins Cove and at the end of So. Cherry Grove. Water temperatures is now at an average 71.6 degrees.
2018 begins the third year that there has been regular water testing on Spa Creek. May 3 was the first testing of the year and beginning May 24 the testing will be weekly. The map below shows all eleven sites being tested in 2018, and the first time since testing began that enterococci levels are at acceptable levels at each testing site. The water temperature is averaging 60 degrees throughout the creek.
The 2017 fall testing scheduled, implemented in September, went from weekly testing to twice per month.

Aug 1: Restoration work began on the headwater section of Spa Creek that runs under the bridge at the end of S. Cherry Grove and may effect the results.
July 27: Bacteria levels climbing into unsafe levels around Truxtun Park. With heavy rain on the way stay out of the water for at least 48 hours after the rain stops.
July 20: The water temperature in Spa Creek is now at an average of 84.65 degrees F. This isn't surprising since we've all been smoldering in the heat but that's up nearly 2 degrees in the last week and could mean an increased chance for algae blooms. The water at South Cherry Grove and the Children's Museum has very high levels of unsafe bacteria. Stay out of the water in those two areas.
July 6: The only place with safe bacteria levels this week is at Capital SUP, all other areas are unsafe to swim in. After heavy rain on Thursday it is best to stay out of Spa Creek for at least 48 hours.

June 29 results: The only spot with unsafe bacteria levels this week is at the footbridge at the end of South Cherry Grove. Clean up of trash and debris around the Children's Museum and Silopanna is nearly complete. It's a holiday weekend and warm temperatures, perfect for being on the water but remember, if it rains stay out of the water for 48 hours.
June 15 results: There are unsafe bacteria levels at the foot bridge near the Chesapeake Children's Museum, where phragmites removal is about completed, and at the end of South Cherry Grove. Total suspended solids (TSS) are too high at all locations, except So. Cherry Grove, to allow for subaquatic vegetation to grow and survive.
June 8 results: Unsafe bacteria levels in Hawkins Cove (across from the Truxtun boat ramp), Chesapeake Children's Museum and at the end of South Cherry Grove. The project to remove phragmites near the Children's Museum is likely the cause of increase enterococci levels at that location.
June 1 results: Bacteria levels are back within safe ranges except near the headwaters and Silopanna where work is being done to pull out phragmites and create swales upstream.

Testing began on Thursday, May 11, 2017 and will continue weekly beginning May 25th. Results should be available on Friday afternoons.
Anne Arundel County, and many other agencies, recommend not swimming in the water for 48 hours after a rain event of 0.5 inches or more, especially for those that are immune-suppressed and those with open wounds.
Results show Enterococci levels, the bacterial measurement that is an indicator of fecal contamination (found in the gut of all warm-blooded mammals and a number of birds including geese and ducks).

Fall 2016
Testing has moved from a weekly schedule to monthly for the fall and winter
Oct 13: No sample taken at Ego Alley because access was restricted due to the boat show. Chesapeake Children's Museum and South Cherry Grove had unsafe levels of enterococci.

Sept 29: With heavy rains falling within 24 hours of collecting water samples, all of the sites showed very high and unsafe levels of enterococci. In addition pH levels dropped below what is considered healthy for marine life in our waterways. This is the last testing to be done on a weekly basis until next summer. Spa Creek Conservancy will now switch to bi-monthly testing. Check back to see what happens to the creek during colder seasons.
+ Rain event within 24 hours of testing
Sept 22: Safe swimming levels in Ego Alley, Capital SUP and Hawkins Cove.
Unsafe levels were measured at the end of South Cherry Grove Avenue in Annapolis, and at the bridge by the Chesapeake Children's Museum. The high limit for water that is regularly used for swimming is 104 cfu/100 ml.

The Total Suspended Solids (TSS) are 2 times higher in all parts of Spa Creek than what is needed for SAV growth and survival.
Dissolved oxygen (DO) at Hawkins Cove is near the levels where the cove area is considered very hypoxic. Dissolved oxygen is necessary for the survival of many marine animals.
pH levels at Hawkins Cove are also high and at levels that will not permit marine life.
