Open Water Sampling

The Fishers Health and Water Quality programs are working together to provide our residents and guests open water information in Fishers. We have several waterways where enthusiasts enjoy swimming, boating, kayaking, fishing, and other water sports. We are fortunate to have flowing creeks, White River, Saxony Beach, and Geist Reservoir to enjoy. We also have private open water areas neighborhood residents enjoy such as Lake Stonebridge. 

Our largest open water gathering spot is Geist Reservoir. Geist was constructed in 1943 by damming Fall Creek to provide water to the Indianapolis area.

Our Water Quality division has 40 creek and open water locations they test. We have selected 9 areas that will be published monthly during the Spring, Summer and Fall seasons where we find our residents enjoying those waterways most. We will be posting the following results:

Water Temperature

Aquatic organisms thrive in warmer water. Bacteria also grows faster at higher temperatures. Higher temperatures combined with sediment from agricultural waste or leaking septic tanks during a rain event can increase the pathogenic bacteria levels such as E. coli. Fishers has both urban and agricultural runoff inputs into the watershed which affects our water quality. Learn more.

Dissolved Oxygen (DO)

DO is essential for aquatic life. Low levels of oxygen (hypoxia) or no oxygen (anoxia) can occur when excess organic materials, such as large algal blooms, are decomposed by microorganisms. During this decomposition process, DO in the water is consumed. Low oxygen levels often occur in the bottom of the water column and affect organisms that live in the sediments. In some bodies of water, DO levels fluctuate periodically, seasonally, and even as part of the natural daily ecology of the aquatic resource. As DO levels drop, some sensitive animals may move away, decline in health or even perish. (U.S. EPA) Moving or flowing water, like streams, tend to have more DO than a lake or pond. Details.

E. coli

Wherever you have humans or wildlife in contact with water, you have the potential for waterborne disease. Since E. coli is a naturally occurring bacteria found in warm-blooded animals, it is used as an indicator for other harmful bacteria and viruses in the water environment. Humans naturally affect water quality by land use practices (agricultural, residential, wastewater etc.), recreational use (swimming, fishing, boating etc.), and drinking water withdrawal and treatment. Major waterborne diseases include dysentery, Hepatitis A and bacterial and viral gastroenteritis (E. coli). Monitoring for these bacteria is a vital component to public health. While fecal coliform, E. coli, does not necessarily cause disease, it is an indicator of disease-causing organisms. Learn more.

Algae

We are not able to test for Algae. IDEM is one of the few locations that do, they however are only able to test designated state locations. Citizen’s water does tests different types of algae and have agreed to notify your Fishers’s Health Dept. in cases of problematic concerns. Notification will be made at that time.

We are developing a notification procedure that will be available shortly. A social media post will notify residents when it is available.You will have the opportunity to be notified when unsatisfactory samples are obtained in areas listed above other than Geist Park and White River. Their results will still be submitted however please read our public notice regarding those 2 locations.    

Public Notice  

Frequent unsatisfactory levels at Geist Park and White River are a result of our waterways being in the Upper White River Watershed.  We receive both urban and agricultural run-off during high rain events.   Besides the farmland and older septic systems upstream, our urban and suburban expansion areas are rapidly increasing making it particularly susceptible to anthropogenic influences related to both agricultural practices as well as effects of urbanization (IUPUI). Surface waters are directly affected by these various sources of contamination carrying E. coli into the watershed. The more vegetated areas with grasses tend to soak up rainfall, directly increasing infiltration into the ground and reducing run-off into our recreational waterways. Land that has been developed with streets, roof tops, sidewalks, driveways, and parking lots are impervious and create run-off into storm drains that eventually lead to our waterways. In the agricultural areas run-off can come from fields and animals. Heavy rain events wash manure from land into the waterways. An increase of E. coli is generally seen after these rain events as well as when water temperatures rise. E. coli is adapted to living in the intestines of warm-blooded animals, so it naturally thrives in warmer temperatures. Point source discharges such as septic system failures, storm water outfalls and wastewater treatment plant overflows also directly input E. coli into recreational waterways.  

We added an additional water sampling location on Fall Creek as it enters the reservoir east of the Olio bridge, (Fall Creek at Canal Place).  Here we are better able to compare water quality as it enters the reservoir. We again test it at the Olio Rd. boat ramp as it flows south further into the reservoir, along with added sampling in “Family Cove” and “Cambridge Cove”. These samplings will have direct relation to where we find most relaxing in the water.
