If Hugh Willoughby had not been searching for a southern location for the prestigious New York Yacht Club in 1906, we would not have the remarkable hand drawn map above. The New York Yacht Club’s southern headquarters was never established at the southern tip of Sewall’s Point, but we can see the water depths in the area were substantial, at 20 feet, around the tip of the protected west side of today’s High Point subdivision.

I stumbled upon the information about the New York Yacht Club again, because of trying to track water depths in the St Lucie River/Indian River Lagoon over the past century in my mother’s book, The History of Sewall’s Point.

From my parent’s old timer friends, over the years, I have heard stories about the the water depth and clarity being extensive in many areas of the St Lucie River, from Palm City to Stuart to Sewall’s Point, and how over time the sediment, due to canal run off from C-23, C-24 and C-44, has “filled the bottom of the river” in many areas, even forming “islands” north of the Palm City Bridge. C-44, connected to Lake Okeechobee, was first connected in 1923, and then deepened and widened again in the 1930s, and 50s and “improved since.” C-23 and C-24 were built in the 50s and 60s. Tremendous amounts of sediment and pollution has filled the river over time from these once thought “harmless” canals.

Today this sediment fill is often referred to as “muck.”

Anyway, for a baseline comparison of water depths, I started looking thorough my historian mother’s maps and asking questions to my attorney brother, who is a wiz at any type of map old or new, and although I did not get mapping for all of the the St Lucie River/Indian River Lagoon, I did for my own beloved Sewall’s Point. I imagine it is a microcosm of the rest.

Let’s take a closer look:

NOAA, 2014 electronic water depth map juxtaposed to hand drawn map of Sewall’s Point ca. 1906.

Comparing the two maps, one can see that the southern tip of Sewall’s Point in the NOAA map is not documented, I imagine because it is too far away from the Okeechobee Waterway. Disappointing. Nonetheless, if one looks at Sewall’s Point’s mid area, across and north of Hell’s Gate (the narrow part of the river) one can see water depth numbers like 19; 15; and 14 feet. Today those numbers on the NOAA chart read 4; 8; and 7.

Looking on the Stuart side, north of Hell’s Gate, the 1906 map reads 10; 8 and 12 feet. The 2014 NOAA map reads 2; 3; and 4 feet. Mind you, the channel has been dredged many times by the Army Corp, and Florida Inland Navigation District since 1906 and this certainly affects depths overall in the river as well. Nonetheless, for me, it is interesting to compare as even the channel depths in this area are no deeper than 11 feet and often more like 8 or 6  feet.

The famous mid 1900s environmentalist editor of the Stuart News, Mr Ernie Lyons, once said “Life too, is a changing river.” I  wonder if he knew how much we were going to fill it in…

After I wrote this blog , friend, Kevin Stinnette, sent me the insert for south Sewall’s Point as he has experience as an avid sailer. I am adding for interest although I will not adjust my blog. The same principles hold true. 🙂 Thank you Kevin!
