Slide 1

Missouri's Oxbow Lakes Georganne Bowman Water Protection Program DNR January 24, 2006

Slide 2

Oxbow Lakes How do oxbows frame? Missouri's oxbows: What's the water like? What are they useful for? By what means would it be advisable for us to oversee oxbows?

Slide 3

Large waterway surge fields. Wind like wanders. Keeps up inclination and speed. How Do Oxbows Form?

Slide 4

How Do Oxbows Form? 1) The water within the circle, voyages slower than the water on the outside edge. This prompts to statement of silt in the corners.

Slide 5

How Do Oxbows Form? 2) Meanwhile, water on the outside of the turn streams speedier, which disintegrates the banks making the wind even more extensive. 3) The neck of the "burden" shut in.

Slide 6

How Do Oxbows Form? 4) During a high stream occasion, the wander cuts off from the primary channel. A horseshoe molded oxbow lake shapes.

Slide 7

How Do Oxbows Form? The new lake is cut off from the waterway. Flooding acquires supplements and fish. Sedimentation happens with each surge occasion. Short life expectancy.

Slide 8

Missouri and Mississippi floodplains. Littler waterways. Roughly 24 characterized Missouri's Oxbows

Slide 9

What is the water like? Exceptionally Shallow. most oxbows are under 3 meters profound. High supplement loads. Can Be Very Productive. Unless light restricted. Continually Mixed. Where's the watershed?

Slide 10

What is the water like?

Slide 11

What is the water like?

Slide 12

What is the water like? Four oxbow lakes inspected month to month summers from 1994-1996. Cooley, Sunshine, Teteseau, and Dalton. Surface zone went from 17 – 323 ha. Mean profundity at typical rise for these oxbows was < 1 meter.

Slide 13

What are they useful for?

Slide 14

What are they useful for? Huge Lake State Park: Big Lake is the biggest residual oxbow lake in Missouri. The shallow lake has a long history as a recreational range (preceding 1932). Made one of the primary open entertainment regions in northwest Missouri.

Slide 15

How Do We Manage Oxbows? Ebb and flow stream administration: Channelization shields winds from shaping. Levees keep surges from refilling. Spillover prompts to eutrophication. No new oxbows framed.

Slide 16

How Do We Manage Oxbows? Lake Dredging: "As a piece of the Page Avenue Extension, MoDOT will dig the primary body of the lake. The digging will reestablish the lake to a base profundity of 10 feet." - Creve Coeur ($10,000,000) Pumping: "The state will spend up to $2,000 every year — to facilitate the expenses of pumping — at some oxbow lakes." - St Joseph News Press Water level control for waterfowl chasing.

Slide 17

How Do We Manage Oxbows? Oxbow lakes joined State authorities ought to work St. Joseph News-Press (11/20/05) Oxbow lakes represent an exceptionally dubious problem for the condition of Missouri and the general population who live on the shores of those lakes. The lakes have a place in fact with the state. In any case, with regards to shielding the lakes from becoming scarce, the weight lands for the most part on neighborhood landowners.

Slide 18

How Do We Manage Oxbows? Gift and Curse: High natural life and entertainment esteem. Restricted asset. Long history. Be that as it may, Will never be "fantastic H 2 O". Must be looked after - expensive. Most likely not utilized for swimming.

Slide 19

How Do We Manage Oxbows? Setting Nutrient Criteria Values. Keep up hypereutrophic values? Permit these lakes to work as wetlands? Different thoughts/remarks?
