Ozaukee Fish Passage Program
Between 2006-2013, the Ozaukee County Planning and Parks Department was awarded over $8.5 million in federal, state, local, and private funding to develop, refine, and implement a comprehensive "Ozaukee Fish Passage Program" (Program). The Program reconnects naturally existing high-quality habitat in the Lake Michigan Basin and Milwaukee River Watershed by modifying or removing impediments to fish and aquatic life passage. The Program seeks to re-establish migratory fish passage between 119,000 acres and 158 stream miles of the Milwaukee River Watershed, the Milwaukee Estuary, and Lake Michigan. Fish and other aquatic life require access to various habitats at different times of the year to reproduce, grow, feed, and survive. Human activities can directly or indirectly create impediments that fragment and inhibit access to high quality habitats. This directly affects species abundance, distribution, genetic diversity, and recreational opportunities. Passage for healthy adults moving upstream and young-of-the-year moving downstream are equally crucial. Impediments such as dams, improperly placed or sized culverts, and channelized tributary streams can prevent fish and aquatic organisms from accessing critical habitats. Wisconsin's native fish, including northern pike, are poor swimmers and jumpers and

Walleye (Sander vitreus)
Northern Pike (Esox lucius)
Lake Sturgeon (Acipenser fulvescens)
Other species of concern: Striped Shiner, Greater Redhorse, Ellipse Mussel, and Longear Sunfish
The Northern Pike Life Cycle A: Sticky eggs (up to 30,000 per female) are deposited on submerged grassy vegetation in creeks, wetlands, and road-side ditches keeping the eggs out of the sediment. Male northern pike then release milt to fertilize eggs.
B: In about two weeks, the sticky eggs turn into yolk sac larvae, which are only 8 mm long and swim for about one day.
C: The yolk sac larvae reattach to vegetation for the four or five days it takes to absorb the yolk sac.
D: Free-swimming northern pike larvae break free from vegetation and stay in warm shallow water, soon feeding on insects and other fish.
E: Northern pike grow quickly and move to larger waterbodies. One year old males (12-16") and two year old females (18-20") are ready to spawn.
F: In late March and early April, mature adults travel up streams and ditches to spawn in shallow, flooded marshy floodplain and wetland areas, returning to areas where they were born or have previously spawned.
Northern Pike Swimming Performance
-Good for short distance "bursts" of less than 15 seconds
-Fair for "sustained" movements in velocities of less than two feet per second
-Poor for "prolonged" swimming
-Short jumps of less than eight inches
-Require frequent rest areas
