If it weren't for the cool weather that has us plodding along to start off the growing season, the lack of precipitation this spring season would be even more of a story. The cool weather decreases water demand from plants and the air, so helping to lessen drought impacts. The lack of moisture is certainly noticeable in area water bodies with today's featured chart looking at stream flow measurements for Squaw Creek in Ames. All the years since 1991 are plotted with the flood year of 1993, drought year of 2012, and this year highlighted on the chart. You can see this year's flows are near the bottom of observed values for early May and below were we were at during 2012. It will certainly be interesting to see where we go from here. We desperately need heat and precipitation, but getting both at the same time can be tough to come by.
Those in Ames have noticed that the two rivers in town have been running at or near bank- full for much of the summer. The featured chart displays weekly averaged stream flows for Squaw Creek at the gauge on Lincoln Way. For early September, you only find one other year (1993) with a higher stream flow since 1990.

The featured chart displays average weekly river flows for the Squaw Creek in Ames at Lincoln Way (near ISU Campus). The dry summer has river flows at zero again and resembles what happened last year. Since 1990, there isn't a comparable period to what has happened in the past two years. Between 2006 through 2010, the chart shows significant flows occurring in the late fall thanks to late season rains. The Flood of 1993 shows up nicely on this chart as the high flows lasted into the next year. The forecast does have good chances of rain for this weekend, so perhaps some water can start flowing at the gauge site again!
The featured chart displays the maximum daily river flow as measured by the gauge on Squaw Creek in Ames at Lincoln Way for each year since 1991. The chart has a logarithmic y-axis to help show the low flows. The flow this year has been on the dry side and non-existent (not measured by the sensor) for many times since July. The flood years of 1993 and 2010 are highlighted for comparison. We continue to desperately need rain and rain while the ground is still not frozen. This rain would help replenish ground water and provide a reserve for crops to use for next year.
Squaw Creek in Ames approached record levels seen back in 1993 yesterday, but came up a few inches short (18.13" versus 18.5"). The Squaw is the western river in Ames and affects the Iowa State University Campus. Many of you probably saw the water in Hilton Coliseum, that was from the Squaw. The featured image presents a comparison between 1993 and 2010 for the river gauge near Lincoln Way in Ames. With heavy rainfall expected on Friday night, it will be interesting to see how the secondary bump in river flow compares with 1993.
