Opening Waters

Since we are almost halfway through March and the paddling season is nearly upon us, Dave Finck and I headed south on Highway 11 out of Sioux Falls this morning to check out some of the area waterways.

Big Sioux River Access Point at Grandview Bridge 

Our first stop was at the Grandview put-in, along the highway south that passes Lake Alvin.  The Grandview road is 272^nd Street, just north of the Lake Alvin turn-off and crosses the Big Sioux River.  The State of South Dakota maintains a boat access point just above the bridge.  Viewed both up and down stream, the Big Sioux is open, with large chunks of ice, some up to 1 ½ feet thick, scattered along the shoreline.  The water, of course, is ice cold.

Next, we stopped by Lake Alvin to see how the melt was progressing.  Water is flowing over the spillway, and the channel leading from the main body of the lake up to the spillway is open.  There is an open lead along the shore that extends out, but the main body of the lake is still ice covered.  It seems as though the ice can only last a short time now.  Last year at this time, I had already taken my first cruise on Lake Alvin.  So, I would think, the remaining ice will surely disappear within the next week or so.

Then we drove down to the Klondike Dam site to check how the removal process has progressed.  The major part of the dam removal work has been accomplished.  The equipment has disappeared from the scene, and the water is flowing through the rapids. The ice is mostly gone from the stream, although very large chunks of ice have moved downstream and are scattered along the banks. 

Rapids Upstream from Klondike Bridge Over the Big Sioux River

The water is moving fast through the slot created for the rapids.  We were able to talk at some length with one of the Lyon County (Iowa) conservation officers.  He told us that some of the large boulders in the stream have shifted and created more rapids than planned.  These large rocks will be repositioned soon.  The rural water supply people use water from the Big Sioux that is captured just above the bridge, where the old dam was situated.

Because of the need to maintain a rural water supply, the project developers needed to maintain a pool of deeper water above the dam to ensure adequate flow for their purposes.  This is, apparently, the rationale for creating a set of rapids that inhibits the water flow.  Another benefit of the work, obviously, is the removal of a potentially dangerous low-head dam across the Big Sioux River.

The conservation officer told us that South Dakota planned another boat launch ramp above the rapids.  On the Iowa side, more development is anticipated with an access point for the river and, over the long haul, cabins and camping facilities on that side of the river, both above and below the bridge.

At this point, a run through the rapids does not look very appealing to me.  I hope that a portage trail is developed soon so that longer cruises through this portion of the river will be feasible.  The rapids are certainly better than the low-head dam, but I just don’t feel a sense of ease in thinking about shooting through those rocks in the in the middle of the current flow.

Finally, I returned to the river bank an hour or so later with one of my sons and my wife for a hike
through the Gitchie Manitou State Preserve on the Iowa side of the Big Sioux River.  The water seemed totally free of ice at that point with a smooth flow downstream.  Geese were settling in along the river, perhaps beginning the nesting season.

So, the great meltdown is underway.  Very soon, this narrative will capture images and description of conditions on area waterways as our much anticipated spring begins.
