Depth, Dredging & Dock Update - On the Eve of Spring Launch


March is nearly behind us, now, and it’s time to get our launch season underway.

One of the most-talked-about off-season topics has been the loss of Lake Michigan water and how that affects boaters here at Pier 33, in and around the St. Joseph harbor and through Michigan and the Great Lakes.

Pier 33 recently hosted a public forum, March 16, during our Spring Open House. Thank you to all who attended. The forum featured presentations by Michigan State Representative Al Pscholka, John Gruchot from Berrien County Community Development and Kim Fish, Assistant Division Chief, Water Resources Division, Michigan Department of Environmental Quality. I also had an opportunity to fill boaters in on Pier 33’s outlook and plans for the coming season. Our presenters arrived with plenty of helpful information and the attending boaters had lots of great questions. Hopefully, we were able to provide enough information to the group to help boaters understand the current conditions, anticipate what may occur during the season and plan to adapt as needed for the summer of 2013.

Our dry summer in 2012 and a succession of warmer-than-usual winters brought a noticeable loss

of water under everyone’s boat by the end of the 2012 season. Water levels usually do drop as we get into the fall, but this was quite a bit more than usual. It became a longer climb down to the gunwale, dock lines got tight and in some marinas, boaters were bottomed-out or had difficulty accessing ramps or haul-out facilities.

We’ve kept a careful watch during the off-season on regular forecast updates provided by the U.S. Army Corps of Engineers. As of today’s date, Lake Michigan is 15 inches below its level of one year ago and is forecasted to rise 3 to 4 inches over the next month. 

Here is a link to great data provided on-line by USACE: Click Here.

For navigation purposes, the level of the Lake itself isn’t that critical to our recreational boaters … until it impacts the depth of the rivers & channels. As the Lake lowers, so do its tributaries. As the level of the St. Joseph River and Morrison Channels has dropped right along with Lake Michigan, sandy shoaled areas become more prevalent and dangerous, in some places strangling access to the lake, launch ramps and marinas.

In early March, Pier 33 commissioned a professional survey of a critical area of Morrison Channel, extending roughly from our gas dock down river to the edge of our showroom parking lot. That’s the same area where Pier 33 has traditionally maintained depths to allow safe passage for our own boaters and neighboring boaters upriver. The data is plotted on an overlay of Morrison Channel that looks like the photo shown here. With the plotted depths so close together and in the size they are printed, this can only be read in a super-enlarged version. A 4’ x 6’ reproduction of this photo is on display at Pier 33 now. In general, the photo will show nearly all key depths above 4’ feet and most in the 6 to 7 foot range, with the exception of the “Boathouse” side of Morrison Channel and areas upriver of our gas dock. The deep-water area at our gas dock does only extend approximately halfway across the Channel – within the area where Pier 33 is permitted to dredge.

Before you begin your boating season on Morrison Channel, I would encourage you to visit our office and have a look at the enlarged survey photo, so that you can boat confidently in areas of the Channel where there is ample depth and also be aware of areas you should stay clear of.  If you would like to have this photo file for your own review, please contact me via e-mail and I will send it to you.

This survey was performed when the surface level of Morrison Channel was 576.7 above sea level. This is an important benchmark, as it allows us to provide daily updates throughout the season that show how much – or how little the Channel has risen or fallen. Watch for more information about those updates – we will be posting daily via Twitter once the season is really underway. I hope those updates will be helpful to you.

After analyzing our March 4 survey, we concluded that there is no dredging required now within Pier 33’s permitted dredging area. Depths are apparently sufficient for safe navigation, although there are a few isolated lower spots (just below 4 feet per the survey). As the Lake level increases during the summer, we should see this area of the Channel remain navigable to most powerboats.

We will continue to monitor the changing level of the Lake and Morrison Channel throughout the boating season and this blog will be a good place for you to check in for that updated information. Likewise, as mentioned, be on the lookout via our Twitter feed: www.twitter.com/pier33marina for daily Channel level updates as the season gets going.

In 2005 and 2006, Pier 33 completely replaced all docks at our South and East marinas with adjustable steel docks designed by Donkersloot & Sons of New Buffalo, MI. These docks can be raised and lowered, seasonally, to accommodate changing levels. Next week (week of April 1), the Donkersloot crew will be in town to drop each dock area either one (7.5”) or two (15”, where possible) notches. This will adjustment will offset some of the water loss, make it safer and easier for our boaters to board and will also bring the underside dock pilings lower to the water, providing better
protection for each boat and helping prevent slide-unders. Our staff has also rigged a new gizmo that will be undergoing tests during our launch season, aptly named the “Gelcoat Damage Reducer”. It’s a simple PVC and rope rig that will cap the bottom of the outermost dock piling. These are available for sale at our Ship’s Store and can be self installed, or you can fabricate your own. See Greg Belanger. Please do not bolt or screw any fenders, boards or others materials onto the docks – lines or straps, only.

Be aware in advance, please, that lowering the docks will increase the slope of the adjustable steps. It will be a slightly greater incline. Please be patient and get used to the new feel.

Now, let’s swing back to dredging and future plans. Pier 33 has always maintained Morrison Channel on a self-funded basis, with our own permits and under our own direction. We currently have a valid permit to continue dredging as needed. During the past few months, Berrien County Community Development has spearheaded an effort to create a system of riverfront assessment districts that will allow a bond to be issued and then repaid by property owners (including all of the affected marinas such as Pier 33) for dredging the St. Joseph River and Morrison Channel. Pier 33 fully supports this effort by Berrien County – and it’s not an easy project to bring together. A healthy recreational boating community throughout St. Joseph and Benton Harbor is good for all of us – marina operators, boaters and the community at large. This plan by the County is at no cost to the taxpayers beyond the assessment districts.

Unfortunately, despite urgent efforts and excellent cooperation among all involved, this project is a ways off. If and when the County’s broad-project permit is issued, any property holder can use that permit independently (with the County’s permission) to get dredging underway at there own expense. The final pieces of the process – assessments defined, all municipalities agreed, funding in place and a dredge in the river – will not likely arrive until late summer and that will not provide relief for many of our neighboring boaters. Yet the ultimate goal of having navigable channels all around our island is worthwhile and important – so please be patient and supportive of the County’s efforts.

The coordination of this comprehensive dredging approach should bring us some better economies of scale, reducing the overall cost per cubic yard and thereby allowing marinas such as Pier 33 to hold down the pass-along costs that must ultimately occur. We want to keep boating as affordable as possible for our boaters. Between 2000 and 2013, Pier 33 spent nearly $1 Million to maintain Morrison Channel, including nearly $200k in 2012. Those costs are rising with each dredging occasion, including engineering, permitting, removal and disposal.

For the Summer of 2013 – and certainly beyond – we’re glad to accommodate boaters who don’t yet have the advantages found at Pier 33 right now. We have ample water, great docks, a friendly atmosphere, a short ride to the Lake, multiple convenient services such as Launch on Command, Hook ‘n Go, Mobile Pump Out, certified technicians and extended hours. As of this date, we do have some dock openings, but those are closing quickly. We would be glad to have you with us if it’s time for a change.

Feel welcome to comment here or to contact me with any questions that we can help with. Happy Boating in 2013.
