Turkey Creek — Palm Bay, Florida

Turkey Creek is a tidal creek in Palm Bay whose USGS gauge lists a 105 square mile drainage area, and it meets the Indian River Lagoon between Castaway Point and Palm Bay Point.

The federal gauge on the creek, USGS 02250030 Turkey Creek at Palm Bay, FL, is classed as a tidal stream, sits in the Cape Canaveral hydrologic subbasin, and has a data record that begins on January 14, 1981 (USGS Water Data). The City of Palm Bay sends residents to that same gauge for real-time levels on its flood information page (City of Palm Bay flood information).

Palm Bay Public Works says the majority of water in Palm Bay reaches the Indian River Lagoon through Turkey Creek or via direct discharge (City of Palm Bay stormwater). The 1982 manatee report on the creek adds that Turkey Creek empties into the Indian River after widening into a small bay (1982 Turkey Creek manatee report).

The state draws the mouth precisely. Florida's manatee rule for Brevard County fixes the downstream end of Turkey Creek on a line from the southeasternmost point of Castaway Point to the northeasternmost point of Palm Bay Point, and the upstream end of its protected reach at Melbourne-Tillman structure MS-1 (Rule 68C-22.006).

The Melbourne-Tillman canal system turned Turkey Creek into the outlet for a much larger drainage area: its outlet canal was connected to the creek in 1924, and by 2005 the C-1 canal supplied over 90% of the freshwater leaving through the creek.

The 1982 Turkey Creek report records that in 1924 the outlet canal of the Melbourne-Tillman Water Control District was connected to the creek, and that the 200 mile system of canals had become the major input into the creek (1982 Turkey Creek manatee report). Today the district says it contains 100 square miles, including portions of unincorporated Brevard County, the City of Palm Bay and the City of West Melbourne, and maintains 163 miles of canals (Melbourne-Tillman Water Control District).

The effect on water quality was spelled out in a 2005 St. Johns River Water Management District budget request for the Indian River Lagoon Initiative, which listed the C-1 Rediversion, Turkey Creek Basin as a subproject. It stated that over 90% of the annual volume of freshwater and 68% to 80% of the annual loads of nitrogen, phosphorus and suspended solids discharged through Turkey Creek came from the C-1 canal, and that these flows affected seagrasses in a 10 to 20 square mile area of the lagoon (Florida Senate, FY 2005-06 request). The C-1 Rediversion target was a cut of 50% or more in suspended solids, nitrogen and phosphorus into Turkey Creek and the lagoon.

The rediversion then moved water west. The St. Johns River Water Management District reported on May 11, 2017 that upgrades let the Melbourne-Tillman Water Control District pump up to 39 percent of average annual stormwater to Sawgrass Lake, potentially an average of 27.5 million gallons a day, toward the St. Johns River instead of east to Turkey Creek. The 2017 work recontoured the banks along a mile-long stretch of the C-1 Canal in Palm Bay (SJRWMD).

The mouth of Turkey Creek is where Palm Bay began: in 1870 a citrus partnership bought 75 acres on the Indian River and shipped fruit from Tillman's Wharf, now Castaway Point, and a Catholic colony settled the same ground after 1911.

The National Register nomination for Palm Bay's Historic St. Joseph Catholic Church tells the story. John Tillman, J.B. Creech and M.J. Culpepper formed Culpepper, Creech and Co. in 1870 to buy a 75 acre tract along the Indian River for citrus groves, and their packing house stood at Tillman's Wharf at the mouth of Turkey Creek, where fruit was loaded onto sailing craft and steamboats bound north (National Register nomination).

Tillman got a post office on March 4, 1887, and the area became the Town of Tillman, though the nomination counts only 40 residents and no elected officials. The Florida Indian River Catholic Colony received a state permit on July 21, 1911, and families from Indiana, Wisconsin, Kansas and Oklahoma began arriving in 1912 on the Florida East Coast Railway (National Register nomination).

A 2018 state historical marker at 1422 Miller Street in Palm Bay places that settlement on the creek itself: by 1914 the land company had helped settle nearly 100 midwestern families, mostly of German and Slavic descent, in the area of Tillman on the banks of the Indian River and Turkey Creek (Florida Historical Marker).

Turkey Creek holds manatees, alligators and Florida cooters, with otters and gar also possible, and manatees have used the Palm Bay creek for decades, from at least the 1960s.

The City of Palm Bay lists manatees, alligators and Florida cooters in the creek along the Turkey Creek Sanctuary, with an otter or a gar fish possible (City of Palm Bay, Turkey Creek Sanctuary). Manatees are the creek's best documented residents.

The 1982 report notes that herds of manatees in Turkey Creek have been reported as early as the sixties, that a 1979 study established manatee use of the creek from March through December, and that a 1979 study reported 700 manatee sightings and identified 33 different individuals using the creek that year (1982 Turkey Creek manatee report).

Boats are slowed for them today. Under Florida rule 68C-22.006, all waters of Turkey Creek downstream of Melbourne-Tillman structure MS-1 are an idle speed zone all year, out to the line between Castaway Point and Palm Bay Point (Rule 68C-22.006).

Palm Bay's Turkey Creek manatee program dates to 1979-80, when the city served as the model for a Coastal Zone Management grant manatee program, and in 1982 it named the manatee its Official City Animal and declared the creek a local critical area.

The report for state contract CM-36 says the City of Palm Bay served as a model for the development of a Model Manatee Protection Program for a Coastal Zone Management Grant in 1979-80, and that the 1982 project carried it out between January and October 1982 (1982 Turkey Creek manatee report).

The City Council acted twice that year. On March 25, 1982 it adopted Resolution 82-12 designating the manatee as the Official City Animal, and Resolution 82-11 declared Turkey Creek a local critical area for manatees. The Mayor proclaimed May 15, 1982 as Turkey Creek Day, and the 1982 Legislature amended the Manatee Sanctuary Act to direct rules on boat speeds in part of Turkey Creek (1982 Turkey Creek manatee report).

Public outreach was broad. The same report counts 34 presentations reaching 1,376 people, and Palm Bay sixth graders traveled to Tallahassee to make presentations to the Governor and circulated a petition that drew more than 8,000 signatures (1982 Turkey Creek manatee report). The city's current code still names the creek: Chapter 204 finds that poorly managed stormwater may interfere with the water quality and quantity of the Indian River Lagoon and Turkey Creek (Palm Bay Code, Chapter 204).
