The First River Plans: Long Before “Above the Falls” and “RiverFirst”

“I have been trying hard all Winter to save the river banks and have had some of the best men for backers, but Satan has beaten us.” H. W. S. Cleveland to Frederick Law Olmsted on efforts to have the banks of the Mississippi River in Minneapolis preserved as parkland, June 13, 1889 (Letter: Olmsted Papers, Library of Congress. Photo: H. W. S. Cleveland, undated, Ramsey County Historical Society)

Considerable time, effort and expense—$1.5 million spent or contractually committed to date—have been invested in the last two years to create “RiverFirst,” a new vision and plans for park development in Minneapolis along the Mississippi River above St. Anthony Falls. That’s in addition to the old vision and plans, which were actually called “Above the Falls” and haven’t been set aside either. If you’re confused, you’re not alone.

Efforts to “improve” the banks of the Mississippi River above the falls have a long and disappointing history. Despite the impression given since the riverfront design competition was announced in 2010, the river banks above the falls—the sinew of the early Minneapolis economy—have been given considerable attention at various times over the last 150 years. There’s much more

Low River Redux

The dry weather this year is evident on the Mississippi River at St. Anthony Falls. A couple weeks ago I posted an aerial photo of St. Anthony Falls when it was very dry in 1955. The water levels on the river appear to be similar now. Larry Dillehay sent this photo taken on the afternoon of October 2. The concrete apron at the Falls isn’t quite dry, but there’s not enough water flowing to make a ripple at the bottom. The horseshoe dam above the falls is now completely out of the water. What a gorgeous day—again.

Postscript: Both the horseshoe dam and Lock and Dam #1, or Ford Dam, were repaired while the water was at this level, suggesting that while the summer had been very dry, the water levels had been lowered intentionally by the U.S. Army Corps of Engineers to facilitate mainteneance.

1955 Was a Very Dry Year

It’s not a common sight. I’d never seen it myself until I saw this picture from Fairchild Aerial Surveys taken in 1955. St. Anthony Falls is completely dry.

Water levels were down everywhere at the time. Meteorological charts list 1955 as the 13th driest year on record in Minneapolis, but a look at longer-term data reveal that rainfall had been below normal for most of the previous 40 years. Downstream from St. Anthony Falls, the river was also very low, revealing the former structure of the locks at the Meeker Island Dam.

The old lock structure from the Meeker Island Dam protrudes from the low water in 1955. The old lock and dam between Franklin Avenue and Lake Street were destroyed when the new “high dam” or Ford dam was built near the mouth of Minnehaha Creek downriver.

That dry spell had a significant impact on park property. Many park board facilities, from beach houses to boat houses and docks, were permanent structures that required proximity to the water’s edge. Parks were also landscaped and mowed to the water line and, since the depression, at least, many lakes had WPA-built shore walls that looked goofy a few feet up on dry land.

Park board annual reports provide time-lapse updates.

1948: Minnehaha Creek dry most of the year, lakes down 1.5 feet.

1949: Chain of Lakes 2 feet below normal, rainfall 2.5 inches below normal, water in Minnehaha for limited time during year

1950: Lake levels at record lows, lake channels dredged 4.5 feet deeper to allow continued use, water in Minnehaha Creek for only brief period in spring

1951: Record snowfall and heavy rains raised lake levels 0.44 feet above normal in April; flooding problems along Minnehaha Creek golf courses required dikes to make courses playable; attendance at Minnehaha Park high all year due to impressive water flow over falls.

1952: Wet early in year, dry late; lake levels stable except those that depend on groundwater runoff, such as Loring Pond and Powderhorn Lake, which were down considerably at end of year

1953: Lake levels fluctuated 1.5 feet from early summer to very dry fall; flow in Minnehaha Creek stopped in November; U.S. Geological Survey began testing water flow in Bassett’s Creek for possible diversion

1954: Again, water level fluctuations; near normal in early summer, low in fall; Minnehaha Creek again dry in November.

1955: Fall Chain of Lakes elevation lowest since 1932, but Lake Harriet near historical normal; Minnehaha dry most of year

1956: Lakes 4 feet below normal, weed control required, boat rentals incurred $10,000 loss

1957: City water — purchased at a discount! — pumped into lakes raised lake levels 1.5 feet; park board began construction of $210,000 pipeline from Bassett’s Creek, which, unlike Minnehaha Creek, had never been completely dry, to Brownie Lake.

1958: Second driest year on record; Minnehaha Creek dry second half of year; pumps activated on pipeline from Bassett’s Creek, raised water level in lakes 4.2 inches by pumping 84,000,000 gallons of water.

1959: Dry weather continued; Park board suggested reduction in water table may be result of development; Park board won a lawsuit against Minikahda Club for pumping water from Lake Calhoun to water golf course. When Minikahda donated lake shore to park board for West Calhoun Parkway in 1908 it retained water rights,  but a judge ruled the club couldn’t exercise those rights unless lake level was at a certain height — higher than the lake was at that time — except in emergencies when it could water the greens only. Lakes were treated with sodium arsenite to prevent weed growth in shallower water; low water permitted park crews to clean exposed shorelines of debris.

1960: Lake levels up 4 feet due to pumping and rain fall; channels between lakes opened for first time in two years; hydrologist Adolph Meyer hired to devise a permanent solution to low water levels.

To celebrate the rise in water levels sufficient to make the channels between the lakes navigable after being closed for a couple of years, park superintendent Howard Moore helped launch a canoe in the channel between Lake of the Isles (in background) and Lake Calhoun in 1960. He seems not to mind that one foot is in the drink. (Minneapolis Park and Recreation Board)

That’s more than a decade’s worth of weather reports. The recommendation of hydrologist Adolph Meyer was very creative: collect and recycle water from the air-conditioners in downtown office buildings and stores, and pump it to the lakes. That seemed like a good idea until the people who ran all those air-conditioners downtown thought about it and realized they could recycle all that water themselves through their own air-conditioners and save a lot of money on water bills. End of good idea. Instead the park board extended its Chain of Lakes pumping pipeline from Bassett’s Creek all the way to the Mississippi River.  But that’s a story for another time.

If you’ve followed the extensive shoreline construction at Lake of the Isles over the last many years, you know that water levels in city lakes remains an important, and costly, issue—and it probably always will be. It’s the price we pay for our city’s water-based beauty.

Afterthought: The lowest I ever remember seeing the river was following the collapse of the I-35W bridge. The river was lowered above the Ford Dam to facilitate recovery of wreckage from that tragedy. Following a suggestion from Friends of the Mississippi River, my Dad and I took a few heavy-duty trash bags down to the river bank near the site of the Meeker Island Dam to pick up trash exposed by the lower water levels. Even then the water level wasn’t as low as in the Fairchild photos.
