River Description

Quick Facts:
Location: Central Iowa, approximately 5 miles due South from Webster City.
Shuttle Length: N/A miles. (See details in "Directions" Tab.)
Character: Aging broken out dam provides various waves/holes for 'paddle-up and play' boating.

General Overview

"Mike" wrote in Boater Talk, "there is on old dam type structure ... that turns into a great hole(s) ... A little shallow ... it is river wide with many breaks in it for easy outs. It is so old, it looks like a natural feature in terms of variations of the holes."

David Weber says, in Boater Talk, "The spot is about a 20-minute paddle upstream (0.5 mile NorthWest) from that bridge ... on the river right side of the first large island you get to."

This is just 3.7 miles (as the crow flies) away from Briggs Woods Spillway, so (when it's running) could be a 'two-fer' or each a 'back-up' plan for the other.

The wave on the river-right side of the island is a lot of fun at 1250 cfs and it is not too hard to paddle up from the bridge at that level. AMeyer.

Gage Descriptions

Unsure of best levels/ranges. Since you (generally) have paddle upstream a half-mile to get to this spot, the higher the flow, the more of a problem that will be.

Ande Meyer provides (2009-03-19):
I paddled this thing at 1250 cfs and it was a lot of fun. There was a nice balance between the current one has to paddle against to get there versus the reward enjoyed upon arrival.

Gauge/flow analysis (based on 20 years of USGS data, 1989.05.04-2009.05.03)
Drainage area at gauge: 844 sq.mi.
Minimum daily mean flow (1989.12.22): 7 cfs
90% of time flow exceeds: 35 cfs
10% of time flow exceeds: 1,830 cfs
Maximum daily mean flow (2008.06.10): 19,600 cfs
10/90 ratio ('flashy-ness'): 52.3 (under 3 is quite steady, over 10 is quite 'flashy')

Based upon USGS historical data and the listed min/max levels, expect this reach to be runnable 38 days per year (on average).
